Event Manager not working on QEMU_x86 or native_posix

[mglettig]

The sample in nrf/samples/event_manager crashes when running on QEMU_x86 with the following output:

I'm using NRF SDK v1.6. Do I need to configure something in KConfig in order to get support for QEMU?

When building and running for native_posix I get a segmentation fault.

Update:

I noticed that the simulation / emulation works on the board qemu_cortex_m3. That leads me to the question is there any QEMU board available that reflects the architecture of the NRF9160 (Cortex-M33)?

Kind regards,

Michael

Hi,

I believe you can do some basic network stuff with qemu_x86, but for non-networking stuff, you would need a nRF9160-DK.

The mqtt_simple sample have some configs and overlays for qemu_x86 :https://github.com/nrfconnect/sdk-nrf/tree/v1.6.1/samples/nrf9160/mqtt_simple

But I see that for e.g. the event_manager tests, native_posix and qemu_x86 is excluded: https://github.com/nrfconnect/sdk-nrf/blob/v1.6.1/tests/subsys/event_manager/testcase.yaml

That leads me to the question is there any QEMU board available that reflects the architecture of the NRF9160 (Cortex-M33)?

No, not that I'm aware of.
