(Sorry if this is a dupe, but I think my first attempt was filtered out) Hi,
I'm trying to get Linux booting on a custom board based on the MPC8313 ERDB, but there's no output after the console is transferred. I get the following: Using MPC831x RDB machine description Linux version 2.6.29 (mlcre...@lap) (gcc version 4.3.2 (Sourcery G++ Lite 4.3-50 ) ) #2 PREEMPT Tue Mar 31 14:54:27 EDT 2009 console [udbg0] enabled ... (normal boot output) ... Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled serial8250.0: ttyS0 at MMIO 0xe0004500 (irq = 16) is a 16550A console handover: boot [udbg0] -> real [ttyS0] serial8250.0: ttyS1 at MMIO 0xe0004600 (irq = 17) is a 16550A If I boot with "console=udbg0,115200", then it gets much further along before printing "turn off boot console udbg0". So presumably the kernel is booting beyond this point, but my console isn't printing any output. I traced from that last line back up the call stack to the end of drivers/serial/8250.c:serial8250_init(), and everything seems okay (it returns 0, and pritnk() still works fine at that point). I'm not sure where to go from there to figure out where the problem lies. Could someone point me in the right direction, or suggest what might cause a console problem like this? Thanks! -- Matthew L.
