Hi,
I am porting u-boot 1.1.1 on a new board. The board is arm920t based and it's UART port is compatible with ns16550.c so I changed the serial driver (serial.c) on the cpu/arm920t directory with the serial driver + ns16650 module available in the drivers directory. I am using bdi2k for debugging and I have initialized the UART port on the bdi2k config. The problem is that when the initialization routine in armboot_start calls serial_init of the ns16550, there are no messages, i.e. no prompt, on my serial console. When I remove the serial_init on the list of initialization functions of armboot_start, a prompt appears. I can successfully type help, and do other stuff. Whenever I try to remove the initialization routine on my BDI2k configuration and put back the serial_init function on the initialization list, I am not getting any messages on my serial console.
What could be the cause of this problem? The initialization routine on the bdi2k and serial_init are almost the same (i tried to make the sequence and the values exactly the same but I get the same result) but there are no messages displayed on my console. =(
Thank you very much for your help.
Best Regards,
Rodel Miguel
