@navik I2c没通，检查地址，硬件引脚配置

@skrlou 在 移植RTL8822CS模组 wlan0加载不出来 中说：

61dc175c-533c-498f-baf4-ddca7fd7d3cb-图片.png
模组是用的sdio接口，板子背面贴了一块8733bs模组 已经调通了 都正常了

现在把这个8733bs模组拆下来 正面贴了8822cs模组 原理图上硬件引脚都是一样的 同样是sdio接口

dts不用改什么东西 现在8822cs模组的蓝牙已经通了 wifi不行 这个要修改哪里啊

搞定了搞定了

我是降低DRAM的速度解决的，之前这儿是936MHz，改为672MHz。936MHz是超频

@awwwwa 使用cat shadow查看密码

但是shadow中有密码，是不是说明本来是有密码的？并且我用passwd修改密码，之后查看cat shadow 还是一样的。是为啥？

看一下屏幕dclk，是否由于dclk过高导致错误

您好，这个问题我也遇到了，我遇到的问题是udevd服务无法开启，既然这个服务都无法开启，那么肯定是不能实现自动挂载u盘的。

看一下openWRT配置，在根目录执行make menuconfig，搜索redund看看

可将已开发的相关程序放到 LinuxSDK 下的"out/t113_i/tl113-evm-emmc/longan/buildroot/target/usr/bin"路径下，重新编译打包生成系统镜像即可。

配置trecorderdemo

trecorderdemo要想正确运行，必须先进行配置，配置文件是recorder.cfg，它位于/etc/目录下。

修改recorder.cfg ;------------------------------------------------------------------------------- number_of_camera = 2 screen_width = 1024 screen_height = 600 camera_id = 0 ;------------------------------------------------------------------------------- ; 3 for cvbs sensor ; 2 for usb sensor ; 1 for raw sensor (need isp) ; 0 for yuv sensor ;------------------------------------------------------------------------------- camera_type = 3 video_enable = 1 video_width = 720 video_height = 480 video_framerate = 30 video_format = YUV420SP video_memory = MMAP video_rotation = 0 video_use_wm = 0 video_wm_pos_x = 0 video_wm_pos_y = 0 ;------------------------------------------------------------------------------- ; scale down need isp ;------------------------------------------------------------------------------- video_scale_down_enable = 0 video_sub_width = video_sub_height = video_buf_num = 3 audio_enable = 0 audio_format = PCM audio_channels = 2 audio_samplerate = 8000 audio_samplebits = 16 audio_bitrate = 128000 display_enable = 1 display_rect_x = 0 display_rect_y = 0 display_rect_width = 720 display_rect_height = 480 ;------------------------------------------------------------------------------- ; 0 ZORDER_TOP ; 1 ZORDER_MIDDLE ; 2 ZORDER_BOTTOM ;------------------------------------------------------------------------------- display_zorder = 0 ;------------------------------------------------------------------------------- ; 0 ROTATION_ANGLE_0 ; 1 ROTATION_ANGLE_90 ; 2 ROTATION_ANGLE_180 ; 3 ROTATION_ANGLE_270 ;------------------------------------------------------------------------------- display_rotation = 0

主要修改如下：

8ccee726-9ce2-4eee-8d59-f92e6e69251b-image.png

画红框的参数说明如下:

screen_width = 1024/screen_height = 600，表示显示屏的参数，比如演示时的屏幕分辨率是1024x600。

camera_id = 0，这个参数很重要。务必是0。trecorderdemo程序不是专门为tvin演示编写的，而是为主板可以接的各种camera，例如符合UVC协议的usb camera等。trecorderdemo程序中只能显示两路camera，一路是/dev/video0,另外一路是/dev/video1,在程序中分别对应的是front camera，另外一个对应的是back camera,见下图：

