Hi Ian, I am writing you directly because the issue is associated with IAR ARM tools, so the might have some concerns regarding the release of information. I was trying recently Sourcery G++ Lite 2010q1-188 for ARM EABI (GNU assembler verson 2.19.51). In general it was comiling some basic files, but wen tried to link the produced obj file with IAR linker got an error that the entry point of the program can't be found. I did contacted IAR and they responded that EWARM tools are use ARM ABI ELF/Dwarf standard version 2.06B. Wondered on what version of ELF/DWART standard current gcc version supports as well as if you can recommend a way for converting elf files in different version formats? Thank you! Mitko
