New Model F77 - cannot toggle NKRO after flashing the firmware from the QMK Configurator

Hi guys, not sure if I'm missing something obvious. Everything else about this keyboard works flawlessly, but LShift + RShift + N for toggling NKRO no longer works after flashing my remapped QMK hex file (which is compiled from the Model F Beta QMK Configurator). I followed the instructions from this video: https://www.youtube.com/watch?v=Esj2gZ0XptE

If I re-flash the original .hex from the provided zip in the video, then the LShift+RShift+N NKRO toggle works again. It seems like the Beta QMK configurator doesn't build the file with NKRO.

Finally, I also tried to manually add another "Togg NKRO" button from the configurator, but it still doesn't seem to do anything.

Did anyone have similar issues, or have any idea how I can work around this to enable NKRO? Appreciate any help!

Hmm, I think I understand the problem. Downloading the full source from the QMK Configurator and examining qmk_firmware\keyboards\xwhatsit\brand_new_model_f\f77\rules.mk, I see that NKRO_ENABLE is not set to yes:

Code: Select all

NKRO_ENABLE = no            # USB Nkey Rollover
So it looks like I'll have to update that build option and compile this locally instead of relying on the QMK Configurator.

As a note, for the firmware files I have compiled on the project web site, I enable the option to toggle NKRO through a key combination but set it to disabled by default for compatibility reasons, as detailed in the manual. For the QMK configurator web site I believe that NKRO cannot be toggled back on.
