davemf:

Is UART0 activated on android 10 source? Which port is used? ttyS0? I need to connect GPS receiver.
Is UART1 used for Linux logs? Is it ttyFIQ0?

In addition, read and write permission for this serial port is required： chmod 777 /dev/ttyS2 uart tool test download [image] [image] [image] [image]
