Can I remap the flash UART0 to some other I/O's other than PIN34 and PIN35?

It was a mistake on my prototype.
I used PIN34 and PIN35 for something else. Right now I am developing software on the first round of prototype.
I will change it in the next round of prototype.
But with what I have, can I reconfig the UART0 to some other unused PINS. I can just solder the flash programmer RXD/TXD to those unused I/Os.
Trying to avoid cutting the traces on the PCB.

Thanks
Paul

There is an option in menuconfig to change UART0 TX/RX pins. But I am not 100% sure if that is just for the console only.
You can give it a try.

OK, Thanks.
Will give it a try later.
