Dear friends,
I'm trying to run Linux in AvNet (Memec) Xilinx-XC2VP50-EVKT-FF1152
board. The Linux version I'm using is 2.4; the cross-compiler is
gcc-4.1.0, glibc 2.3.6. When booting the kernel, it shows:
loaded at: 00400000 004B51E4
board data at: 00000000 00000018
relocated to: 0040526C 00405284
zimage at: 00405B2B 004B177C
avail ram: 004B6000 60000000
Linux/PPC load: console=ttyS0,9600 root=/dev/xsysace/disc0/part3 rw
Uncompressing Linux...done.
Now booting the kernel
Then it hangs. First it seems to me that the "avail ram" is not correct,
since I configured only 32MB SDRAM. Moreover, if it's first powered on, the
end address of "avail ram" would be FFD9FBED. Then I tried to investigate
the problem using xmd. When launched, it says:

Then I download the Linux kernel using dow, and the following message
appears:
WARNING: Attempted to read location: 0xfffffffc. Reading ISOCM memory

After typing "run" command, the following appears:
PC reset to 0x00400000, Clearing MSR Register
Processor started. Type "stop" to stop processor
Then after issuing "stop", it says "unable to stop processor"
I also tried kernel version 2.6.22, but the same thing happens, except that
the "avail ram" changed to 7C9E2378 and it's the same no matter first
powered on or not.
No idea how to continue...
Could somebody give me some help? Thanks!