root@TinaLinux:/dev# trecorderdemo --help **************************************************************************** * This program shows how to test trecorder **************************************************************************** **************************************************************************** * trecorderdemo 0: front channel recorder test * trecorderdemo 1: rear channel recorder test * trecorderdemo 2: front and rear two channel recorder test * trecorderdemo audio X: audio X recording test(X = 0/1) *************************************************************************** root@TinaLinux:/dev# trecorderdemo --help **************************************************************************** * This program shows how to test trecorder **************************************************************************** **************************************************************************** * trecorderdemo 0: front channel recorder test * trecorderdemo 1: rear channel recorder test * trecorderdemo 2: front and rear two channel recorder test * trecorderdemo audio X: audio X recording test(X = 0/1) *************************************************************************** root@TinaLinux:/dev# trecorderdemo --help **************************************************************************** * This program shows how to test trecorder **************************************************************************** **************************************************************************** * trecorderdemo 0: front channel recorder test * trecorderdemo 1: rear channel recorder test * trecorderdemo 2: front and rear two channel recorder test * trecorderdemo audio X: audio X recording test(X = 0/1) *************************************************************************** root@TinaLinux:/dev# trecorderdemo --help **************************************************************************** * This program shows how to test trecorder **************************************************************************** **************************************************************************** * trecorderdemo 0: front channel recorder test * trecorderdemo 1: rear channel recorder test * trecorderdemo 2: front and rear two channel recorder test * trecorderdemo audio X: audio X recording test(X = 0/1) *************************************************************************** root@TinaLinux:/dev# trecorderdemo --help **************************************************************************** * This program shows how to test trecorder **************************************************************************** **************************************************************************** * trecorderdemo 0: front channel recorder test * trecorderdemo 1: rear channel recorder test * trecorderdemo 2: front and rear two channel recorder test * trecorderdemo audio X: audio X recording test(X = 0/1)

列表camera_type，这个参数是确认摄像头的类型，如果是T113的TVIN接口的摄像头，选择3（cvbs sensor）；如果是USB接口的摄像头，选择2（usb sensor）；如果是处理器内部带了ISP了，那么一般会使用raw sensor,这个时候选择1。

列表video_width/video_height，这两个参数是明确视频的分辨率，本次测试的摄像头是NTSC格式的，那么它的分辨率是720x480。

列表video_format=YUV420SP，在用camerademo调试摄像头的时候，会给出这个参数。对应的是output_fmt=YUV420;

列表display_rect_width/display_rect_height，这两个参数表示在屏幕上显示时的视频框的大小。我们一般会设置和video_width/video_height一样。

trecorderdemo演示

演示时，务必把摄像头先接好，如果未接摄像头，程序会处于假死状态，因为无法识别到摄像头。执行trecorderdemo前，务必先执行fbinit进行清屏。具体演示步骤如下：

fbinit trecorderdemo 0

这个写的太详细了，感谢分享

@wayneyao 也是一种方法，但限制是bit要8的倍数才行

@dingzhen make -j1 V=s 打开debug信息再重新上传错误log

@gwx123

就dts 可能有問題

如果你都確定其他版本可以正確
表示在那個版本的軟硬件設定正確

那事情就簡單了　就是Android 12 設定不正確

@yixintai its the lpi-3h board it has the normal AIC8800 baked in but there is a second wifi module on host board. Really its a cool looking project but so underdeveloped that while I am looking for a corporate solution it may not fit needs due to ambiguous notes and docs. I just need to flesh out the ui in android and strip out some of the issues. I just do want to spend days creating configs if someone has a quick answer. As for Corprate or Hobbyist the answer is both. working on a corprate solution but also do a fair amount of teaching my kids haw to make cool stuff like robots powered by Ai but this project is for work. and yes I know an A133 type board would be best but the the dev boards for them are so limited and the sellers are not cool with sharing bsp with US devs. and I have allwinnertech account but everything is not user friendly. We have to mail in our NDAs and they make it really complicated for poeple who dont live mainland to develop. (I love them and hate them at same time) .

可以在APST下载

@ylyamin 在 R-01 library for small OS 中说：

Since LCD RGB is working, DE probably working fine. So what is left could be LCD MIPI part.

Allwinner tends to use the same code everywhere, so there could be a problem to find alternatives. Mainline Linux kernel maybe the only place to look at. Also logic analyzer maybe needed for this kind of task.

Another reference could be xboot project: https://github.com/xboot/xboot , but seems main activities goes into LCD RGB.

@awwwwa 好的 感谢👍

问题已解决 我是在其他板级demo下复制的fw_env.cfg文件，里面有个注释掉的
#Allwinner Tina
#/dev/by-name/env 0x0000 0x20000
#/dev/by-name/env-redund 0x0000 0x20000
这个是与文档一致的 但是寻找不到MTD消息，在更改fw_env.cfg文件几次后cat /etc/fw_env.config文件发现这个并没有被更改，正确的写法应该和demo里面一致
#Allwinner Tina UBI volume
/dev/ubi0:env 0x0 0x20000 0x20000
/dev/ubi0:env-redund 0x0 0x20000 0x20000
图片传不上，先这样

@awwwwa 谢谢

真麻烦啊 几天能升级LV2
