想起来我也有荔枝zero,我记得zero的原版硬件可以直接跑qt5带触摸,几乎没有特殊配置。

你的是原版硬件吗

上面大家说了很多,不再重复,建议:

1.CVBS输入,接模拟摄像头用(不知道X3是否自带CVBS, 如不带可以增加ADV7180或者TVP5150或其它)
2.USB接口充足,可以接USB摄像头
3.带RJ45网口,调试方便
4.HDMI和RGB都要。
5.最好再加个LVDS屏接口。

感谢楼主分享!

期待大佬们放demo出来,能力有限只会应用,不会pj (手动笑哭)...

楼主的做法,可能是在uboot和linux阶段都显示logo。

有些系统在两者同时显示时,可能会有花屏出现。。。 标题里面还提到了支持应用层动态修改。

达克罗德 说:

有点不解,logo文件放到文件系统的,uboot阶段就可以显示logo了,为什么还需要修改内核呢?

这个我就不清楚了,我试过 不加解锁那句,照样可以擦除成功。


歌以咏志 说:

那是不是 sf unlock 就是加锁呢?
记得 spi flash 没有锁定的指令, 我去翻翻看。

这个问题我也有疑惑,实际上这条指令是解锁的:

水一下:

#### 编译hello world

##### 测试前提
- ubuntu18 (用ubuntu16提示glibc库版本不合适,直接用18不折腾)
- 已刷 固件包firmware-20200420.tar.gz
- Q群获得arm-openwrt-linux-gcc.tar.gz

1. 安装工具链

sudo tar zxvf arm-openwrt-linux-gcc.tar.gz -C /opt
echo "export PATH=$PATH:/opt/arm-openwrt-linux-gcc/bin" >> ~/.bashrc
source ~/.bashrc

2. hello-openwrt-app.c:

#include <stdio.h>

int main(int argc, char const *argv[])
{
    printf("hello openwrt!\r\n");
    return 0;
}

3. 在ubuntu18编译并复制到开发板 (看log更直观)

有可能,文本框的资源占用少,也可能是先被重绘处理了。

如果仿真没问题,应该就是下位机处理速度不行了。

所以不要用BUTTON_SetBitmap(),自己给按钮写个回调函数,先把图片写到内存设备,在回调函数直接贴图试试是否有改善

没试过这么多按钮。

1. 你在电脑上仿真正常吗?
2. 贴图用的哪种方式。。。。。。这么多图,建议先把图片写到内存设备,再贴图。速度会快很多。

Jmhh247
回复: 4

我觉得用 mjpg-streamer 测试USB摄像头非常方便,如果能输出到LCD上就更方便了。

遗憾的是,我并没有找到这样的插件。

分析了 mjpg-streamer 源码后,我决定自己实现了一个输出到LCD的插件。

得益于 mjpg-streamer 良好的实现框架,过程很顺利,测试效果还不错,现分享给有需要的人。


- 使用方法

下载后解压到 mjpg-streamer/plugins 目录,编译得到 output_framebuffer.so 即可像其它插件一样使用了。

这里下载 : output_framebuffer_tar.gz

注意,编译的时候需要在 Makefile 里面设置好 gcc 。


- 测试效果

同时输出到 output_framebuffer  和 output_http :

mjpg_streamer -i "/usr/lib/input_uvc.so -r 640x480 -d /dev/video1" -o "/root/output_framebuffer.so" -o "/usr/lib/output_http.so -w /usr/www/"

output_framebuffer 开启了 framebuffer 双缓冲,画面稳如狗。

#### 一、本篇目标

接上篇- [[正点原子i.MX6UL]v4l2+framebuffer预览USB摄像头(三):实时预览](https://whycan.cn/t_3909.html)

撕裂问题是由于同时进行读写操作,整帧数据被破坏造成的。

如题,本篇主要实现在LCD上使用framebuffer双缓冲,实现无撕裂的实时预览USB摄像头画面。

由于本篇并不属于原定 三分天下 三步走计划,所以定为番外。


#### 二、相关概念

概念尽量简短不占篇幅,主要记录实践的过程。

framegbuffer双缓冲的资料少有完整可靠的介绍,也可能是我没有找到~

下面是我收集到的信息:

framebuffer驱动框架原生支持双缓冲,如果fb底层驱动实现了双缓冲,应用层可以直接使用,非常方便。

framebuffer双缓冲原理是基于 virtual screen 平移实现,平移实际上就是重新配置了显存的首地址。当定义的显存大于LCD实际尺寸两倍以上时,就可以通过 fb_var_screeninfo 中的 xoffset 和 yoffset 控制 x 轴或 y 轴方向的平移,一般来说只实现 y 轴上的平移就够了。

在应用代码中通过 ioctl 的 FBIOPAN_DISPLAY 指令实现平移。

- 当 yoffset = 1 时,表示显示内容向上平移一行。

		vinfo.yoffset = 1;
		ret = ioctl(fbfd, FBIOPAN_DISPLAY, &vinfo);	

- 当 yoffset = var->yres时,表示向上平移一个屏幕帧,即相当于切换缓冲区了!

		vinfo.yoffset = vinfo.yres;
		ret = ioctl(fbfd, FBIOPAN_DISPLAY, &vinfo);	

- 双缓冲切换核心代码

// ok 双缓冲测试成功,没有撕裂了!
void framebuffer_doublebuf_update(int fb_size)
{
	int ret;
	static int buf_index = 0;  


	if (buf_index)
	{
		// --更新整屏 offline
		vinfo.yoffset = vinfo.yres;
		memcpy(fb_addr + vinfo.yoffset * finfo.line_length, fb_buf1, fb_size);

		ret = ioctl(fbfd, FBIOPAN_DISPLAY, &vinfo);	

		if (ret)
		{
			printf("----FBIOPAN_DISPLAY-failed: %d \n", ret);
		}

		// printf("fb online buf : %d \n", buf_index);

		buf_index = 0;
	}
	else
	{
		// --更新整屏 offline
		memcpy(fb_addr, fb_buf1, fb_size);

		vinfo.yoffset = 0;
		ret = ioctl(fbfd, FBIOPAN_DISPLAY, &vinfo);	

		if (ret)
		{
			printf("----FBIOPAN_DISPLAY-failed: %d \n", ret);
		}

		// printf("fb online buf : %d \n", buf_index);

		buf_index = 1;
	}	
}

使用双缓冲的必要条件:
1. fb底层驱动显存大于等于LCD实际显存的2倍。
2. fb底层驱动实现fb_pan_display函数。
3. fbinfo->fix.ypanstep = 1,表示支持y轴平移。
4. var->yres_virtual >= vinfo.yres * 2(由于是可变信息,应用层修改也行)。


