Hello everyone!
I seem to be promptly stuck at a place in booting (and has been for a
while now) so I figured I'd ask the list and see if anyone of you has
any ideas. This is all on a Memec Design FF1152 Rev. 3 Evaluation board
containing a XC2VP20 Virtex-II pro chip (two ppc 405GP processors).
Since the excellent Xilinx tools crash on ELF files, the only option is
to download a binary and debug using the serial port.
After enabling SERIAL_DEBUG_IO_BASE to the serial port, the last
printout is "MMU:exit()". Checking the PC and the System.map, I seem to
halt in the function __delay() which I believe is the function in
arch/ppc/kernel/misc.S since it's global. Now, I have two problems:
1. How does it get to (and get stuck in) __delay()? Can it be triggered
by some interrupt if the controller isn't properly configured or is it
called from init/main.c and there is some missing timer
(initialization)? Looking at Andrei Konovalovs ML300 setup I can't see
any external timer configured...
2. gen550_progress() (or something else) seem to be hogging the console
(serial port) one way or the other, disabling printk() and making it
much harder to debug. Any suggestions how I could deal with this? The
serial device is a generic 16550 UART (Xilinx made).
Thanks in advance!
/Jakob
(PS. Andrei: You seem to be using a DCR_INTC on your card and yet
setting the parameter USE_DCR set to 0. Why is that?)
