Did you try reading the FAQ?  For example this one:

Actually, maybe the wiki might use some improvement. Some of the users might 
find it hard to find this FAQ. Mohamed, do you have any ideas on improving the 
wiki? :)

[U-Boot] execution of standalone hello_world not happening

Dear Wolfgang Denk,

Thank you very much, your wiki helped me a lot.

what went wrong:
when i did as described in the link i got the below output. please not i did not change anything in the code of hello_world.?
but the mistake i did was i loaded to some location which was not the loadaddr of my board's standalone application.
?
${CROSS_COMPILE}nm -n hello_world

00080000 N _stack
0c100000 t $a
0c100000 T hello_world ----> this is my load address present in arch/arm/config.mk?CONFIG_STANDALONE_LOAD_ADDR = 0xc100000
0c10009c t $d
0c1000bc t $a

and when i gave the bellow command it worked like slicing peace of cake.
?
(MSM 7x30) # loadb 0xc100000
## Ready for binary (kermit) download to 0x0C100000 at 115200 bps...
## Total Size ? ? ?= 0x00000252 = 594 Bytes
## Start Addr ? ? ?= 0x0C100000
(MSM 7x30) # go 0c100000
## Starting application at 0x0C100000 ...
Example expects ABI version 6
Actual U-Boot ABI version 6
Hello World
argc = 1
argv[0] = "0c100000"
argv[1] = "<NULL>"
Hit any key to exit ...

Thanks,
Mohamed Haneef M.A
