I am using u-boot1.1.3 with Linux-2.6.13 for Accelent IDP DEVKIT with PXA255 \
processor (uses Xscale). The size of SDRAM is 32MB and flash is 16 MB.

I have used TEXTADDR=c0008000 and ZRELADDR=a0008000

The problem while porting under debug mode,
1. The kernel is getting compressed 
2. Displaying debug messages, but hanging after that.
3. If i use TEXTADDR=a0008000 and ZRELADDR=a0008000, it is entering in to \
start_kernel() function and makes LED to blink, but it is not executing printk() \
function. I got the following output under debug mode.

The problem while porting without debug
1. The kernel is not getting compressed.

I got the following output
