How is the IRQ_TEST_SCENARIO_4 supposed to work?
I suspect that there might be a lurking race condition somewhere in
that test.
Some, not all, of the (M33/M23) targets gets stuck in that test when
the ConfigRegression.cmake config is built with IAR in Debug mode.
If I build it with RelWithDebInfo then the test runs OK for all
applicable targets. No problems with Debug builds for the other
configurations.
Occasionally the test will run successfully also for a normally
problematic target if I run it in the debugger and stop execution at
breakpoints, but it is very random, which is why I suspect there
might be a race problem.
