In house we use the gcc 4.1.2, glibc 2.3.6 combo with success.

Hello
I'm also working with ML403 board from Xilinx and have the same problem
as you. The boot process stops after decompressing with the message "Now
booting the kernel". We also used gcc-4.1.0 for the cross compilation.
So, I would be glad to know, which gcc version have you used to get a
working kernel!
Thanks,
Andreas

First step:
Get a JTAG debugger and look at the __log_buf address.

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.
Thanks,
Andreas

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.

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.
Thanks a lot,
Andreas
