IMX8QM MEK use second uart

josemartins90 — Sat, 08 Aug 2020 16:01:14 GMT

I'm using an IMX8QM MEK board. From the cortex-a complex, I use lpuart0 to print. I'd like to use a second uart from the same set of cores to print using the available USB. Is this possible? Thank you in advance....

Hi josemartins90

seems lpuart2 is used for M4 core, one can try to move it to A-cores partition

using example with FlexCan on:

And are you sure this uart is accessible through the USB like lpuart0?
