Truly speaking I don't know exactly how the U-boot booting process happens, I mean i don't know how it is loaded in differrent stages and where.... Can you plz suggest some tutorial for the same....I couldn't find one.
See README, Wiki and sources...
I had changed TEXT_BASE since I assumed that after power-on the system reads from location 0x00000000. So I had changed the TEXT_BASE address so that the system would read from location 0x00000000 where I have placed my u-boot.
That's wrong. U-Boot copies itself into RAM and then executes from there. So either use external or internal (as I do) RAM address. See also u-boot.lds (linker script) and cpu/arm925t/start.S what happens here.
