In this video I show you how to flash the new firmware from KK onto the KK2 board using a typical USB/ASP programmer and the flashtool from LazyZero (Christian).
In the video, I started with the USB/ASP programming cable's 6 pin connector poiinting one way but had to turn it around the other way because the KK2 board was not receiving power from the programmer.
The battery error displayed during the menu review is caused by not having the LIPO connected to the sensor headers underneath the board.
Please remember to write down your current PI values before flashing as the process erases all of yoiur settings and sets them back to their new defaults. Do not change the defaults back to what they were before you flashed because the new firmware offers better performance and your previous values may change with this new firmware.
