How to flash

Enter bootloader

The DFU state in the bootloader can be accessed in 3 ways:

Bootmagic reset: Hold down the key at (0,0) in the matrix (usually the top left key, grave accent in the default keymap) and plug in the keyboard;
Physical reset button: press the button on the front of the PCB, next to caps lock, for at least five seconds;
Keycode in layout: Press the key mapped to QK_BOOT; in the default layout, that is top left key ('grave') in layer 1.

How to compile and flash

You can compile the Iron 165R2 default keymap by using the following:

make magnum_ergo_1:default

And use dfu-util in the command line or through a GUI like QMK toolbox to upload the firmware to the PCB. To directly flash the PCB after it is put into a DFU state, use:

make magnum_ergo_1:default:flash
