Today I received this message, while working with my Bela with a CTAG Cape. I was working in SuperCollider, but the same message appears when running C++ examples.
I did nothing out of the ordinary prior to the message appearing.
I see that this post concerns a similar problem: [https://forum.bela.io/d/1314-bela-mini-pru-interrupt-timeout]
