How to do UART3 to UART2 File transfer in STM32G0B1R8T6N

Do you mean forward datastream from one uart to another? Start with a sw fifo and byte interrupt callbacks.

UARTs can transfer bytes, they do not directly understand the concept of files. What exactly is the purpose of what you propose? Could you use the XModem protocol? Do you understand the byte level content of the files in question?
