IMX8M Mini A53 core UART debug

suhas_mv — Sun, 04 Oct 2020 20:29:48 GMT

Hi,

We are using i.MX8M mini (MIMX8MM3CVTKZAA) in our design, when referred to i.MX8M mini EVK schematics (SPF-31399_C2), UART 2 is used for A53 debug and UART 4 is used for M4 debug, is it mandatory to use the same UART's for A53 debug and M4 debug? Is it possible to move the debug ports to other UART's (i.e. UART 1 and UART 3)?

Regards,

Suhas

Hi suhas_mv

in general yes - it is possible to move the debug ports to other UART's

Software changes may be performed for console (uart2) in dts
