小明第一次去超市买猪肉，以前没吃过这个猪肉
猪肉30块一斤
小明说，哇，猪肉好贵啊，老板你长得好难看啊，滚出去不能在这家超市卖猪肉，滚出去不能在超市门口宣传，东北的鸡肉比你的便宜，美国的鸭肉也便宜，你要降低你卖猪肉的价格到10块一斤。还有啊，你的猪肉也好难吃啊
老板说，哈哈，小伙子，要不你也去养一头猪或者买一头猪回来宰了卖大家10块一斤吧
小明说，我不管，你又难看，肉又贵又难吃

说话都得分场合，何况这种商业行径。
表错情?大讲特讲搞生态是一厢情愿?那这种跑来社区搞推广就是真理?我应该鼓掌欢迎?
我可不认为在社区大讲特讲搞生态有什么丢人。反而搞这种与社区理念相悖的商业行径的人觉得自己很高尚。

novice 说：

楼主是全志芯片代理商，说不定还代理其他公司的芯片呢，这里有些人一厢情愿的跟代理商说搞生态？表错情了吧？
全志一直都是走大客户路线，根本就不鸟散客，台湾和大陆的芯片厂商大都走这条路线。

checkout · 全志 SOC

我认为，在社区推广这种远高于市面同类开发板的行为，完全和社区的开源分享理念相悖。直白一点，就好比你在清真餐厅吃猪肉包，你到别的地方怎么吃都没人有意见，但在这里就不一样。我抬杠的是这种行径，明白?
我个人不违反社区规则和理念的前提下，我白嫖有什么问题？
社区的理念不就是分享吗？
难不成你没白嫖过社区的资源?
要是说，这家代理商公司是有出钱支持晕哥的论坛来打广告的，我对这种支持社区的行为是表示欢迎和感谢的。

Blueskull 说：

没记错的话这家卖板子的自己封的X3吧，某种意义上这款芯片是人家自己开发的，人家自己的芯片放出来什么资料，怎么放出来，先给谁后给谁，人家自己说了算吧。
不喜欢的话你也可以自己去找全志买A33裸片自己封SiP。
何况，因为die是A33，就算X3原厂不提供BSP，你买几个芯片要个pin脚图和内存时序，还不是可以直接套用A33的BSP？
既然有别的路可以走，那么你真的感兴趣，愿意玩的话人家卖多少钱就不影响你了。
至于说你想白嫖原厂BSP还想快速商业开发，一点都不想贡献sunxi社区，那就是你的不对了。你说我这话讲理不？

checkout · 全志 SOC

1.没错，我是要感谢第一批吃螃蟹的人，包括大家。3352买的贵是人家有底气，国内买的便宜是造福大众，应该感谢。
2.我可没吐槽全志，全志对社区的支持力度还是很友好的，反过来，社区也很乐意使用全志的芯片，例如sunxi社区，两者是相辅相成的。这一点你可不要以偏概全。我是吐槽这种对看不出有什么友好态度和贡献行为的，却跑来社区做商业推广的公司。
3.你动不动就说"________"，"___"之类的，因何说出这种话呢？大清都亡了这么多年，这点自信怎么都没有呢？

Blueskull 说：

没有第一批吃螃蟹的出钱你永远拿不到BSP。得便宜还要卖乖。说句不好听的，没有金主推动支持，这种复杂的多核SoC你连start.S都写不出来。

AM3358多少钱？对标的单核全志A13多少钱？

就是看不惯白嫖有理怪。

除了Beagle全世界没有比全志资料更好找的MPU了吧。Microchip确实有A5的SAM系列，STM也有A7的MP系列，我咋没看到有人用？我承认谁优秀？
不如现在的优秀，我凭啥捧着它？号称开源社区最大的RPi系列连个电路图都没有，芯片也买不到，没见某些牧羊犬去婊。

