Tool/software:
Hi,
I want to change the MCU UART port pins on our custom board, I want to use in the MCU UART port for flashing, logging and for Linux OS.
I need pins that aren't used as bootmode.
Can you tell me please which pins I can use for MCU UART?
Thanks,
Rachel
Hi,
Can we change the default MCU UART pins from J37,K38 to other pins?
Yes, If you look at the TD.
Three terminations has provided to MCU UART TXD & RXD pins.
Any of above can be used to route UART data.

Hi,
How the TDA knows which pins are for MCU UART in power on?
In case of MCU Boot Mode, you are suppose to use Pins specific in Boot Mode from TRM.
So, you have to use J37, K38 Pins only for UART Boot Mode.
In applications you can use any as per your requirement, but in case of boot mode you are suppose to use above only as ROM code is fixed and can't be changed.
Best Regards,
Sudheer