下面使用framebuffer版的"hello world"查看下驱动的主要信息,代码来自-[[正点原子i.MX6UL]v4l2+framebuffer预览USB摄像头(二):显示照片](https://whycan.cn/t_3888.html):

# ./fb-getinfo
success open fb dev : /dev/fb0
fb_fix.id="mxs-lcdif"
fb_fix.smem_start=0x98100000
fb_fix.mem_len=33554432             // 显存32M,远远满足双缓冲使用
...
fb_fix.ypanstep=1                   // 支持y轴平移
fb_fix.line_length=2048
fb_var.xres=1024
fb_var.yres=600
fb_var.xres_virtual=1024
fb_var.yres_virtual=600             // 不是yres的2倍,由于是可变信息,可以在应用层自己改成2倍。
fb_var.xoffset=0
fb_var.yoffset=0
...
#

可以看到已经支持双缓冲了,只用关心应用层代码。


最后需要说明一点:单纯的双缓冲并不能有效解决撕裂问题,必须配合vsync才能彻底消灭撕裂!

好消息是,NXP的fb驱动在fb_pan_display里已经实现vsync切换显存(值得新手学习),可以在应用层直接使用双缓冲。


#### 三、代码实现

本代码把采集到的USB摄像头数据,先由YUYV转成RGB888,然后由RGB888再转换成LCD需要的RGB565,最终把数据复制到显存完成显示。

重复这个过程即可实现简单的USB摄像头实时预览。

显存更新使用了带vsync的双缓冲,已经彻底消灭撕裂问题。

#### 一、本篇目标

接上篇- [[正点原子i.MX6UL]v4l2+framebuffer预览USB摄像头(二):显示照片](https://whycan.cn/t_3888.html)

如题,本篇主要实现在LCD(framebuffer)上实时预览USB摄像头画面。

有了前面两篇的代码实现,本篇的功能已经呼之欲出了,下面直接上代码。


#### 二、代码实现

本代码把采集到的USB摄像头数据,先由YUYV转成RGB888,然后由RGB888再转换成LCD需要的RGB565,最终把数据复制到显存完成显示。

重复这个过程即可实现简单的USB摄像头实时预览。

- 预览效果

由于用的yuyv格式,需要转成rgb,转换过程比较花时间,导致帧率较低。(如果用mjpg格式帧率还是不错的。)

画面快速晃动时,有明显的撕裂现象。

尽管有些瑕疵,但是这三篇不忘初心(没有太监),最终完成了原计划的功能,本篇完。

“从TF中可以”

TF卡里面的rootfs和你的NFS目录内的rootfs是否一致,如果两者一致,文件系统就不需要再修改了。
去排查其它方面



qiushan 说:

晕哥,第三步不太明白,我把根文件系统放在nfs目录里了,试过在uboot下可以使用nfs命令下载这个目录下的文件,编译好的文件系统还需要改么

- 代码纠错

今天测试程序发现拍照后颜色异常,然后发现是一处错误,有点小尴尬。。。

在函数 void yuyv_to_rgb888(void) 里面:

需要把

gbase = 0.34414 * (u - 128) - 0.71414 * (v - 128);

修改成:

gbase = 0.34414 * (u - 128) + 0.71414 * (v - 128);

(减号变成加号~)

#### 代码2 实现显示bmp照片

本程序的功能单纯就是bmp文件解码,从bmp图片文件读取RGB数据显示到framebuffer上面。

#### 一、本篇目标

接上篇- [[正点原子i.MX6UL]v4l2+framebuffer预览USB摄像头(一):采集拍照](https://whycan.cn/t_3658.html)

本篇主要实现把拍照保存的bmp图片,显示到framebuffer上。

#### 二、相关概念

一些是我自己的基本理解,比较粗糙~

帧缓冲(framebuffer)是Linux为显示设备提供的一个接口,把显存抽象后的一种设备,允许上层应用程序在图形模式下直接对显示缓冲区进行读写操作。framebuffer是LCD对应的一中HAL(硬件抽象层),提供抽象的,统一的接口操作,用户不必关心硬件层是怎么实施的。这些都是由 Framebuffer设备驱动来完成的。

- 帧缓冲设备对应的设备文件为/dev/fb*
- 使用时需要先获取到相关信息如屏幕尺寸,显存大小,RGB格式等
- 通常把帧缓冲显存映射至用户程序空间来使用,非常方便


##### s0:获取帧缓冲信息

主要是通过struct fb_var_screeninfo(表示可变信息)、struct fb_fix_screeninfo(表示固定信息)这2个结构体,在/usr/include/linux/fb.h中定义:

struct fb_fix_screeninfo {
	char id[16];			/* identification string eg "TT Builtin" */
	unsigned long smem_start;	/* Start of frame buffer mem */
					/* (physical address) */
	__u32 smem_len;			/* Length of frame buffer mem */
	__u32 type;			/* see FB_TYPE_*		*/
	__u32 type_aux;			/* Interleave for interleaved Planes */
	__u32 visual;			/* see FB_VISUAL_*		*/ 
	__u16 xpanstep;			/* zero if no hardware panning  */
	__u16 ypanstep;			/* zero if no hardware panning  */
	__u16 ywrapstep;		/* zero if no hardware ywrap    */
	__u32 line_length;		/* length of a line in bytes    */
	unsigned long mmio_start;	/* Start of Memory Mapped I/O   */

- 获取可变信息:

    if (ioctl(screen_fbd, FBIOGET_VSCREENINFO, &fb_var) == -1) {
        printf("err read screen info FBIOGET_VSCREENINFO.\n");
        close(screen_fbd);
        return 0;
    }

- 获取固定信息:

    if (ioctl(screen_fbd, FBIOGET_FSCREENINFO, &fb_fix) == -1) {
        printf("err read screen info FBIOGET_FSCREENINFO.\n");
        close(screen_fbd);
        return 0;
    }

##### s1:把帧缓冲映射至用户空间
映射显存:

    if ((fb_addr = (char*)mmap(0, fb_size, PROT_READ | PROT_WRITE, MAP_SHARED, fbfd, 0)) < 0) {
        printf("fb mmap error\n");
        exit(1);
    }

取消映射:

    munmap(fb_addr, fb_size);

