Hi Jakob,

I noticed on the embedded powerpc mailing list, that you are working w. linux on the Memec V2P20 FF1152 board.
I have one too and I'm given the task to get a linux up and running on it...

What kernel version are you using and where did you get the source ?. It seems to me that in the official source tree, there is only support for the Xilinx ML300 board - or am I missing something ?Montavista and MIND systems say they have a port for the memec board, but if an open source port exists, I'd prefer that.

Best regards,

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?)
