[ECOS] about redboot, gdb and embedded ice

["A Roturier" <roturier at hotmail dot com>]

hi list,

i make reboot image from arm aeb2 code and try to load it onto samsung
snds board(both with same samsung arm7 chips. its merely for testing purpose
only and i don't expect ecos' gonna run at all :-)). i have a few questions:

1, how do i change byte ordering from little endian to big endian?

2, after downloading redboot image onto the target with arm-elf-gdb, i can
   only start single step execution by issuing 'nexti' in gdb console. 
either
   clicking on those execution 'buttons' in the main window or issuing 
'next'
   commman in console will make gdb 'hang'. this seems doesn't make sense.

3, after downloading image and before execution, what are the [correct] 
initial
   valuse of cpu registers? i observe that register values don't change a 
bit
   after i connect to target and before the execution starts(cpsr=0x60000010 
in
   this case. i.e., cpu is in user mode. and pc is not the specified ecos 
entry
   point). is this the right condition?

thanx for your attention.

kc
