Core 0 panic'ed -- Fix by reducing CPU speed



  • Had "Core 0 panic'ed......" errors on various M5StickC units.

    Reduced CPU speed from 240MHZ to 80MHz, problem seems to be gone .......

    Units run cooler too (at 240MHz units were slightly warm to touch).

    In this situation, we haven't met. our all firmware is used 240MHz default. maybe you could check it does related to your program.



  • @m5stack :

    So far the "80Mhz" fix is holding up since Oct-21st , running on 2 units.

    Program and IDE are the same when running at 240MHz.
    When the problem occurs (at 240MHz), both units lock up so bad, that they will not even reboot.

    I will try a few more M5StickC running at 240Mhz (with exact same program and programmed from same IDE) and see if they again lock up after a few days.
