It may be a good idea to set BR2_GCC_TARGET_ABI to aapcs-linux even if BR2_iwmmxt is selected. > Could you give it a try with those 2 lines changed? What exactly do you want me to try? I guess I would have to remove my .config and go thru menuconfig, select ARM iwmmxt and then check what gets sets for BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH and BR2_GCC_TARGET_ABI? Is that correct?
