Hi Wolfgang,
I am totally newbie in u-boot who is trying to learn how to write/execute standlone application and as to start with learning I just blankly followed the steps I found on U-Boot twiki and on google. I personally don't know what those address mean. But would be very kind of you if you could please kindly help me understand what's the right way to learn which address to use and or how can I find this out?
You are correct I am using EDB9302 motherboard which is based on ARM920T processsor. Please kindly help me.
Regards, Vipul.

You must not just follow the steps without thinking.
Method 1:
EDB9302> tftp 40000 /tftpboot/hello_world.srec
What makes you think this is the correct download address?
Using ep93xx_eth-0 device
ep93xx? Sounds line an ARM system to me. Are you sure you have RAM at this address, and that this is the correct address for this standalone app?
EDB9302> loadb 0x100000 ## Ready for binary (kermit) download to 0x00100000 at 115200 bps...
What makes you think this is the correct download address?
Please help me, how can I test simple hello world program like this on U-Boot.
Well, if you continue trying random addresses you will probably continue getting random results.
Please read the FAQ: http://www.denx.de/wiki/view/DULG/MyStandaloneProgramDoesNotWork
Then think about your sytem, nd check the load and entry point addresses.