#### 三、代码实现

- 代码1

本代码主要实现了获取帧缓冲的信息,相当于帧缓冲版的"hello world"。

可以看到,屏用的是RGB565格式,而显存居然达32M,NXP的驱动工程师很任性~

你的驱动不支持双缓冲。

The mem is :2457600 = 600 * 4096,显存明显只一个帧缓冲大小。

必须大于双缓冲以上的显存,y_virtual 才能翻倍。

换成4.19的内核也不行,现在的问题是 不管overalloc更改成200,还是300,系统中的y_virtual 都是600

好像又可以水一帖~

可以写个最简单的程序测试下qt支持的图片格式:

- 测试代码:

#include <QImageReader>

qDebug() << QImageReader::supportedImageFormats();

- ubuntu下测试输出:

("bmp", "cur", "gif", "ico", "jpeg", "jpg", "pbm", "pgm", "png", "ppm", "xbm", "xpm")

- 交叉编译后在你的开发板上测试。

不在电脑旁,没法看代码。
只用改设置字体的c文件就行。

我只用过MDK编译,不知道和编译器是否有关

可以试试不带bom的utf8格式

#### 拍照代码测试Ok

#### 代码2 实现拍照功能

运行程序后会在当前目录生成uvc_grap.bmp。可以复制到ubuntu查看图片。

- 知识点

主要是自己的理解。

1.yuyv与rgb888:

yuyv原始数据里,两个像素点共用了uv分量,两个像素占用4个字节;
rgb888大家应该都知道了,一个像素点占用3个字节,那么两个像素点占用6个字节。
由此可知,yuyv与rgb888字节量比列是 4:6,也就是 2:3。

知道这些就可以定义相关数据缓冲区大小了:

// buf for yuyv
uvc_cam.framesizeIn = uvc_cam.width * uvc_cam.height << 1; // w * h * 2
uvc_cam.framebuffer = (unsigned char*)calloc(1, (size_t)uvc_cam.framesizeIn);

// buf for rgb888
static unsigned char rgb888_buffer[IMAGEWIDTH * IMAGEHEIGHT * 3];

2.bmp:

基础的图片格式网上很多介绍,不再说明,核心关注点是——数据上下颠倒存放的

### 开篇
2020年,注定是不平凡的一年,就当是纸老虎吧。
我遇到的第一个纸老虎是v4l2。
不能出门,就想着玩下USB摄像头,想实现的功能是在LCD屏上实时预览USB摄像头的画面。
搜资料,知道要用v4l2来驱动USB摄像头,第一个难点就是“v4l2”怎么读都不顺。。。
最终,跳过这个难点,确定了使用v4l2+framebuffer预览USB摄像头画面。
参考把“大象放进冰箱”,我决定把实现分成三步,以降低难度、建立信心。

本篇主要实现采集拍照。

### 正题

#### 一、相关概念
概念尽量简短不占篇幅,主要记录实践的过程。

- USB摄像头用的是UVC(USB Video Class)标准类,免驱。
- v4l2(Video for linux2)是linux提供的视频设备编程API。
- USB摄像头一般都支持输出YUV数据。
- YUV是一种颜色空间,通常需要转成RGB使用(bmp保存或LCD显示,等)。
- YUYV是YUV的一种,也叫YUV422。
- BMP图是RGB数据,上下颠倒存放的。

#### 二、操作分解
v4l2驱动USB摄像头的采集流程还是容易看明白,大致是:打开摄像头设置参数,申请设置缓冲区,然后从缓冲区每次读一帧即可。

##### s0.核心指令
v4l2 主要通过调用 ioctl 配合一系列 VIDIOC_XXXXXX 指令完成,很友好。

#include <sys/ioctl.h>
#include <linux/videodev2.h>

##### s1.打开摄像头
俗话说,一切皆文件。

#include <fcntl.h>

fd = open("/dev/videox", O_RDWR);

##### s2.获取属性

ioctl(fd, VIDIOC_QUERYCAP, &cap);

##### s3.设置参数
输出格式、分辨率、帧率等。

ioctl(fd, VIDIOC_S_FMT, &fmt);
ioctl(fd, VIDIOC_S_PARM, &setfps);

##### s4.设置缓冲区
- 简单理解就是配置FIFO(先进先出环形队列)。
- 映射到用户空间。
- 核心操作围绕struct v4l2_buffer结构体的index成员变量。

struct v4l2_buffer buf;

// 出队
ioctl(fd, VIDIOC_DQBUF, &buf);

// 入队
ioctl(fd, VIDIOC_QBUF, &buf);

##### s5.采集控制

int type = V4L2_BUF_TYPE_VIDEO_CAPTURE;

// 启动采集
ioctl (fd, VIDIOC_STREAMON, &type);

// 停止采集
ioctl (fd, VIDIOC_STREAMOFF, &type);

##### s6.采集一帧

ioctl(fd, VIDIOC_DQBUF, &buf);

##### s7.视频处理
转换成RGB,然后保存成BMP图片实现拍照。


#### 三、代码实现

主要参考了开源项目MJPG-streamer的v4l2采集代码,完全手打。

- 代码1

本代码主要实现了获取USB相机的信息,相当于v4l2版的"hello world"。

有区别,但是可以用。

楼主用stm32吗,就像你用KEIL4和KEIL5都可以编译stm32的程序,虽然两者的版本不一样。。。宏观上差不多可以这样理解~


Gentlepig 说:

那,两个Gcc版本不一致也没事?

#65 Re: NXP i.MX6UL/6ULL » 请教,交叉编译器gcc和文件系统里的gcc是一回事吗? » 2020-01-15 10:05:40

- 内核里面没有gcc
- 一共有两个交叉工具链
- 7.4.0是你在ubuntu的交叉工具链,是在ubuntu上用的。
- 根文件系统里面的gcc,是在开发板上用的。
- 两个gcc都可以编译linux程序,然后在开发板上运行。

你仔细想想,差不多是一回事,又不是一回事。

### 一、用buildroot制作根文件系统

- 出厂根文件系统用的是yocto,制作太难了。
- 用buildroot相对简单,相关支持可能不如yocto。
- 先制作根文件系统的目的是生成工具链。


使用buildroot2017,这里下载:buildroot-2017_08_1_tar.gz



##### s1. 解压

```
tar xvf buildroot-2017.08.1.tar.gz 

```

##### s2. 配置

```
cd buildroot-2017.08.1/

make menuconfig
```

控制篇幅只列出部分,这里有个参考配置(不是压缩文件,需要改名为.config):yz_imx6u_buildroot2017-v1_config.rar

```

##### s3. 编译

