Gt power a6 - custom firmware
Hi, just flashed my gt power a6 with custom firmware from https://github.com/stawel/cheali-charger
I used my usbasp and avrdude to update the software. The programming header on the charger was a perfect match to the header on the usbasp. Firmware used:cheali-charger-imaxB6-clone_1.00-20150711_atmega32.hex The reason for using the cheali charger firmware is that cell 6 voltage was way off, and the stock firmware can only be calibrated once. So far, the software looks very good :-) Backing up original firmware Writing new firmware to the atmega32 chip Last edited by jogeiremil; 11-01-2015 at 01:47 PM.. Reason: Insert images etc. |

Hi, good question - I dont remember exactly how I chose the firmware, but I do remember checking images here: https://github.com/stawel/cheali-cha...ee/master/docs
Try to compare your charger to the images above. Clone / copy / counterfeit / cheap chargers have a lot of variance in hardware, even though the outside is similar. Quote:
