Tool/software:

Hi, TI expert!

I have a development environment for am6234, with our own evaluation board.

The software SDK version is PROCESSOR-SDK-LINUX-RT-AM62X-08.06.00.42.

May I ask if it is possible to use the serial port of A53 core in R5 core?

For example, I want to run the firmware generated by compiling the MCU SDK in the R5 core, using the main_uart0 serial port of the A53 core in the firmware，as shown in the above figure.

If possible, where can I find the corresponding instructions？

Hi Li,

Yes it is possible. Basically you want to redirect the logs of MAIN UART0 from A53 to R5F application, correct?

So one thing we can do is redirect the logs which were coming in UART0 to another UART port, let's say UART2, and then in UART0 have the logs of R5F core.

Please see this thread which talks about the same: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1295252/am623-changing-console-from-uart0-to-uart2

Let me know if this resolves your issue.

Regards,

Vaibhav
