This is due to many factors but in general semihosting debug needs to be rewritten to work the same way as any LL_DEBUG, e.g. with a header in arch/arm/include/debug/semihosting.S This is a long term solution and needs testing on real hardware and/or software models using semihosting. For now disable uncompress debugging under semihosting.
