@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。

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.

@Mz3D-0 Yes, 256 G EMMC can be supported

1.设备树里边把不需要的模块可以disabled掉。
2.AI算法使用RKNN处理，尽量不直接用CPU跑.
3.应用层图像数据拷贝和格式转换使用RGA硬件模块实现，能效比高很多。
4.如果是USB摄像头，MJPG解码使用rkmpp硬件解码。

Coolpi supports UMS to update emmc firmware, as follows:

1. Update the latest versions of loader and uboot images. You can also synchronize uboot code and compile it yourself.

git clone https://github.com/yanyitech/coolpi-loader
cd coolpi-loader
./build-uboot.sh cp4b

2. Connect a dual A port USB cable to the computer and the upper USB 3.0 interface. Plug in the power and press the power button three times, and the machine will enter UMS mode.
   
3. Use Etcher software to update the software.
   

Through the continuous efforts of engineers, coolpi can perfectly support 32GB LPDDR4/4X memory. There is better support for AI large models and server scenarios. The 32GB version of the 4b machine will be officially released in May. Thank you for your support.

Clock rate up to 2112M, data rate 4224M.

@Mz3D-0

1. Can support mesa GPU driver, compatible with X11 WAYLAND
2. Currently maximum 128 G, more than 128 G need to be customized, such as 256 G.

@Mz3D-0 You can purchase the CP4B official radiator kit from the agent

@wuming 能否识别maskrom，如果不行就联系代理商。

@wuming 尝试是否能正常识别maskrom，按住loader按键再上电。USB线连接电脑。

Wiki provides the information of each product download, will be further improved in the future, thank you for your support.

@顾真牛 改为动态分频测试一下

@顾真牛 插拔HDMI然后打印dmesg发上来。

DRM 框架目前代码已经支持了绝大部分分辨率时序，但是部分 HDMI 屏幕旋转的场景下，可能还有一些特殊分辨率不支持。需要在 kernel\drivers\gpu\drm\drm_edid.c 中的drm_dmt_modes 的末尾新增项目：

/* 0x58 - 4096x2160@59.94Hz RB */
{ DRM_MODE("4096x2160", DRM_MODE_TYPE_DRIVER, 556188, 4096, 4104,
4136, 4176, 0, 2160, 2208, 2216, 2222, 0,
DRM_MODE_FLAG_PHSYNC | DRM_MODE_FLAG_NVSYNC) },

@likeshixi 提供插拔HDMI的dmesg信息

@顾真牛 下周发布底板的设计资料。

@顾真牛 uboot 和kernel 搜索edid.c 有个白名单把你的分辨率加进去 static const struct base_drm_display_mode resolution_white[]