```
time make
```

- 编译的根文件系统在这里:buildroot-2017.08.1/output/images/rootfs.tar


- 工具链位置在这里:buildroot-2017.08.1/output/host/bin/arm-buildroot-linux-gnueabihf-


##### s4. 工具链设置脚本

- 方便后面编译uboot、linux,写一个脚本。
- 脚本是临时有效的,每次编译时先执行此脚本。


build-set-yz-imx6ul-env.sh 实现:

```
#! /bin/sh

echo "set env"
export PATH=$PATH:/home/vmtest/work/yuanzi/code-build/rootfs/buildroot-2017.08.1/output/host/bin
export ARCH=arm
export CROSS_COMPILE=arm-buildroot-linux-gnueabihf-

echo "done"
```

---
### 二、编译u-boot

u-boot源码在:阿尔法Linux开发板光盘资料(A盘)\1、例程源码\11、开发板教程对应的uboot和linux源码里面

##### s1. 复制 uboot-imx-rel_imx_4.1.15_2.1.0_ga_alientek.tar.bz2 到 ubuntu16

```
# 新建目录,复制到这里
mkdir uboot
```

##### s2. 解压

```
cd uboot
tar xjvf uboot-imx-2016.03-2.1.0-gd9420c3-v1.1.tar.bz2
```

##### s3. 编译

```
# 1.脚本配置工具链
source build-set-yz-imx6ul-env.sh

# 2.配置uboot
make distclean
make mx6ull_14x14_ddr512_emmc_defconfig

# 3.编译
make all -j6

# 4.改名
mv u-boot.imx u-boot-imx6ull-14x14-ddr512-emmc.imx

```

最终得到 u-boot-imx6ull-14x14-ddr512-emmc.imx.



---
### 三、编译linux
linux源码在:阿尔法Linux开发板光盘资料(A盘)\1、例程源码\11、开发板教程对应的uboot和linux源码里面

##### s1. 复制 linux-imx-4.1.15-2.1.0-gbedf008-v1.1.tar.bz2 到 ubuntu16

```
# 新建目录,复制到这里
mkdir linux
```

##### s2. 解压

```
cd linux
tar xjvf linux-imx-4.1.15-2.1.0-gbedf008-v1.1.tar.bz2
```

##### s3. 编译

- 编译前先安装 lzop

```
sudo apt-get install lzop
```

- 编译linux

```
# 1.脚本配置工具链
source build-set-yz-imx6ul-env.sh

# 2.配置内核
make distclean
make imx_v7_defconfig

# 3.编译
time make -j6
make -j6 imx6ull-14x14-emmc-7-1024x600-c.dtb

# 4.安装模块
rm -rf m_out
mkdir m_out

make -j6 modules_install INSTALL_MOD_PATH="./m_out"
```
- 打包模块

mfgtool需要用到。
```
cd m_out/lib/modules/
sudo tar cjvf ../modules.tar.bz2 .
```

##### 生成相关文件位置:

- 内  核:arch/arm/boot/zImage
- 模  块:m_out/lib/modules.tar.bz2
- 设备树:arch/arm/boot/dts/imx6ull-14x14-emmc-7-1024x600-c.dtb

---
### 四、打包rootfs

##### s1.汇总前面得到相关文件到一个目录内,如下:

```
.
├── imx6ull-14x14-emmc-7-1024x600-c.dtb
├── modules.tar.bz2
├── pack_yz_imx6ul_rootfs-v1.sh
├── rootfs.tar
├── u-boot-imx6ull-14x14-ddr512-emmc.imx
└── zImage

0 directories, 6 files

```

其中,pack_yz_imx6ul_rootfs-v1.sh是个脚本,目的是处理成mfgtool需要的格式,很简单,内容如下:

```
#! /bin/sh

echo "s1: start pack..."
rm -rf imx6ul_rootfs
mkdir -p imx6ul_rootfs/rootfs

rm -f rootfs.tar.bz2


echo "s2: tar xf rootfs.tar..."
tar xf rootfs.tar -C imx6ul_rootfs/rootfs/
mkdir imx6ul_rootfs/rootfs/lib/modules
sync

echo "s3: tar xjf rootfs.tar.bz2..."
cd imx6ul_rootfs/rootfs
tar cjf ../rootfs.tar.bz2 .
sync

cd ..
cd ..

echo "s4: cp rootfs.tar.bz2..."

cp imx6ul_rootfs/rootfs.tar.bz2 ./
sync

rm -rf imx6ul_rootfs

echo "pack done."

```

##### s2. 执行脚本

```
vmtest@linux-test:~/work/yuanzi/code-build/bin-bak$ sudo ./pack_yz_imx6ul_rootfs-v1.sh 
s1: start pack...
s2: tar xf rootfs.tar...
s3: tar xjf rootfs.tar.bz2...
s4: cp rootfs.tar.bz2...
pack done.
vmtest@linux-test:~/work/yuanzi/code-build/bin-bak$ 

```

执行脚本后得到 rootfs.tar.bz2。

```
.
├── imx6ull-14x14-emmc-7-1024x600-c.dtb
├── modules.tar.bz2
├── pack_yz_imx6ul_rootfs-v1.sh
├── rootfs.tar
├── rootfs.tar.bz2
├── u-boot-imx6ull-14x14-ddr512-emmc.imx
└── zImage

0 directories, 7 files

```

到这里,所需要的文件都准备好了,可以召唤神龙了 可以烧录到emmc了。


---
### 五、烧录固件到emmc

- 在win10下操作。
- mfgtoo位置:阿尔法Linux开发板光盘资料(A盘)\5、开发工具\4、正点原子修改过的MFG_TOOL烧写工具


##### s1.替换相关文件

```
#1
modules.tar.bz2 复制到 mfgtool\Profiles\Linux\OS Firmware\files\modules

#2
rootfs.tar.bz2 复制到 mfgtool\Profiles\Linux\OS Firmware\files\filesystem

#3 
uboot、zImage、dtb 复制 mfgtool\Profiles\Linux\OS Firmware\files\boot
```

##### s2.烧录固件
烧录过程和正常烧录一样,控制篇幅不再列出,可参考官方文档或者这个帖子-[ [正点原子i.MX6UL开发板] 开箱与固件烧录](https://whycan.cn/t_3521.html).


---

### 六、编译qt例程
qt自带例程的编译可以参考晕哥这个视频:- [buildroot成功后如何编译Qt应用程序]( https://www.bilibili.com/video/av16396112/)

看log或许更直观:

```

有点懵,野火的板子为啥用原子的mfgtools。。。


Gentlepig 说:

我买的是野火的mini板。
原子的资料要从网盘下,4G多,我这里下载速度才100K/s,要五六个小时。
费劲从nxp官网下载了mfgtools,结果运行后,连不上板子...

