Redboot SDRAM Virtual Memory Mapping


Greetings,

I am using Intel' Xscale PXA270 processor and my SDRAM
(32-bit,104 MHz) 64MB is interfaced to BANK0 having
the physical address 0xA0000000.

In the hal_mmu_init function, the SDRAM is mapped to
virtual address 0x000 using the X_ARM_MMU_SECTION
macro as CACHED. It works fine.

But if I change the virtual address to 0x800 or any
other address other than the 0x000 the redboot does
not boots and halts at early stage after the LED 7
instruction.

Is it that the SDRAM cannot be mapped to any other
address except 0x00000000 in Redboot?

I require the SDRAM to be mapped to 0x80000000, since
I want to boot wince image.

Regards,
Tejas Pawaskar
