xrff_z 说：

改下配置文件sys_config.fex 试试

搜索PE00
原来的可以找到
[twi2_para]
twi2_used       = 1
twi2_scl        = port:PE00<4><default><default><default>
twi2_sda        = port:PE01<4><default><default><default>

这个地方用了PE0和PE1 与uart0的冲突了，需要注释掉或者改成 twi2_used       = 0 或者全部删掉
也可能是其他端口用了PE0和PE1，搜索下同样注释掉或修改掉


谢谢,按照你得方法确实可以跑更深度的东西了

感谢解答，出现问题的具体原因暂时还位找到，  但是我发现同样的固件烧录到一块F1C200S的开发板中，奇迹竟然产生了。它。。。。。跑了。。。。，见下图

https://whycan.cn/files/members/394/F1C200S.png


猜想的原因最可能是荔枝派开发板的某些硬件和编译出的软件的某些设置不匹配，另外补充一下，我用的是mdk5.0进行编译的，经过比对很可能是内存配置出了问题

xm1994 说：

确实是lvgl的linux项目工程通过io读取的屏幕分辨率及位深

lvgl是从framebuffer读取的分辨率，而framebuffer汇报的分辨率是从内核使用的dts中panel项设置的


好的谢谢

这个问题解决了，是我的一个失误导致的

#define LV_HOR_RES_MAX (800)
#define LV_VER_RES_MAX (480)
被我写成
#define LV_HOR_RES (800)
#define LV_VER_RES (480)

然后lv_conf_checker.h文件的代码中会有如下处理

#ifndef LV_HOR_RES_MAX
#define LV_HOR_RES_MAX          (480)
#endif
#ifndef LV_VER_RES_MAX
#define LV_VER_RES_MAX          (320)
#endif

因此，每次开机都是480*320的分辨率

xm1994 说：

设备分辨率都是手动指定的，不存在自动检测这一说。所以请查阅面板的spec并正确设置分辨率。

我在Uboot里面设置了1024*600 或者800*480 都是可以开机

但是运行lvgl的时候，确实是lvgl的linux项目工程通过io读取的屏幕分辨率及位深

不知道你说指定设备分辨率是否指的是uboot设置屏幕分辨率？

关闭背光是一种处理方式，并没有解决问题，     完全处理是需要像@路漫漫的的方式，在uboot申请高位地址内存做显示缓存区，然后将地址传递给内核，不再初始化，直接延用显示

    如视频所示,在开机的试试Uboot阶段显示屏显示的LOGO挺好的，

    但是进入Kernel阶段，首先底下会出现花屏
    2.jpeg
   接着中间会出现一条线。

   请问是不是在Kernel阶段要配置一些参数?

通过以下命令加载驱动

g_audio.ko         g_ffs.ko           g_multi.ko         g_zero.ko

如文章说的那样情况，查看了我的编译环境，发现确实没有 depmod 这个命令
通过如下命令安装

sudo apt-get install module-init-tools

然后再重新执行

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- INSTALL_MOD_PATH=/opt/lichee/buildroot/output/target/  make modules_install

可以看到现在能够正常生成 modules.dep.bin, modules.dep 文件了

是这个问题吗?

这个问题是因为你的modules没有安装正确:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- INSTALL_MOD_PATH=/opt/buildroot-2019.08-hf/output/target/  make modules_install

是的，我按照这样子弄
在 /lib/modules/4.15.0-rc8-licheepi-nano+/ 会产生这个些文件

https://github.com/gentoo/eudev/blob/master/src/udev/udevadm.c
https://github.com/systemd/systemd/blob/master/src/udev/udevadm.c

找到了这两个, 在 buildroot里面开启 eudev 或 systemd, 应该都可以生成 udevadm 命令,重新打包文件系统即可.


按照你的方法，在buildroot开启了eudev方式,可以支持udevadm了
但是在 /etc/inittab 文件中添加 

ttyGS0::respawn:/bin/getty -L ttyGS0 57600 vt100

重新开机后，此时一直提示

can't open /dev/ttyGS0: No such file or directory

想使用命令

modprobe g_serial

加载起来,但发现返回错误

modprobe: can't open 'modules.dep': No such file or directory

感觉是驱动没有加载，请问要如何解决这个问题？
目前是usb的串口跟RNDIS都无法工作

在做USB复合设备的时候，参考了晕哥之前的文章
   https://www.lotlab.org/2018/07/29/record-of-using-licheepi-part-2-using-linux-gadget
   目前，usb的串口功能可以正常与板子进行交互，但是RNDIS的功能却没有成功
   开机启动的时候，在加载脚本的时候出现 /usr/bin/myusbgadget: line 41: udevadm: not found
   如图片所示
   失败图片

   我查了系统，确实没有udevadm这个程序。
   请问一下，要如何解决这个错误，让系统支持RNDIS功能
   请大家赐教，谢谢

   另外附上myusbgadget脚本的内容

如题所示，发现如果要重新烧录固件的时候，每次都要用工具短路SPI的1、4引脚，再开机
所以想请问一下，在uboot有没有一个命令可以让F1C100s重新进入usb otg的烧录模式。

按照官方的提示使用linux分支编译生成的固件
然后尝试商家编译的esp8089.ko
无法使用ismod加载该模块，提示这个ko文件版本跟我的编译分支不正确
不知道这块的模组的源代码如何跟我的编译分支搭起来