手头又没tf卡了,3个卡都格式化不聊了,悲催。

问题不大,win10下的mfgtool烧回出厂固件,继续折腾~


Gentlepig 说:

玩死了...
本来想重启板子,应该输入reboot,结果忘记命令了,输了几次reset,后来重启后,进不去系统了,串口没有调试信息了。
拨码开关设到usb模式,结果启动后串口也没调试信息,而且用uuu -lsusb命令,也查不到设备了...

为楼主的钻研精神点赞,话说win下面的mfgtool不香吗

只要不变砖,mfgtool几乎用不到了,楼主可以把时间花在应用上。

只是建议,当然多折腾也是收获。

回复: 7

关键字: 正点原子,i.MX6UL,linux


- 主机环境:ubuntu16.04-64bit
- 硬件版本:正点原子i.MX6UL emmc


首先,要感谢晕哥,免费提供了<正点原子i.MX6UL开发板>试玩,真香!

由于是全新未拆的,所以我决定水一帖开箱。

- 正点原子官方资料页:- [ 【Linux视频文档发布】正点原子150讲视频+1500页Linux教程发布,配套Alpha Linux开发板,请赶紧下载学习  ](http://www.openedv.com/thread-300792-1-1.html)

---

### 一、简单开箱

人狠话不多,先上几张图

- 包装
1.png

- 内部
2.png

- 启动
qt-demo.png



出厂自带qt-demo看着挺不错,每个功能的“返回”是需要下拉屏幕边缘的,简单点说,这个操作用起来是生不如死

好在官方有提供新固件,为每个app的功能都提供了一个“返回”按钮,赶紧烧个新固件吧~

---
### 二、固件烧录

1. 去官方资料页里下载A盘的资料包
2. 在资料包的“开发工具”里面找到-正点原子修改过的MFG_TOOL烧写工具
3. 解压后双击-Mfgtool2-eMMC-ddr512-eMMC.vbs 启动烧写工具
4. 找根USB线接到开发板USB-OTG和电脑
5. 设置开发板拨码开关为:0100 0000
6. 上电,烧写工具会提示“符合厂商HID设备”
7. 点击“start”,开始烧录(此时串口也会输出信息)
8. 需要漫长的10多分钟,等待烧录完成。


新固件的界面是这样的(看样子是换了个不同口味的美工):

new-qt.png

烧个固件要等10多分钟,赶紧试试NFS挂载吧~

---
### 三、NFS挂载根文件系统

这里只用NFS挂载根文件系统,其它的kernel,dtb等都用出厂的。

根文件系统是我用buildroot做的,功能不重要,目的是测试NFS挂载。


##### 进入uboot命令行设置启动参数:

- 设置 bootargs

```
setenv bootargs "console=${console},${baudrate} root=/dev/nfs ip=172.16.1.100:172.16.1.33:172.16.1.1:255.255.0.0:imx6ull:eth0:off rw nfsroot=172.16.1.33:/nfsroot/imx6ull-nfs/buildroot2017-rootfs";saveenv

```

- 设置 bootcmd

```
setenv bootcmd “mmc dev 1;mmc dev 1; mmc rescan;fatload mmc 1 0x80800000 zImage;fatload mmc 1 0x83000000 imx6ull-14x14-evk.dtb;bootz 0x80800000 - 0x83000000”;saveenv
```

bootcmd 设置后,开发板自动从NFS启动。

确实用到了cvNameWindow,程序只有简单几行:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    // read an image
    cv::Mat image = cv::imread("1.jpg", 1);
    // create image window named "My Image"
    cv::namedWindow("My Image 2019");
    // show the image on window
    cv::imshow("My Image2019", image);
}


这个 libgtk很尴尬,我也看到错误提示,但是buildroot里面根本找不到  libgtk2.0 !  ...可能是我姿势不对吧

下面我截个图
---
- buildroot里面可以搜索到 libgtk2:
serlibg.png

- 实际去选择找不到,也没任何依赖提示
lib2err.png


你能找到libgtk2吗

请教,你用buildroot哪个版本

buildroot里面的opencv,需要特别配置吗,我配置不成功


我试过buildroot2017 编译opencv,程序可以编译通过,但是放在v3s运行会出错:

# ./testopencv

太一酱鸭 说:

来反馈一下后续情况,并没有成功使用,最后还是v4l2底层调用获取图片了,bsp驱动并不能和opencv匹配。
只能将目前发现的问题暂时和大家分享一下。
1、必须指定vidioc_s_input设置,opencv只做了g_input。
2、我的摄像头驱动即使设置了不支持的格式也不会返回错误,cap_v4l会一开始就尝试设置这个格式,返回错误才接着设置其他格式。摄像头并不支持BGR24但没有返回错误导致最后取不到帧或者帧全黑。
但是这里我即使注释掉其余的把摄像头帧格式设置成UYVY(cap_v4l会自行做UYVY_TO_BGR的转换),获取到的图片会有四小块且是绿色的。目前找不到错误在哪,所以直接放弃更改cap_v4l.cpp。
注:之前我勾选了buildroot里的libv4l,opencv就会编译cap_libv4l.cpp来进行v4l2调用,不推荐这个,因为这个只支持bgr24没有格式转换代码。

    case WM_PAINT:

        // 背景
        GUI_DrawBitmap(&bmscar1, 0, 0);

        // 圆角矩形

Image控件我用的比较少,我也没有验证过你这种背景的做法是否正确。

emwin例程里面一般在WM_PAINT里,用GUI_DrawBitmap之类去绘制背景实现。


区别在于:
1. 你用的控件去做背景
2. 常规做法是用2D绘图做背景

不显示的原因,可能是你的控件挡住了2D绘图。

以上是我的推测,未经验证。

大佬,您好!再请教一个问题:我看了你做的界面,很漂亮。我发现我的界面要求和你的稍微有区别:我的窗口背景是一张图片。你的背景好像是颜色填充。这个区别是不是导致了我无法显示矩形呢?
还有,上面帖子里贴的代码不完整,重新贴在下面:
WM_PAINT:
    hImage=WM_GetDialogItem(hDlg, ID_IMAGE_0);
        IMAGE_SetBitmap(hImage,&bmbackground);

楼主,你这个问题,最好把代码片断贴出来,好分析。。。


现在只能猜一下了:

1. 单独测试矩形是否能显示出来?
2. 单独显示背景图是否能显示出来?
3. WM_PAINT消息里面绘图,是有顺序的。
4. 以上都正常,先绘制背景图,再绘制矩形试试。

测试一下:环形进度条动画延迟效果


(只是测试,比较简陋,暂时不整理工程出来~)


- 动画延迟

动画延迟效果,就是有一个收敛的过程,不是一步到位的。

比如抽奖的表盘,不是你转一下就停,而是有一个延迟过程才停下来。


!!!----("动画延迟"-这个叫法可能不专业~)


---
- 动态展示

只有第1个环形进度条带延迟效果,仔细看可以看到,其它进度条都是直接停下来,而第1个进度条经过一段延迟才停下来。

(gif有撕裂感,是gif工具的问题,实际很流畅)

##### 原理是:不直接更新设置值,而是通过一个定时器间接更新设置值,从而实现动画延迟。

- 核心代码

##### 原理就是用emwin系统的皮肤设置函数+按钮私有数据。这相当于一种自定义控件实现的简单方法,通过不同的函数+数据结构就能实现不同功能的控件。


!!!--------(延用了上个帖子的代码,整理的有点粗糙~)


1. 结构体类型

typedef struct {
    int Check;
    GUI_COLOR colorPressed;
    GUI_COLOR colorUnPress;
    GUI_FONT *iconFont;
    char iconName[6];
    char btnText[10];
    int ch;
    int sw;
    int mode;
    float batV;
    int batI;
    float power;
} BATINFO_USER_SKIN;


2. 结构体定义

static BATINFO_USER_SKIN BatInfoData[] = {
    {ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf0f6", "stm8", 1, 1, ZL_BATINFO_MODE_CC, 12.305, 2000},
    {ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf030", "stm32", 2, 1, ZL_BATINFO_MODE_ST, 10.8, 1500},
    {ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf008", "mcu", 3, 0, ZL_BATINFO_MODE_CV},
};

static BATINFO_USER_SKIN *pBtnUser[GUI_COUNTOF(BatInfoData)];


3. 控件用户接口

(这里只完成了最有用的部分,有源码可以按需魔改。。。)


// !!!----以下接口必须在控件初始化私有数据后才能调用----

// 设置环形值 ok
int zl_roundlevel_set_value(WM_HWIN hItem, int value)
{
    BATINFO_USER_SKIN *pUsr;
    char strbuf[6];


    if (value > 100) {
        value = 100;
    }

    // 更新进度环
    BUTTON_GetUserData(hItem, &pUsr, sizeof(pUsr));
    pUsr->ch = value;


    // 更新数字值
    sprintf(strbuf, "%i %%", value);
    BUTTON_SetText(hItem, strbuf);
}

// 设置进度条颜色 ok
int zl_roundlevel_set_color(WM_HWIN hItem, GUI_COLOR color)
{
    BATINFO_USER_SKIN *pUsr;

    BUTTON_GetUserData(hItem, &pUsr, sizeof(pUsr));
    pUsr->colorPressed = color;

    WM_InvalidateWindow(hItem);
}

// 设置文字颜色 ok
int zl_roundlevel_set_valuecolor(WM_HWIN hItem, GUI_COLOR color)
{
    BUTTON_SetTextColor(hItem, BUTTON_CI_UNPRESSED, color);
    BUTTON_SetTextColor(hItem, BUTTON_CI_PRESSED, color);
}

4. 环形进度条实现代码


// 环形进度条实现  ok
int button_drawskin_roundlevel(const WIDGET_ITEM_DRAW_INFO* pItem)
{
    BATINFO_USER_SKIN *pUsr;
    char acBuf[20];
    int xPos;
    int yPos;
    int r;



	switch (pItem->Cmd)
	{
	case WIDGET_ITEM_DRAW_BACKGROUND:

		    BUTTON_GetUserData(pItem->hWin, &pUsr, sizeof(pUsr));

			if (BUTTON_IsPressed(pItem->hWin))
			{
                GUI_SetColor(pUsr->colorUnPress);
			}
			else
			{
                GUI_SetColor(pUsr->colorUnPress);
			}


            // 计算半径
			r = (pItem->x1 < pItem->y1) ? pItem->x1 : pItem->y1;

			if (r % 2) {
                r -= 3;
			}
			else {
                r -= 2;
			}

			xPos = pItem->x1 / 2;
			yPos = pItem->y1 / 2;

			// 外圆
			GUI_AA_FillCircle(xPos, yPos, r / 2);

			// 内圆
            GUI_SetColor(GUI_DARKCYAN);
			GUI_AA_FillCircle(xPos, yPos, r / 2 - (r / 6));

			// 进度环
			GUI_SetColor(pUsr->colorPressed);
			GUI_SetPenSize(r/6 - 1);
			GUI_AA_DrawArc(xPos, yPos, r / 2 - (r / 6 / 2) - 1, 0, 0, pUsr->ch * 3.6);

        break;

	default:
		{
			return BUTTON_DrawSkinFlex(pItem);
		}
	}
	return 0;
}

关键字: emwin, 自定义控件,卡片面板

这是一个用emwin写的主页面导航+侧边导航的通用程序框架,emwin仿真环境用的是codeblocks(16或17都可)。


##### 本坛首发。

本篇主要介绍了一种卡片式的自定义控件。(由于只是程序框架,所以并不涉及界面美化,我知道丑,所以先说出来~)

- 卡片面板

卡片面板是我自己起的名字,不知道此类控件是否有准确的叫法。

在横屏设备中,卡片面板有着大量的应用,通常用来展示同类信息。

下面的截图来自最近沉迷的手游《QQ飞车》。(飞车一局2分钟左右,比王者玩起来轻松太多了,当然我主要是为看它的GUI设计,信吧~)

- 代码实现

##### 原理就是用emwin系统的皮肤设置函数+按钮私有数据。这相当于一种自定义控件实现的简单方法,通过不同的函数+数据结构就能实现不同功能的控件。


1. 结构体类型

typedef struct {
    int Check;
    GUI_COLOR colorPressed;
    GUI_COLOR colorUnPress;
    GUI_FONT *iconFont;
    char iconName[6];
    char btnText[10];
    int ch;
    int sw;
    int mode;
    float batV;
    int batI;
    float power;
} BATINFO_USER_SKIN;


2. 结构体定义

static BATINFO_USER_SKIN BatInfoData[] = {
    {ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf0f6", "stm8", 1, 1, ZL_BATINFO_MODE_CC, 12.305, 2000},

