hi , I am working on a multi tasking application to debug which I am using ARM AXD debugger .The compiler used is GCC with version 3.2. The application runs on an ARM9 board with ecos as the OS. The problem I am facing is when i try to interleave disassembly while doing the stepping, the debugger says "failed to interleave file".The image is an .axf(arm executable format) file. I looked what could be the problem with my debugger setting, did not get any clue as yet.Kindly let me know what could be the problem. I want to interleave disassembly and step through assembly code. Does the axf file created by gcc and ARM compiler differ?Does'nt the gcc for ARM support interleaving of C source?Any help would be great. regds , Jitha