checkout · 全志 SOC

是是是，就是国内芯片厂商惯坏了我这种白嫖怪。但我就是乐意抬杠。乐意和这种完全看不出有什么友好态度或贡献行为，却利用开源社区这个平台做商业推广的公司抬杠。TI和飞思卡尔官方开发板买的贵是事实，但人家脸皮没那么厚来开源社区推广，何况beaglebone系列开发板的推广和对社区的支持力度有目共睹。我吐槽的原因是这个，至于你为什么要捧它们，我倒是很好奇。
此外，吐槽国内公司不好就说是捧洋大人的脸，这点不敢苟同。现在这个年代，承认别人优秀没那么难吧，这点脸皮都没有?

Blueskull 说：

飞思卡尔iMX6UL系列528M主频单核A7原厂板子带屏250美金，没有技术支持，只有一个日均发帖量不过百的论坛和几个PDF教程。爱买买，不爱买别买。
TI除了给爱好者准备的Beagle系列，其他面向专业用户的ARM MPU（非MCU）板子都在300美金以上。
X3这个价格不正常？国产芯片单价便宜就算了，凭啥开发门槛还得低？卖给你已经是给你脸了。日韩台湾很多消费类芯片小批量不签NDA买都买不到，不一样大规模应用？
这个级别的4核A7就没有集成RAM的，不爱买X3可以自己开模封一个SiP。骨头贱喜欢洋大人的完善生态链的没人说你不可以买iMX6Q/iMX8或者Sitara。
没那个预算还想要人家的生态，梦里都有。你非抬杠说手机SoC有集成RAM的那我也没话说，你买得到还能搞到BSP算。

呵呵，别人都说___，难不成你不信还要试试？我就是看不惯国内这种公司的吃相，做得差还不承认，还说爱买不买。

1-提高门槛=拒绝开发者？
2-不舍得花钱又不允许宣传，真酸。
3-有看到上面说的“返还费用”？
4-“做的不好又不能允许人家骂”---有使用才有发言权，我没使用过，好用与否不做评论，用过么？
5-评论别人做的不好的时候大可自己大展身手，用X3自己搞个开发板卖100块？
6-市场供需，你需要而我刚好有，上市公司老板都会宣传自己公司产品，你们家产品是不是像光刻机大家求着你卖？

1.提高门槛，这是事实，这种策略就是拒绝个人开发者。哦，应该是拒绝不舍得花这个钱的个人开发者。
2.采用这种策略还说自己不是靠卖开发板赚钱，并且来社区打广告，这种行为说"厚颜无耻"一点也不过分。
3.国内公司采用这种策略生存无可厚非，但这种策略和行为无论在国内还是国外开源社区都是不受欢迎的，你个人没必要替他们辩解。
4.做的不好又不能允许人家骂，难哦~

公司客户，你卖2万块都不会有人喷你。但公司立项的时候，技术员肯定会优先选自己熟悉的芯片或者技术支持友好的大公司的芯片。为什么ST在国内有那么多人乐意用?价格便宜？那是因为人家生态做的好，很多开发者在大学或者入行的时候基本都玩过ST的板子，熟悉;所以，立项的时候就会考虑到这个片子。你这种公司既不想做生态，还提高门槛拒绝个人开发者，还高呼我冤枉，我不靠卖开发板赚钱，你们个人开发者不要捣乱，做公司项目的时候记得再来选我!"我从未见过有如此厚颜无耻之人"!!!这里是开发者社区，有脸来打广告，被喷也正常不过。

李某人说：

我觉得这个价格还好吧。
1-对个人开发者入门学习成本是高的
2-公司角度想用这个芯片不在乎这点钱，项目量产后大部分代理商是会返回这个开发板的钱的，开发板和收开发费都是为了大家有共同目的让项目量产
3-代理商本身不靠大批量出货开发板赚钱的，做几十套是为了方便客户前期研发
4-研发成本除了硬件，还有软件，不能只计算板子上物料的价格
5-从淘宝和其他地方买了几颗芯片自己画或者买个第三方的开发板，资料和技术支持能像代理一样好吗？我看未必吧，很多从淘宝买了便宜开发板，最后还是要找代理商做技术支持，最后量产又找其他人买，你是代理商的话能接受这样吗

