Executing ELF file with U-Boot

[SAeeD]

Thanks, I got the usage of -d option.
I have three more questions:
1. In one of your replies, you mentioned about the baud rate of Mini2440
console that is 38400 bps. I wonder have you built and used RTEMS on
Mini2440? (On the board or on QEMU)

2. Why did you TFTP hello.img to address 0x32000000? Because I used my load
address (0x30000000) as the address of TFTP and after execution of *bootm*,
I got lots of
s3c_mc_write: Bad register 0x17983c
s3c_mc_write: Bad register 0x179840
errors with no "Hello World".
Is 0x32000000 a special address?

3. I applied mkimage to make an image of hello.exe (ELF version) with
following command:
*mkimage -A arm -O rtems -T kernel -C none -a 0x30000100 -e 0x30000100 -n
hello-img -d hello.exe hello.img*
But when I use
*tftp 0x32000000 hello.img
bootm*
again i get lots of
3c_mc_write: Bad register 0x1df548
s3c_mc_write: Bad register 0x1df54c
errors. I have no idea what is the reason of that.

Thanks in advance
