> Yep, Chrysalis store the keymap in eeprom and kaléidoscope compile it in the binary file, so you have to either : tell your sketch to mot use the eeprom layouts (you can search here or in the github issues) reset the eeprom (there is a make command to do it, or use the «reset to factory» option from the Chrysalis firmware upgrade menu - don’t forget to export your layers as a backup, just in case…) Happy hacking slight_smile