所谓说，没有对比就没有伤害。群友都列举了国外厂商ST之类的推广策略如何受开发者欢迎，你再回头看看国内厂家的遮遮掩掩。你既然是想卖芯片，还是跑来开发者社区做推广，何必吃两头又不让利?打广告都是要钱的，你这变相提高普通玩家门槛又何必呢?试问有多少普通玩家出发点一开始就是从拿这个芯片来做项目?另外，我不同意"想吃螃蟹也不想花钱"的说法，开源社区核心就在于分享，大家都这么精明计较，何必来社区掺和呢?

Blueskull 说：

不知道为什么那么多人喷卖家。你不乐意就别买板子。要个原理图封装图和ddr时序参数，自己画板子呗。内核uboot啥的都可以直接套a33，这玩意除了上述那几个和a33不一样其他都一样。卖家支持的成本大头不在这些东西，在于完善的驱动和原厂bsp。你私信一下卖家，买几个芯片，还要不来手册？有了手册既然你没花bsp的钱，那就老老实实用a33的bsp，又不是没有。再说了，等卖家捞一波先期客户的钱，总有人会把bsp发出去的。又不想花钱又不想花时间，还想第一个吃螃蟹？那花钱的岂不成老实人了？

单纯判断键值貌似是区分不了大小写的。
有些键盘shift+a组合表示大写A，Caps Lock锁定大写时按单一a键也是大写A。
直接读raw数据或许准确一些，还可以判断组合键和多键同时按下的情况。

谢谢mango的回复。今天开电脑又试了试，是没问题的:D。。。估计是putty的原因，之前敲回车没反应
主要是widora官方的openwrt声卡驱动有点问题，准备试试主线的有没问题
openwrt（widora-neo）使用portaudio播放音频,出现多次调用postinit(),伴有杂音，偶尔会造成系统奔溃

mango 说：

看着问题不大，看样子敲回车应该会激活命令交互

今日翻出widora-neo开发板，试试编译主线openwrt，发现启动卡住，不能进入shell...
感觉是flash驱动的原因，不知有没大佬遇到类似情况

不是。

好想做个有钱人说：

请教 portaudio 是声音合成平台吗?

checkout · Openwrt/LEDE/AR9331/MT7688/RT5350

使用aplay和madplay播放音频都没问题的，初步怀疑问题出在portaudio初始化的时候，对声卡多次进行设置。
同一程序在其他平台都没遇到这个bug。立个贴留个坑

checkout · Openwrt/LEDE/AR9331/MT7688/RT5350

硬件：widora-neo开发板，
软件：widora官方固件Ver0.1.9-20190812
问题描述：使用portaudio播放音频流，上电第一次initialize的时候，底层驱动出现多次调用postinit()函数，伴有杂音，偶尔会造成系统奔溃。
有没大佬遇到这种情况，或者有什么idea？
现象如下：

把基本外设初始化好，再向内核传参就行，可以做到很小，启动时间主要是从flash加载内核到内存耗时比较长

胸弟，你看！！摊手.jpg
APB2默认时钟源是24MHz.你要改成PLL_PERIPH

u-boot-2011.09/arch/arm/cpu/armv7/sun8iw5/clock.c中,函数sunxi_clock_set_corepll(xxx)进行了时钟初始化...
在这里修改：

