Dear team,

My customer would like to use UART3 on the iMX8M Plus EVK, can you advise if the customer would like the use UART3 on J21 if he needs to change something in the device tree.

BTW, he still wants to debug via the USB port but he wants to add external UART communicate 

Waiting for your kind feedback, Thanks in advance

B.Regards,

Shai

@Qmiller,

Thanks for the input, it works out of the box as you said.

Just noting, you should enable UART3 for all imx8m EVK for example the EVK of the imx8m mini/nano does not come with UART3 enabled in the DTS and I think it should be enabled.

KR,

Shai
