My PyTrack 2.0, in combination with the gpy, is having issues with booting up after I updated the firmware version to version 16 (
It keeps throwing the following error that the checksum is failing for the device. Also, I tried to find an older firmware version or perform an update via the
PyCom update firmware toolbut this tool also keeps failing.
I tried to do the whole upgrade process on multiple PC's (Linux and Windows), but no success so far.
