Linux booting problem on Xilinx ppc

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:

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!

Hi Grant,

Thank you so much for the reply! Fortunately I got it work now -- it's
the crosstool compiler problem. Originally I was using gcc-4.1.0, yet when
compiling kernel 2.6.22, I noticed that it says gcc-4.1.0 will miscompile the kernel, so I changed to another version, and now I can let it go!

Right now still not fully booted because of the SystemACE problem, or
maybe the partition is not correct. I'm still working on it, hopefully to get it solved soon :-)

Thanks,

I noticed this problem happens when on-chip memories are enabled in a design
(it is 4th page in base system builder). Try to leave them "none" for both instruction and data.

The on-chip memories are disabled. Only the BRAM is enabled. Now, we also use the ELDK 4.1 from Denx and the included cross compiler. The result is the same... the Kernel stops at "Now booting the kernel". Now, we also have an USB JTAG cable. So, we can debug the memory.
Probably, anyone has another idea.

There are two common reasons for this behaviour:
1. kernel crashes before the console is configured
2. the console is not configured correctly.

In both cases; finding a way to look at __log_buf is the fastest way to figure out what is going on.

Woah. Grant's [good] advise notwithstanding, I'm confused

In both cases; finding a way to look at __log_buf is the fastest way to figure out what is going on.

I was able to look at the __log_buf variable with the JTAG cable. So, I recognized that the kernel doesn't halt after the "No booting the kernel" message. There are many output messages in the __log_buf variable until it stops at with a "Kernel panic" because the rootfs is not found (but this is the minor problem).
Now, I know that the kernel boots but I don't get an output with my Xilinx UartLite module. Are there some kernel modules which must be activated?? Btw. I have used the Linux-2.6-virtex kernel from
http://git.secretlab.ca/git/ and another Kernel (2.6.23 from kernel.org) - both with the same result.

Typo! :-)

Try "ttyUL0"
