@顾真牛 onedrive有CM5 TF卡的固件

@顾真牛 1080P的。

@haiting2022 如果需要通过命令行拨号方式上网，更新一下附件驱动。v5.10.11.zip

@haiting2022 参考下面文件先配置，默认5G会生成一个网卡节点。

@spartan50416 Thank you very much for your support.

@spartan50416 Sorry, to clarify, the method of making our startup disk is the same as the raspberry pie, not the firmware. Of course, the main difference is in the kernel part. If you are interested in porting the raspberry pie file system to CP4, there is no problem. You can use the PWM interface to adjust the fan speed. Our DTS configuration already supports this. The 2X20 expansion port has multiple PWM interfaces.

@spartan50416 I think there is no problem implementing the functionality in the link. If you have any questions during the modification, you can post them in the community and we will respond in a timely manner. We believe that using our machine modifications can achieve better performance.

@spartan50416 As shown in the figure below, the CP4 can have a separate fan heat sink, with EMMC, TF-card, and USB interfaces stored. The USB 3.0 interface can expand SSDs or mechanical hard disks. The machine has independent on-off buttons, which can be customized by modifying software, or external keyboards can be extended through the ADC interface. Firmware upgrades are the same as raspberry pi. You can use the balena Etcher tool to create a startup disk, and the startup media can be a TF card, a USB flash drive, or an EMMC.

@tonyone0902 显示异常的时候，打印一下下面两个命令，结果发上来：
sudo cat /sys/kernel/debug/dri/0/summary
sudo cat /sys/kernel/debug/dw-hdmi0/status

@tonyone0902 数据格式的问题可能性比较大。

@xingzhan2012 声卡选到耳机输出

The CM5-evb board has two native eDP interfaces, designed according to the standard 30PIN eDP interface, and can directly drive an eDP LCD without any conversion. Interface integrated backlight control circuit. LCD backlight brightness adjustment can be achieved.

@allen 看看内核部分是否确认一些配置。自己加上更新一下。

@xingzhan2012 四月初各个店铺上架。

@lej40 said in Type c power port:

Is the the type-c PD port also a USB-c data port

Sorry,This port is used for power supply and has no data connection.

@tonyone0902 如下图所示，板子的BOTTOM面有测试点，可以焊接外部电源。

机器本身不具备电量侦测功能，可以外加库仑计通过I2C接口。

@tonyone0902 最低输入电压5V，所以并联是不行的，串联12V从TYPEC输入没有问题。
