Hello there,

This is our first post on this list, hi all!
We're two Dutch students working with a Virtex-II pro ff672 board from Memec with the Communications 2 module. We've compiled a simple kernel wich comes with MontaVista Linux 3.1 (2.4.20) with ethernet and a serial port. It mounts its root filesystem over NFS and everything seems to work nicely. The next step we wanted to make was adding support for the Flash on the com board. We added the IP to the hardware and loaded the new bitstream in the FPGA. Next thing, we enabled support for MTD devices in the kernel. After that, the kernel did not seem to boot anymore. It stopped at the message 'Now booting the kernel'. So we read some documentation about debugging. We recompiled this kernel with the -g -ggdb options and removed the -O (optimalization) flag. Then we did not even see the ppc boot loader messages anymore when trying to boot. So we tried to compile the first kernel (with only serial and ethernet support) -wich worked fine before- with debugging and it gave us the same result.. no output at all. 
Can anyone give us some hints on what we can try more to find out what is going wrong? 

Regards,
