Fault during interrupt handling in unmodified demo code #1

Closed ryanfeist2 closed 8 months ago

ryanfeist2 commented 8 months ago

Compiling unmodified code and running it on RAK4631 produces the following error over the RTT interface. Patch has been applied prior to building. Please help me understand what is happening.

Just cloned following readme instruction worked like a charm for sample dut, 

west init -m https://github.com/RAKWireless/RAK4630-Amazon-Sidewalk-Example rak-sid-workspace
cd rak-sid-workspace/
west update
cd rak-sid/
west patch
west build -p -b rak4631_nrf52840 app/rak4631_sid_dut/

notice sidewalk is not on same version vs yours

not sure what's going on on your side

Hi @hallard, thanks for your feedback. It turns out that I wasn't running a completely unmodified rak4631-rak1901-demo code and had some faulty lines of code inserted that were halting the thread at runtime. It works now. Thanks for your support!
