Pycom Firmware Update Tool failed to upload FW

  • Hi!
    After I played around with some custom FW builds, I wanted to upload the original 1.7.5.b1 FW, but the update failed!
    I erased the flash with the, but the update tool won't work.

    Any ideas anyone?


  • Solved it.
    I used the pycom upgrader 1.1.1.b2 to downgrade to FW 1.6.0.b1. Afterwards, the upgrade to 1.7.5.b2 worked seemlessly.