int sunxi_clock_set_corepll(int frequency, int core_vol)
{
    unsigned int reg_val;
    unsigned int i;
    struct core_pll_freq_tbl  pll_factor;
    //检查时钟是否合法,为0或者超过2G
    if(!frequency)
    {
        //默认频率
        frequency = 408;
    }
    else if(frequency < 24)
    {
		frequency = 24;
    }
    //切换到24M
    reg_val = readl(CCM_CPU_L2_AXI_CTRL);
    reg_val &= ~(0x03 << 16);
    reg_val |=  (0x01 << 16);
    writel(reg_val, CCM_CPU_L2_AXI_CTRL);
    //延时，等待时钟稳定
    for(i=0; i<0x400; i++);
    //调整时钟频率
	clk_get_pll_para(&pll_factor, frequency);
	//回写PLL1
    reg_val = readl(CCM_PLL1_CPUX_CTRL);
    reg_val &= ~((0x03 << 16) | (0x1f << 8) | (0x03 << 4) | (0x03 << 0));
	reg_val |=  (pll_factor.FactorP << 16) | (pll_factor.FactorN<<8) | (pll_factor.FactorK<<4) | (0 << 0) ;
    writel(reg_val, CCM_PLL1_CPUX_CTRL);
    //延时，等待时钟稳定
#ifndef CONFIG_A67_FPGA
	do
	{
		reg_val = readl(CCM_PLL1_CPUX_CTRL);
	}
	while(!(reg_val & (0x1 << 28)));
#endif
    //修改AXI,AHB,APB分频
    clk_set_divd();
    //切换时钟到COREPLL上
    reg_val = readl(CCM_CPU_L2_AXI_CTRL);
    reg_val &= ~(0x03 << 16);
    reg_val |=  (0x02 << 16);
    writel(reg_val, CCM_CPU_L2_AXI_CTRL);
    
    //修改apb2时钟源，自己添加。。
    return  0;
}

下面这个顺便也要改一下，改成600

        struct sunxi_ccm_reg *const ccm =
                (struct sunxi_ccm_reg *)SUNXI_CCM_BASE;

        /* uart clock source is apb2 */
        writel(APB2_CLK_SRC_OSC24M|      //这里改为APB2_CLK_SRC_PLL6，从内部pll6时钟分频
            APB2_CLK_RATE_N_1|
            APB2_CLK_RATE_M(1),
            &ccm->apb2_div);

apb2时钟默认是OSC24M,时钟源应该使用PLL6，修改uboot时钟初始化的代码就行
24000000/16/921600=1.6276，向上取整，实际波特率24000000/16/2=750000，应该是这样

这是tinyplay 打开pcm的源码

/** Opens a PCM.
 * @param card The card that the pcm belongs to.

 * @param device The device that the pcm belongs to.
 *  The default device is zero.
 * @param flags Specify characteristics and functionality about the pcm.
 *  May be a bitwise AND of the following:

按提示，加了get_pcm_error()跟踪错误信息,貌似是ioctl设置参数的时候出错

无线能不能支持ap+sta模式?

那岂不是可以做成无线中继或路由器
不知性能怎么样
是的，可以的, 这里有步奏，开启 IP 转发即可 https://www.cnblogs.com/fbwfbi/p/3633163.html
使用iptables开启本地的SNAT

经过前面几个步骤，无线网卡已经可以自动分配IP，现在只需要把无线网卡的数据都经过eth0(有线网络)发到外网去，这就需要IP转发了。
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
至此，ubuntu的WPA2-PSK的无线wifi AP设置完毕，可以正常使用了。
只是我这块荔枝派zero 板子底板没有焊, 没有有线网络, 所以没有办法现在就测试。

