Cortex-M MCU Emulation with Renode | Interrupt

Blog

I’m trying out the example and everything works fine when running the sim manually: I see “hello world” and the “button pressed” prompt.

However, when I try to run renode-test tests/test-button.robot it gets stuck at:

Preparing suites
Started Renode instance on port 49152; pid 8998
Starting suites
Running tests/test-button.robot
+++++ Starting test 'test-button.Should Handle Button Press'

When I kill it I get the following output:

Second signal will force exit.

Does someone know what I might be missing?
