imx93 UART DEBUG

[michaelscott2371]

Hey, im designing an hardware board that features the imx93.

i have two imx93 on the board.

i want to connect uart debug through FTDI to the arm cpus but because of some other elements i have on the board, i will need to use 2 FTDI's to connect uart debug to both a55 and m33 cpus.

is it possible to debug the m33 through the a55 and connect only the uart to a55?

Hi,

Thank you for your interest in NXP Semiconductor products,

I think that the best alternative would be to debug Cortex-M terminal through Cortex-A terminal, you could do it through the usage of RPMSG framework, so instead of sending them through normal UART, you should base your debug system in the multicore examples (using RPMSG framework) it would send the debug strings and you would print those strings through Cortex-A managed UART.
