@edwardzhou 用U盘备份安装系统，不用考虑移除emmc

@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。

我已经发现了会独占屏幕 锁屏了图像还在。。

@lej40 The DP interface cannot be configured as a USB3.1 interface. If two USB3.1 interfaces are not enough, it can be extended by using an external USB HUB. Two USB2.0 connectors are reserved on the back of the CP4 machine for users to use.

@george

Thanks!

@retroman Has been updated, please check.

@大法师 Many thanks for your reply, but unoccupied serial ports accessible from GPIOs include uart3,6. There left only uart6 if uart3 can't be functional. Is it possible to activate uart3-m2-xfer?
