[Adeos-main] I.MXL won't boot after patching with adeos-ipipe-2.6.27-arm-1.12-00.patch

[gwenhael.goavec]

Hello,

I wish to test adeos and Xenomai on Arm9 I.MXL(MC9328) based
platform. I have already tested with linux-2.6.26.5 and
linux-2.6.24.3. Ipipe worked fine and the system has booted
correctly.
But with linux-2.6.27.13 and others 2.6.27.XX System
won't boot. The last message I have is : 

BIOS> boot

done, booting the kernel.

kernel_start() is never called.
	
However, when CONFIG_IPIPE is not active, the system works
well!

Do someone have the same problem ?
What is the solution for having  linux-2.6.27 working
with this processor ?
Thank you very much.

What exactly is the support selected in the Linux kernel for this
processor? Could you try the printascii in printk trick to see exactly
where the boot fails?

I have selected IMX for the processor type.

I have applied the printk trick but I have no new informations on the
terminal. The problem seems to being between decompress_kernel() and
start_kernel().

Then you have a problem in the memory layout. Check all the addresses
and see if no two zones overlap.
