Hi Yoann: Unfortunately I keep getting the same error. When I set CAN_USE_THUMB_INSTRUCTIONS symbol I can build the code but I cannot run on mini2440 for some reason - says file not found meaning that it cannot recognise the executable format.
Btw my linux flavour is Angstrom, and I build with GCC version 4.2.4. I start to think that that might be related to the toolchain that I am using although I can compile and run other apps without any problem. Any other suggestions? thanks.
