@nordic-krch Are you looking at this, seems to break on most ARM architectures...

[nashif]

To reproduce this in Qemu, export QEMU_BIN_PATH to point to host qemu (assuming you have a very recent version on the host) and run it on mps2_an385

[nordic-krch]

@nashif I will be able to look at it tomorrow.

[nashif]

@nordic-krch any updates?
