Thanks for all the valuable info.
Actually i went thru the doc/README.standalone file and theres a table which tell abt load and entry point address of various architecture.
For arm load = 0x0c100000 entry pt = 0x0c100000.
I still have 2 doubts( hope it doesnt annoys u) 1.Cant i tftp my hello_world.bin to any valid address of RAM eg "tftp 0x30000000 hello_world.bin"
2.How do i find out the entry point of my binary image?
Regards, Jhavk

I have read README.standalone. My target board
is
smdk2440(Arm 9).
So i transfer hello_world using tftp to address 0x0c100000 and then call "go 0x0c100000 hello
world"
What makes you think that 0x0c100000 is the entry point of the standalone application?
But after that the application seems to get
stuck
and nothing happens. Eventually i have to reset the board.
This is because you tried to run code where none is. Pay attention to the entry point address.
I have some doubts:
- Which file should i send. I think it should
be
This depends on which tool or protocol you use for the download.
hello_world and not the srec or bin format. I
ran
This is wrong. hello_world is an ELF file, so it may only be used by tools / protocols that understand ELF files. The SREC file has to be used by tools / protocols that understand Motorola S-Record files. The BIN file has to be used by tools / protocols that understand raw binary images.
command on all 3 and found that hello_world is
the
one meant for ARM.
Wrong again. All images (hello_world, hello_world.srec, hello_world.bin etc) are all teh same images, just in different format, depnding on which protocols or tools you want to use.
2.Is the load and start address correct? May be
its
different for ARM9?
The load address ooks ok to me. The entry point is probably somewhere else.
