We've booted the first kernel on the hardware with Flash, and that works fine. So the hardware doesn't seem to be the problem. We have a JTAG port, debugging and viewing the log_buf address after the crash just gave us 8 zero's so no usefull hints there.. The kernel probably crashes before it can write anything to that buffer, or before its initialized?
I'll also include the output we get here, maybe its helpfull: loaded at: 00400000 004A11E0 board data at: 0049E138 0049E150 relocated to: 004052D4 004052EC zimage at: 0040589F 0049D91C avail ram: 004A2000 02000000 Linux/PPC load: root=/dev/nfs rw ip=on Uncompressing Linux...done. Now booting the kernel And then it halts.. Any other suggestions would be welcome :) Regards Sander ----- Original Message ----- From: "Peter Ryser" <[EMAIL PROTECTED]> To: "S. van Beek" <nlv11891 at prle> Cc: <Linuxppc-embedded at ozlabs.org> Sent: Thursday 17 March 2005 19:04 Subject: Re: Problems with MontaVista Linux on a Memec Virtex-II pro ff672 board > Also try to boot the first Linux kernel (the one without the Flash > support) on the EDK design with Flash support.
