About i.MX6Q-SD Board UARTs test

Hi,

Greetings

I have a question about i.MX6Q-SD board UARTs, the system version i used is Android 4.4.3_2.0.0. There are almost 5 UART modules on this board, and UART1 is used to output the whole system log. I wanna use UART2, UART3, UART4 to communicate with my PC(I have CH340 serial module on my PC), so should i write linux driver and add the nodes to DTS file? Or just open it?

Thanks,

Hi albert_zhang

as Android 4.4.3_2.0.0 is based on L3.10.53 kernel one can try to enable uarts in

corresponding dts file:

linux/arch/arm/boot/dts/imx6qdl.dtsi

imx6qdl.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel 

Best regards
igor
