Linux without Mmu

Hello,

I am trying to run Linux-2.6.38 without MMU.
I successfully complied it, but while booting it stops after uncompressing
Kernel,

(with MMU enabled, it works fine)


Do you have any idea what is wrong?

Thanks.

Is there a special reason why you want to run this CPU without its MMU?
Just an idea: At least the address the kernel must be linked to must be
within the SDRAM address range. With MMU the kernel is linked to 0xc0000000

We are just experimenting something.

SD RAM base address = 0x50000000, right?

1.
I tried by changing configuration in arch/arm/Kconfig-nommu
DRAM_BASE=0x50000000
DRAM_SIZE=0x10000000
2. 
I looked at arch/arm/mach-s3c64xx/Makefile.boot
   zreladdr-y := 0x50008000
params_phys-y := 0x50000100
It is already in physical address.

But the result is still same.
Are there anything else I should consider?

The memory is connected to chip select #6 and this one corresponds to CPU's
address 0x30000000.