    {ZL_BTN_CHKMODE_NO, GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont24, "\uf008", "mcu", 3, 0, ZL_BATINFO_MODE_CV},

FluxBB bbcode 测试

#### emwin使用awesome字体

awesome图标字体有提供ttf格式,而emwin是支持ttf格式的,所以emwin可以直接使用。


emwin使用图标的常规方法,无非就是2D绘图,直接贴图等。

awesome图标字体ttf格式大小只有162KB,不到200KB就有675个矢量图标,显然是很适合嵌入式的,使用方法也简单的多。

FluxBB bbcode 测试

所以在一些场合中使用awesome图标字体优势非常大。



- 简单使用示例

创建字体后,直接当成普通字体来显示即可:

GUI_SetFont(&Font48);

GUI_DispStringInRect("\uf085", &rect, GUI_TA_HCENTER | GUI_TA_TOP);

上面的“f085”是从索引页查出图标对应的unicode。我把图标的索引页生成了一个PDF文档,后面会给出该文档。



- 进阶使用示例

就是本次导航按钮使用图标字体的实现方法,原理就是用emwin系统的皮肤设置函数+按钮私有数据。

1. 在emwin创建awesome图标字体;

        ttf_init();

        // 篇幅限制,只列出部分,具体看工程源码
	/* 创建6种字体 */
	GUI_TTF_CreateFontAA(&awefont16, &awefont_Cs0);
	GUI_TTF_CreateFontAA(&awefont24, &awefont_Cs1);
	GUI_TTF_CreateFontAA(&awefont32, &awefont_Cs2);
	GUI_TTF_CreateFontAA(&awefont48, &awefont_Cs3);
	GUI_TTF_CreateFontAA(&awefont72, &awefont_Cs4);
	GUI_TTF_CreateFontAA(&awefont120, &awefont_Cs5);

---
2. 增加按钮的私有数据,这里是记录图标字体等信息


// 按钮私有数据,记录图标
// ok
static BTN_USER_SKIN BtnSkinData[] = {
    {GUI_DARKCYAN, GUI_DARKMAGENTA, &awefont48, "\uf0f6"},
    {GUI_DARKCYAN, GUI_DARKGRAY, &awefont48, "\uf030"},
    {GUI_DARKCYAN, GUI_DARKGREEN, &awefont48, "\uf008"},
    {GUI_DARKCYAN, GUI_DARKRED, &awefont48, "\uf226"},
    {GUI_DARKCYAN, GUI_ORANGE, &awefont48, "\uf144"},
    {GUI_DARKCYAN, GUI_GRAY_9A, &awefont48, "\uf2b5"},
};

// ok
static BTN_USER_SKIN *pBtnUser[GUI_COUNTOF(BtnSkinData)];

然后一定记得给按钮设置私有数据的字节数:

3. 使用系统函数设置皮肤即可


    for (int i = 0; i < GUI_COUNTOF(BtnSkinData); i++) {

        hItem = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_0 + i);

        BUTTON_SetFont(hItem, &Font16);

        // 设置皮肤函数
        BUTTON_SetSkin(hItem, button_drawskin_awefont);

        pBtnUser[i] = &BtnSkinData[i];

        // 设置私有数据
        BUTTON_SetUserData(hItem, &pBtnUser[i], sizeof(pBtnUser[i]));
    }

---

4. 最后是自定义皮肤函数的实现,核心代码


/* 按钮绘制图标字体皮肤 ok*/
int button_drawskin_awefont(const WIDGET_ITEM_DRAW_INFO* pItem)
{
    BTN_USER_SKIN *pUsr;
    GUI_RECT rect;
    char acBuf[20];


	switch (pItem->Cmd)
	{
    case WIDGET_ITEM_DRAW_TEXT:

            BUTTON_GetText(pItem->hWin, acBuf, sizeof(acBuf));

            rect.x0 = pItem->x0;
            rect.x1 = pItem->x1;
            rect.y0 = pItem->y0;
            rect.y1 = pItem->y1;


            GUI_SetFont(BUTTON_GetFont(pItem->hWin));
            GUI_SetTextMode(GUI_TM_TRANS);
            GUI_SetColor(GUI_WHITE);

            rect.y1 -= rect.y1 / 6;
			GUI_DispStringInRect(acBuf, &rect, GUI_TA_HCENTER | GUI_TA_BOTTOM);


        break;

	case WIDGET_ITEM_DRAW_BACKGROUND:

		    BUTTON_GetUserData(pItem->hWin, &pUsr, sizeof(pUsr));

			if (BUTTON_IsPressed(pItem->hWin))
			{
                GUI_SetColor(pUsr->colorPressed);
			}
			else
			{
                GUI_SetColor(pUsr->colorUnPress);
			}

			GUI_AA_FillRoundedRect(pItem->x0, pItem->y0, pItem->x1, pItem->y1, 0);


            rect.x0 = pItem->x0;
            rect.x1 = pItem->x1;
            rect.y0 = pItem->y0;
            rect.y1 = pItem->y1;



            // 图形字体
            GUI_SetColor(GUI_WHITE);
            GUI_SetTextMode(GUI_TM_TRANS);


            rect.y0 += rect.y1 / 6;

            if (pUsr->iconFont) {
                GUI_SetFont(pUsr->iconFont);
                GUI_DispStringInRect(pUsr->iconName, &rect, GUI_TA_HCENTER);

            }


        break;

	default:
		{
			return BUTTON_DrawSkinFlex(pItem);
		}
	}
	return 0;
}

我把楼主的文件写到TF卡, 然后 dump 出来一个 bin 文件, 大家可以测试下载: f1c100s_4_14_128M_tfcard_dump_bin.7z

解压后 dd 到 TF 卡即可:

sudo dd if=f1c100s_4.14_128M_tfcard_dump.bin of=/dev/sdX

1. 添加了可执行文件 etc/init.d/S50adbd

#! /bin/sh
modprobe g_ffs idVendor=0x18d1 idProduct=0x4e42 iSerialNumber="buildroot"
mkdir -p /dev/usb-ffs/adb
mount -t functionfs adb /dev/usb-ffs/adb -o uid=2000,gid=2000
adbd &

2. 免输入密码登录,  修改 etc/inittab

console::respawn:/sbin/getty -L  console 0 vt100 # GENERIC_SERIAL

改为:

console::respawn:-/bin/sh


这样处理之后, 插入USB就能自动进入ADB, 什么命令都不用输入了。

请教晕哥,用你提供的bin,进去之后是这个样子。adb这里显示乱码,正常吗

804715358@qq.com 说:

