That error > is fixed using mode "arm" instead of "thumb": If I am not mistaken, swi allows context mode switch between arm and thumb modes, if you compile your tool to be mode thumb, I guess it makes not much sense to link against c library, as you loose arm context. Try to build a bare metal (arm-elf|arm-eabi) tool which defaults to thumb, appropriate for cortex chips with M profiles. > $ export CLFS_ARM_MODE="arm" > > Using "arm", the target 'all-target-libgcc' ends ok, but I would like to get > the cross-toolchain with that "thumb" feature enabled. > > Hope you can give me some advice based on your own experience. I guess arm tool is able to spit thumb code without that switch. I might be well mistaken, so if someone knows about it, please correct me.
