Change ROM boot USART6 pins?

DMårt

I have a STM32MP257 custom board and I'm listening on UART6.

When I boot, I get nothing. No messages or other text. I have not yet implemented any Linux onto my SD-card.

The issue is that I have my USART6 boot pins on PF13 and PF14, instead of PF4 and PF5. Are there any way to change this in ROM?

Or do I need to load TF-A from my SD-card so TF-A can change USART6 pins?
