@wuming 确认你的/lib/firmware路径有没有这个文件iwlwifi-ty-a0-gf-a0-59.ucode

@wuming 你的模组需要的固件是iwlwifi-ty-a0-gf-a0-59.ucode
sudo cp ./linux-firmware/iwlwifi* /lib/firmware

• JD bought a cheaper one
  

• The kernel code has been updated to the latest version, including the following submission records: commit 4235ffbfee944d67d14d8143762e0a9314af8ee3
  

• Compile the kernel and copy it to the device，Remember that modules.tar.gz needs to be decompressed

sudo cp ./out  /boot/firmware -R
sudo tar -zxvf ./out/modules.tar.gz -C /lib
sudo reboot

• Confirm that the network card is properly recognized，Confirm Bluetooth recognition is normal.
  
  

• Download WiFi/BT firmware

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp -rfp ./linux-firmware/iwlwifi-cc-a0* /lib/firmware/ 
sudo cp -rfp ./linux-firmware/intel /lib/firmware/ -R
sudo reboot

• Actual measurement effect
  
  

@jugg 关于I420格式的问题，环境变量增加GST_MPP_NO_RGA=0
关于黑边和数据大小不对的问题，编码器数据需要四字节对齐，比如：1920X1080 需要设置为1920X1088

Some users have been asking what kind of LCD can be compatible with the 4b machine. Due to compatibility with Raspberry Pi, the MIPI interface cannot support high resolution screens. However, the 4b machine has a DP interface, which can drive the eDP interface LCD with a simple transfer, and the software does not need to be modified. The actual debugging effect of the adapter board is as follows:

@wuming

• 编译完成out目录文件拷贝到机器/boot/firmware路径

sudo cp ./out/* /boot/firmware -R

• 解压modules.tar.gz 到机器/lib 路径

sudo tar -zxvf /boot/firmware/modules.tar.gz -C /lib

To facilitate users' development based on RKNN, the RKNN C and Python environments have been made into PPA installation sources. Running the following command can complete the installation and setup.Currently, only the ubuntu22.04 environment is supported, and other versions will be added in the future.

sudo add-apt-repository ppa:george-coolpi/rknpu
sudo apt update
sudo apt-get install rknpu2

Environmental testing

• Python

cd /usr/share/rknn-toolkit2/examples/inference_with_lite/
python3 test.py

The following results indicate that the environment was successfully built

@AugustRobot_Zou 如下图：

@Mz3D-0 The new machine will default to the WIFI&BT module of AP6275S. You can also replace other models of 1T1R modules, and there will be multiple models for users to choose from.

@jugg 那就是RGA有限制

@jugg 环境变量里边尝试关闭RGA使能。这个应该是RGB部分有限制。

@jugg GST_VIDEO_CONVERT_PREFERRED_FORMAT 环境变量改一下，I420改为默认格式。

@edwardzhou 先确认WIN是否OK，MAC暂时还没有测试，这个回头我们跟一下。

@顾真牛

@wuming

@wuming 你的内核版本不对！内核请更新到最新，使用cm5-evb-v11的配置编译

@wuming dmesg |grep iwl

@wuming 直接上传附件就好了

@AugustRobot_Zou 确认你的TTL转RS232模块使用的芯片是3.3V的还是5V的，如果是5V的可能存在漏电导致系统3.3V电压升高，进而影响EMMC正常工作。解决办法使使用3.3V的模块。

@AugustRobot_Zou 应该不是这里5V电源导致的。提供一下不能启动的串口日志。

@george WIFI固件下载链接如下 ,根据日志信息把对应firmware拷贝到机器/lib/firmware目录即可。

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

@edwardzhou 是的，这样是成功了。

@edwardzhou 默认video11

@tonyone0902 线路不变，更换颗粒，升级软件。

@wuming 驱动默认已经集成。只需要拷贝BIN文件进去。晚点发链接出来，先帮忙上传一下dmesg

@wuming 找代理商就好了，他们会安排处理。

@tonyone0902
如下命令就可以调用到jpeg硬件解码

gst-launch-1.0 v4l2src device=/dev/video22 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink  signal-fps-measurements=true sync=false

@wuming CP4B还是CM5?

@Mz3D-0 The 256G EMMC is expected to hit shelves in May.
