Hi Peter! Thank you for your help, it works fine with "-M integratprcp -cpu cortex-m4" but I might choose another board as you suggested. I didn't have in mind that we switched to M4 instruction set.
Where do I get the information that integratorcp is not good for cortex-M3? Or better question: where do I get information which machine is good for it? Actually "-M help" doesn't give me any with M3 (already tried "none" and "virt" without success). On the other hand I see all cortex variants in the output of "-M integratorcp -cpu help" so I had a good feeling about it... -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1636126 Title: qemu-system-arm segfaults on "smulbb r7, r5, r5" Status in QEMU: New Bug description: I'll attach a binary that runs fine with qemu-system-arm V2.2.0 but V2.7.0 segfaults.
