[U-Boot] Beginner

[bart.deboeck at xenopz.com]

Dear All,

  I'm completely new to U-Boot and trying to develop a standalone
application (developing on a Windows machine with the Code Red IDE).

  So far, I managed to start a simple application that toggles GPIOs.
However, when I try to call a function in main() the app immediately
crashes or hangs.

  U-Boot reports errors like:

fast interrupt request
pc : [<a1f97bfc>]   lr : [<00017e58>]
sp : a1fffcf0  ip : a1fadf04 fp : 7ff7f1d2
r10: acd7a91e  r9 : 353a342d r8 : a1f5cf70
r7 : ffffd1d4  r6 : ffffd307 r5 : ffffd197  r4 : ffffd163
r3 : 20000013  r2 : ffffd14f r1 : fa47fca1  r0 : ffffd01b
Flags: nzCv  IRQs on  FIQs on  Mode SVC_32
Resetting CPU ...

  In what direction should I start looking to solve this?

  Your feedback is appreciated!

Thanks!
Bart
