Let's Split Flashing

(More information at qmk_firmware/layouts/community/ortho_3x10/wanleg/readme.md)

Make the QMK DFU .hex

make lets_split/rev2:wanleg:production dfu=qmk

Burning EEPROM settings and Firmware

Navigate to the directory with your .hex file and the eeprom-lefthand.eep and eeprom-righthand.eep files in it.
Burn Left Side With QMK DFU and Firmware
avrdude -b 19200 -c avrisp -p m32u4 -v -e -U lock:w:0x3F:m -U efuse:w:0xC3:m -U hfuse:w:0xD9:m -U lfuse:w:0x5E:m -U eeprom:w:eeprom-lefthand.eep -P comPORT -U flash:w:YOUR_production.hex:a

Burn Right Side With QMK DFU and Firmware
avrdude -b 19200 -c avrisp -p m32u4 -v -e -U lock:w:0x3F:m -U efuse:w:0xC3:m -U hfuse:w:0xD9:m -U lfuse:w:0x5E:m -U eeprom:w:eeprom-righthand.eep -P comPORT -U flash:w:YOUR_production.hex:a

Change comPORT to whatever port is used by the Arduino (e.g. com11 in Windows or /dev/ttyACM0 in Linux). Use Device Manager in Windows to find the port being used. Use ls /dev/tty* in Linux. Change YOUR_production.hex to whatever you've created in the previous step.

Using QMK DFU

Once QMK DFU is burned to your ProMicro, you can then flash subsequent hex files with make lets_split/rev2:<keymap>:dfu dfu=qmk
The dfu=qmk conditional will set BOOTLOADER = qmk-dfu instead of BOOTLOADER = caterina
