I have enabled both UART0 and UART 1 using the CONFIG_SERIAL_MULTI in my board specific header file. The board is based on PPC 440GX processor. I used the serial1_puts and serial1_getc to access the UART1 but without access. Does anybody have used this functions before?

Yes, this was tested successfully on multiple 4xx platforms. I don't remember testing it on a 440GX though. Could be that the pin multiplexing is not initialized correctly. Please recheck that the GPIO configuration and the PFC registers are setup correctly for UART1.

Best regards, Stefan
