No, we didn't do it before, because we were handling it in arm_cpu_do_interrupt(), which is A/R-profile only. The M-profile code goes via arm_v7m_cpu_do_interrupt() which doesn't check for semihosting when it sees an EXCP_SWI. > Just gate it with && !arm_dc_feature(s, ARM_FEATURE_M) then? Yes, I think that's the right fix. thanks -- PMM
