Unable to update the Firmware 2.1 to 2.2
  • I am the owner of the third motherboard (V4), the first one the usb connector was unwelded, the second one red color motherboard was non operational, the last one is OK. This black one colour card ( V4 ??) seems ok, but I am unable to update the firmware from 2.1 to 2.2.
    Why ?
    I try with Gimbal GUI I am each time the same error message Invalide avrdurde exit code
    I try with the two other software with the same unsucess !!

    Did you have solution ??
