I recently updated one of my photon devices to 1.2.1 and noticed that an interrupt that reacted based on change of a button click gives an SOS now. I was wondering if there was any change between 1.1.1 and 1.2.1 that might’ve caused this to start happening? I tried looking at the chagelog but other than some mentions of ISR, I’m not too sure I’ll find anything there. They’re a bit too technical for me unfortunately and I dont understand the majority of what they mean.
Might be related to this i think https://github.com/particle-iot/device-os/pull/1761
The SOS code is a heap error (14 blinks).
