I kept the link address back at 0xc0000000. Doing mkimage , I did load address and entry address as 0x0.
On my FADS823 board, I do a download to 0x100000. And gave a bootm 0x100000.
But the system hangs after Uncompressing Kernel Image... Note: I have compared the bd_info stricture of linux and u-boot . It is the same . Also the IMMR address. I do mkimage on gzipped binary image of vmlinux.
Please advice. Rupesh

The RAM memroy map as seen with the "bdinfo" command in u-boot says.. 0x00000000 to 0x00800000.
These are physical addresses.
I'm trying to boot linux kernel ( linux-2.4.4-2002-10-06 from DENX) on my board. By default , the kernel is build at 0xC0000000. (This memory is not mapped by u-boot).
This is a virtual address.
Do I have to change the kernel linking to a address that is within, 0x00000000 and 0x00800000 ?
No. You MUST NOT change the Linux kernel, or it will break. Physical and virtual addresses are completely different beasts.
