Flashing 1.7.8.b1 (containing frozen code) LoPy 4M from MSYS is not working



  • Hello,

    Form MSYS, everything looks fine: build and flash 1.7.8.b1 (containing frozen code) on 4M LoPY .

    Unfortunately after reboot we are getting Lopy RGB led as red color and is not working.
    Using the firmware upgrade with 1.7.8.b1 is working. Also everything is working fine if we are doing the same operation from MSYS with previous LOPY.

    Do we need to configure special memory addresses for flashing on 4M LoPy?

    Here is the output from msys:

  • @Colateral Before föashing your own image, you have to erase flash completely. So with the Pycom IDF, issue:

    make erase
    make flash
    

    You have to reset the device again between the two commands. I noted that already as an issue, but is is not fixed yet.
