请问，这个tina 3是啥

官方的linux bsp

能分享一下bsp链接吗？git clone太慢了

你先把MP4 解码到 YUV 文件, 再把这个YUV文件在电脑播放, 看是否正常.

最近还研究了一下f1c100s的音频，我的系统是4.15，这个是不是代表声卡驱动已经安装了。
https://whycan.cn/files/members/1315/none.png
如果4.15有驱动那之后的版本应该带了驱动，只是没有安装alsa库。你可以这样试下有没有声音cat /dev/dsp > /dev/dsp,如果有沙沙声代表驱动已经安装。

隐藏了什么?

晕哥 说：

可能还要改Makefile 或者别的文件

改下kconfig和makefile放水水哥的4.15内核sound/soc/sunxi中，不生成.o文件，menuconfig已选为Y

司徒miyoo当时的仓库备份， 仅供参考: https://github.com/qq516333132/f1c500s_kernel/

晕， 原来司徒自己撸了一套:
https://github.com/qq516333132/f1c500s_kernel/tree/master/sound/soc/suniv

https://github.com/qq516333132/f1c500s_kernel/blob/master/sound/soc/suniv/miyoo.c

使用的4.15内核，参考chonghttps://whycan.cn/t_1672.html大神的.config文件配置，https://whycan.cn/files/members/1833/IMG_20190905_095554.jpeg，但是测量荔枝派的HPL，HPR只有高电平，有大大知道荔枝派的音频参考吗

我测试过是一样可以用。
不能识别是什么情况， Linux不识别， 还是不能启动。

再次用@chong提供的内核编译一次

当中0.91秒那段日志和@chong大神的有90%的相似度

加载g_ether提示信息正常，但插入pc usb口没反应，接u盘没反应

https://whycan.cn/files/members/3/QQ20180907104929.jpg

将华嵌源码下的menuconfig里的deviceXX-》Hardware Monitoring support 打开就能找到全志4i的触摸驱动了，并且能够成功编译进内核，但是/dev下无/input，问题是不是出在设备树上导致没识别，我看日志里也没有关于rtp的日志。

阿黄 说：

我是修改
#define SUN4I_TP_EN(x)    ((x) << 5)
#define SUN4I_TP_DUAL_EN(x)    ((x) << 6)
#define SUN4I_TP_CALI_EN(x)    ((x) << 7)

并且
        reg |= SUN4I_TP_EN(1);
        reg |= TP_MODE_EN(0);
        reg |= ADC_CHAN_SELECT(2);

OK

完全正确

不用修改Makefile, 只要在 menuconfig 配置即可。
