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
Uhum ... so my wild guess is you have a PXA based machine ? What compiler do you use? What version of U-Boot ? please, be more specific.
