TMDX654IDKEVM: Making A53 access MCU_UART0

Heayoung Suh

Part Number: TMDX654IDKEVM

Hello

So a bit of background

From what I gathered

The R5 processor transmits and receives data trough MCU_UART0
while the A53 processor through UART0, UART1, and UART2.

so my question is it possible to to let the A53 processor transmit and receive data through the MCU_UART0 of the R5 processor?

if so which part of the PDK should be edited?

Thanks in advance!

Kind regards,
Heayoung Suh.

Dear Heayoung,

please find a FAQ for

How to switch console to a different UART instance

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/988278/faq-tda4vm-j721e-j7200-how-to-switch-console-to-a-different-uart-instance

this implementation is for J7 Devices but this can be taken as a reference for AM65x.

Hi Anshu,

Thanks for the response

will this work on a bare metal?

I am not using any OS but trying to make it work directly by editing the PDK.

Ill also add this info to my original question.

Kind regards,
Heayoung