楼主,您好,ts = ts_setup(NULL, 1);这个函数在哪里实现的,我这里用您的配置报错

1. 这个函数就是tslib自己的API

在tslib.h里面可以看到

TSAPI struct tsdev *ts_setup(const char *dev_name, int nonblock);

正常情况下,只要在应用程序里包含 tslib.h头文件,并且链接了tslib的库,就可以用这些API了。


2. 关于配置报错。这些配置的前提是,tslib已经移植好,可以正常工作。

你需要确认tslib是否能正常工作。(我也是新手,用的是buildroot自动编译好的tslib,本篇笔记不涉及tslib编译。。。)

nuvoton 说:

应该是免配置的, 因为搜到的 ubuntu sdl2 ffplay 只要安装 sdl2 & directfb 包就可以跑。

或者你在这个地方跟踪进去, 看是什么原因导致错误:

directfb not available


从源码看还是video驱动的问题,有时间继续看看:

    /* Select the proper video driver */
    index = 0;
    video = NULL;
    if (driver_name == NULL) {
        driver_name = SDL_getenv("SDL_VIDEODRIVER");
    }
    if (driver_name != NULL) {
        for (i = 0; bootstrap[i]; ++i) {
            if (SDL_strncasecmp(bootstrap[i]->name, driver_name, SDL_strlen(driver_name)) == 0) {
                if (bootstrap[i]->available()) {
                    video = bootstrap[i]->create(index);
                    break;
                }
            }
        }
    } else {
        for (i = 0; bootstrap[i]; ++i) {
            if (bootstrap[i]->available()) {
                video = bootstrap[i]->create(index);
                if (video != NULL) {
                    break;
                }
            }
        }
    }
    if (video == NULL) {

我这个勾选 directfb 之后, cairo 就可以跑了。


这能说明directfb正常工作了吧,看帖子里你用的是SDL1。。。


晕哥,编译后,directfb需要怎么配置吗,就是那个directfbrc文件,还是免配置直接运行的

不带你们这样玩的啊, 晕哥,SDL2还是要填坑的!!!


我用buildroot2017制作根文件系统,就是这荔枝派教程帖子里 https://whycan.cn/t_561.html ,目的是想用用ffplay。


所以选中ffmpeg和ffplay编译,因为ffplay需要SDL2支持,所以buildroot自动选中了SDL2。

buildroot编译成功后测试:ffplay xx.mp4

也是提示:Could not initialize SDL - No available video device。



一翻搜索,说是SDL2需要directfb。

buildroot选中directfb,继续编译测试。

设置export SDL_VIDEODRIVER=directfb,运行ffplay,显示:

Could not initialize SDL - directfb not available
(Did you set the DISPLAY variable?)


后面怎么破。。。

即然是客户接收有问题,无论你用何种方式都避免不了,只是看几率大小

要解决问题,还是得让客户改程序。按照你的描述,客户的程序得拼帧。

晕哥,

找时间出个详细点的教程吧,关于荔枝派zero的usb虚拟串口和虚拟网口的,感觉这两个功能很实用!

救救孩子吧。。。 lol

我还测试了荔枝派官方的教程-- Zero通过otg与PC共享网络

说配置后可以看到usb0
zp@ubuntu64:~$ ifconfig
...
usb0 Link encap:Ethernet HWaddr 66:36:e9:13:fd:44

root@Lichee:~# ifconfig
...
usb0 Link encap:Ethernet HWaddr 2e:cf:e1:3f:ad:61

--------------
结果在我的板子上根本看不到usb0

不知道晕哥测试过没

总感觉我这块荔枝派不太稳定,准备再入一块。

晕哥,

我昨晚测试荔枝zero,内核也是的用4.13y,USB Gadget Support在官方默认配置下,是CDC Composite Device (Ethernet and ACM) 。

这个配置,在我的电脑上未出现任何USB设备。



看到这个帖子(https://whycan.cn/t_1788.html-Zero通过otg与PC共享网络)里可以改成串口配置,我就改成了Serial Gadget (with CDC ACM and CDC OBEX support) 。电脑上就出现了USB虚拟串口。

经过测试发现虚拟串口不太正常:

1. 开发板可以正常发送到PC端的串口助手:
开发板发送:

echo "125awsdQWEDFffe" > /dev/ttyGS0

2. PC端发送到开发板不正常,开发板可以接收到内容,但是PC串口助手同时也接收到了自己发送的内容:
开发板接收:

cat /dev/ttyGS0

串口助手sscom5.13显示的接收:

[20:21:54.484]收←◆125awsdffe

[20:22:04.544]收←◆125awsdQWEDFffe

[20:22:26.619]发→◇LLLK
□
[20:22:26.620]收←◆LLLK
LLLK

[20:22:31.627]发→◇LLLK
□
[20:22:31.628]收←◆LLLK

遇到的问题就是,PC串口助手发送的同时,也接收到了自己发送的内容

请问楼主用的是荔枝派zero吗,内核是哪个版本

“make menuconfig 勾选对应的 gadget 驱动程序.” ---这句话是设置kernel还是buildroot,能详细说说设置方法吗,我在buildroot里没找到gadget相关的

晕哥 说:

据说用脚本可以, 但是我只会用笨办法: https://whycan.cn/t_2448.html#p19036

流程就是, 先做一张能启动的 TF卡 : https://whycan.cn/t_561.html

然后把卡插入读卡器, 用Ubuntu Linux dd 出文件备份:

dd if=/dev/sdX of=x.bin


烧录就是执行反向操作了:

dd if=x.bin of=/dev/sdX


多谢晕哥!

原来nano制作TF卡的流程和荔枝派zero一样,回家测试。

打印这个是正常的,卡死应该是其他某个任务没法退出,查一下/etc/init.d/里面启动任务

有限制,具体限制多少还不清楚, 是 gzip 压缩的 initramfs,
Linux 最终会解压到指定内存区域作为 rootfs,
终端是 mobaxterm 的免费版.

mobaxterm 功能相当强大: https://whycan.cn/t_2057.html


多谢,果然是个强大的终端,还有免费版,哈哈

正常的,上位机不是实时的,接收数据需要自己拼帧,

实际上,stm32的接收也需要拼帧,

如果你写过可靠的串口程序,无论是上位机,还是stm32都是一样的:接收到的数据放到一个足够大的缓冲区(如环形队列等),然后从里面解析数据帧。
