Title: Lost my QMK config file - can I pull it from the board itself?
Post by: Ludovician on Tue, 20 October 2020, 19:39:56

Years ago I set up a layout that has always worked well for me, except today I accidentally hit whatever keybind I set to swap ctrl+caps and I don't know how to swap it back - the original file used to program the board is lost. Can the QMK software export the config to a file at all?

Thanks.

Edit: Forgot to mention, if relevant, the board is a DZ60 PCB (atmega32u4?)

Edit2: I've resolved the short term issue with an EEPROM reset. If possible I'd still like a way to retrieve the config.

I don't see why you wouldn't be able to pull the file from the board itself - I would think it would work both ways so one can mod a current flash on a board (only thing I have to relate this to is flashing a car's ECM/ECU)

if i remember correctly in QMK the map is compiled into the firmware, if it is the case then the answer is yes you can but will be quite complicated, as you would need to dump the firmware off your chip and either use an hex editor or a decompiler to find your table back. although if there is someone who knows something about TMK and so QMK it would be hasu (creator of TMK)