不是这个问题，我是拿sd卡插读卡器，接usb-host的

刷widora的官方固件两张sd卡都没问题，就是最新版本的openwrt一张sd卡拷贝不了大文件
搞不懂什么原因
我擦，大概应该可以定位到sd驱动：mtk-sd: MediaTek MT6575 MSDC Driver
你看看最新op是否有这句打印，widora固件的log： https://www.widora.io/zh/version
怕是op官方那些人又把驱动搞错了。

v3s不知道怎么配置？

嗯嗯，v3s有6个endpoint，貌似其中5个支持中断传输,每个键盘或鼠标至少申请1个中断ep，应该不能超过5个。

晕哥说：

checkout 说：
V3s也是使用musb,键盘鼠标多的旁友可以用licheepi zero试试最多能接多少个键盘或鼠标，并且能正常cat得到eventX数据的。估计不能超过5个，至多6个?
要两个 HUB 级联吧？

mark..
1 这两个帖子都提到接hub,同时连两个键盘不能使用的问题：
f1c100s USB otg device 模式可以用吗?
F1C100S 使用BSP USB转以太网，USB摄像头，USB转串口，U盘/读卡

2 估计是ep数量太少，网友类似情况：
am3352 usb can not read/write 18 hids
linux调试LTE模块驱动

3 本人测试：接hub,1个打印机，1个键盘，2个U盘，这是没问题的。同时接两个hid设备类只能用一个。
/drivers/usb/musb/musb_host.c:中musb_schedule出错，return -ENOSPC.分配不到资源

guanglun 说：

晕哥说：
有没有可能是供电引起呢？
鼠标键盘单独供电试一试.
单独都是OK的，直接插鼠标键盘都OK，单独通过hub插到f1c100s也是OK的，但是两个同时插上去就只有一个能用，另外一个看LOG是挂载上去了，但是无法使用。。
晕哥说说解决思路。。

烧写参考这里：https://whycan.cn/t_2179.html
其中，boot.scr、zImage、xx.dtb放到第一分区(FAT16)，解压rootfs.tar到第二分区(ext4)
启动到uboot,执行命令：run distro_bootcmd 加载内核
启动到shell,执行命令：sh run_adbd.sh 运行adbd

直接按照上面各位大佬的步骤patch到4.14内核是没问题的，但荔枝派官方4.14-exp版本内核有个bug，就是105楼@Peter所遇到的
填坑：修改drivers/usb/musb/sunxi.c：742行

+      of_device_is_compatible(np, "allwinner,suniv-f1c100s-musb")) {

修改后usb正常，log如下:

花了一点时间对Icenowy的patch和chong的patch进行了比较，结果发现chong的patch包基本上就是在Icenowy的基础上更改了下面的这个文件：

+ 0x0cc, BIT(1), 0);
static SUNXI_CCU_GATE(dram_ve_clk, "dram-ve", "pll-ddr",

理论上将上面这个patch应用到Icenowy的4.14内核中，USB应该也就能跑了。

@jiangming1399 我的4.14内核只修改此处，USB没办法正常运行，请问你用的哪个内核？

本帖子旨在分享本人之前在荔枝派zero板子上移植的投屏软件：scrcpy。
scrcpy投屏的分辨率与流畅度受限于两个方面：1.图形渲染 2.解码（h264）
源项目简介：https://github.com/Genymobile/scrcpy.git
大致原理：scrcpy使用adb push一个jar包到Android手机，手机作为server抓取手机屏幕并编码压缩，开发板作为client通过adb连接server；开发板接受到h264码流后解码、渲染显示。此外，client端还可以接受本地键盘和鼠标命令控制Android手机。
硬件验证：licheepi zero开发板
软件：解码与渲染都是软件方式，效果不必期待会有多好。不过，可以拿到有GPU的树莓派上跑，效果应该不错。
scrcpy需要用到adb（不是adbd!!!，所以，你懂的:p要先移植它

有点意思～
很有可能是轮詢

会不会是软切换?
系统上电默认是USB从机模式，用户插入u盘的话，在用户点击存储UI界面查看U盘内容的时候再切换为主机，主从切换的触发在这个点击按钮上。

解决了，是设备树没配置好～
官方的sun8i-v3s-licheepi-zero-dock.dts是有配置的，但sun8i-v3s-licheepi-zero.dts没有配置声卡，buildroot配置的时候使用了这个了

上面是群里小熊猫的固件启动log
下面是我自己使用zero默认配置编译出来的固件的启动log
怎么肥事，哪位大佬指点一下

zero默认配置不是配置了声卡？确实是用默认配置编译的哇。。
怎么没有的:(
哪位大佬能提供一些测试好的固件试试

配置完，一键编译后的uboot还是不能直接从sd卡启动的，需要手动配置CONFIG_BOOTCOMMAND和CONFIG_BOOTARGS参数
1.cd 你的buildroot所在根目录/output/build/uboot-v3s-spi-experimental/
2.删除.stamp_built,.stamp_images_installed,.stamp_installed
3.修改 include/configs/sun8i.h, 使u-boot可以直接从tf卡启动：

#define CONFIG_BOOTCOMMAND   "setenv bootm_boot_mode sec; " \
                            "load mmc 0:1 0x41000000 zImage; "  \
                            "load mmc 0:1 0x41800000 sun8i-v3s-licheepi-zero-dock.dtb; " \
                            "bootz 0x41000000 - 0x41800000;"

#define CONFIG_BOOTARGS      "console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw  vt.global_cursor_default=0"

4.在回到builroot根目录，再次make
5.在output/images目录可以得到uboot.bin,xxx.dtb,zimage和rootfs.tar
6. 烧录TF卡启动盘:
参考搬运：荔枝派Zero V3s开发板入坑记录 (TF/SD卡启动)(主线Linux,主线u-boot)

1) 删除TF卡所有分区
2) 将uboot写入到sd卡8k偏移处(必须8K偏移, brom龟腚的)。
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
3) 建立第一个分区,大小32M(可以随意填写), 格式FAT16, 把zImage, sun8i-v3s-licheepi-zero.dtb拷贝到这个分区
4) 建立第二个分区，用尽剩余空间,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
tar xvf output/images/rootfs.tar -C /挂载的tf卡第二个分区目录

附 log如下：

第一次发帖，先写这么多了:D

checkout · 全志 SOC

本人的开发环境是vmware workstation 15 pro+ubuntu 16.04_x64
参照沉鱼的帖子荔枝派Zero V3s开发板入坑记录 (TF/SD卡启动)(主线Linux,主线u-boot)
做如下配置：
1.target options配置

2.kernel配置
使用licheepi官方git代码库linux-4.13.y分支
使用licheepi_zero_deconfig配置（可在内核文件夹arch/arm/configs/下找到）
使用sun8i-v3s-licheepi-zero.dts，生成dtb（可在内核文件夹arch/arm/boot/dts/下找到）

3.uboot配置
使用Kconfig构建（新版本都是使用Kconfig）
使用licheepi官方git代码库ubootuboot v3s-spi-experimental分支
使用licheepi官方uboot里面的LicheePi_Zero_defconfig

4.Toolchain配置
使用buildroot工具链
kernel header配置成same as kernel being built
custom kernel headers series配置成相应的4.13.x版本（可在内核文件夹根目录Makefile文件中查看相应内核版本）
其他项默认即可，如默认编译uClibc, 开启MMU等

5.其余项配置，可按需配置
Build options,默认配置
System configuration
-/dev managerment,选择dynamic using devtmpfs+mdev
Target packages,各种第三方软件包，默认配置
Filesystem images,默认是tar
Host utilities,默认配置
Legacy config options，默认配置

保存配置，执行make，由于buildroot版本较新，可能对系统软件个别依赖包版本较高，可在编译前sudo apt-get update,再sudo apt-get upgrade

checkout · 全志 SOC

开贴记录配置最新buildroot-2018.08.使用buildroot自带工具链一键编译生成uboot,kernel,dtb和rootfs.
最新稳定版buildroot下载：buildroot-2018.08.02稳定版
我配置好的config文件：配置好的.config

checkout · 全志 SOC

为什么不配置builroot一键生成uboot,kernel和rootfs？
