Hello: I have a custom PPC405GPr board that I have successfully ported u-boot to.
I am now at the stage of trying to bring Linux up on the board. I have CONFIG_SERIAL_TEXT_DEBUG defined for the kernel that I am trying to bring up. I would like to have this option so I can trace through the kernel. The comments in ppc4xx_setup.c in the function serial_putc indicate that as long as the firmware (in my case u-boot) has been initialized properly, then this function should work. I have verified the addresses that the function is trying to write to and they are correct. However, when serial_putc calls the first readb, I get an exception. Can someone please provide some pointers as to what might be wrong? Thanks Jerry Walden ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
