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.

:-) thanks for asking

machine: embedded artists lpc2478 oem - arm7
compiler: arm-none-eabi-gcc-4.3.3.exe
U-Boot: u-boot-1.1.6 with embedded artists patches

bin file is generated with "arm-none-eabi-objcopy -O binary app.bin"

uClinux boots correctly

Thanks!

Ouch.  An out-of-tree port, and a prehistoric one at that.

U-Boot 1.1.6 is more than 5 years old.  In terms of software
development that was when saber-toothed tigers lurked behind each
other stack frame.  You do not want to use such old code.  Do yourself
(and us) a favour and update.

Also, GCC 4.3.x is probably not a clever choice on ARM.  If I remeber
correctly, it has tons of problems.s lurked behind each other stack
frame.  You do not want to use such old code.  Do yourself (and us) a
favour and update.

Also, GCC 4.3.x is probably not a clever choice on ARM.  If I remeber
correctly, it has tons of problems.

But your biggest problem is the out of tree code - we don't know it,
so how should we be able to help?

Best regards,

Wolfgang Denk

Thanks for the feedback!

Is upgrading gcc to 4.5.1 reasonable?

I'll see what I can do about the u-boot-1.1.6

It might be helpfull if you can point me at documentation/examples that
explain how a standalone application should be developed (I've read the
documentation, but didn't find examples that compile out of the U-Boot
source tree).

Thanks!
Bart

solved, was a linker issue

gcc 4.3.3 and U-Boot 1.1.6 are ok for now, will upgrade once I understand
how to port U-Boot to a "new" board

thanks for all the feedback, appreciated!

with much regards,
Bart
