Dear wolfagang,

Again thank you very much.


Please note :



I used  the following command : 

mkimage -A arm -O u-boot -T standalone -C none -a c1000000 -e c1000000 -n 
"Hello World" -d hello_world.bin Hello.img

I  transfred the image file to (using loadb 0x43e00000), the md command
shows the following:

Bootm  0x43e00000 raises an undefined instruction exception. 


 Booting kernel from Legacy Image@43e00000 ...

On the other hand, the command arm-linux-gnueabi-nm hello_world | grep
hello_world

0c100000 T hello_world

so, the entry point of the image 0c100000

Hence, I also used the command:

mkimage -A arm -O u-boot -T standalone -C none -a c1000000 -e 0c100000 -n 
"Hello World" -d hello_world.bin Hello.img

the command bootm 0x43e00000 returns the following :


AUB ARNDALE 5250 # bootm 0x43E00000
## Booting kernel from Legacy Image at 43e00000 ...
   Image Name:   Hello World
   Image Type:   ARM U-Boot Standalone Program (uncompressed)
   Data Size:    594 Bytes = 594 Bytes
   Load Address: c1000000
   Entry Point:  0c100000
   Verifying Checksum ... OK
   Loading Standalone Program ... OK
OK


and the program hangs on at this stage giving no sign of life.


Please help what I am missing.

Many thanks and best regards,
