Is it as simple as changing the A8 > references in .config to M3? The Cortex-M3 is a Thumb2-only processor. I'm not so sure how binutils, gcc and the C libraries handle this case. Search the archives, there has been a thread on the subject some time ago. If all goes well, you should set the following: CT_ARCH_ARCH: armv7-m (I'm not so sure about that one, if it fails, leave the field empty) CT_ARCH_CPU : cortex-m3 CT_ARCH_TUNE: cortex-m3 Do it within the 'menuconfig', it's easier than editing the .config file. > Actually, I am a little surprised that this isn't a standard > configuration considering the number of popular processor based on > this processor. As I have no way to test such a toolchain, I don't provide a sample for it. If you manage to make it work, then I would be glad you submit your .config for inclusion. Regards, Yann E.
