Guru Meditation Error Dumps



  • I am getting frequent crashes with any code that uses interrupts or threads and thought that I would create a thread recording the crashes that I (and others) encounter so that they can be investigated and hopefully fixed.

  • @jmarcelino - good point, thanks I have added them.



  • You should add which board (WiPy, LoPy or SiPy) the dumps come from and precisely which firmware version you're running, otherwise they can't be used for tracing the problem
