### This Keymap uses the nanoBoot bootloader to maximize available firmware space.
|
||
|
|
|
||
|
|
As is, the firmware will be too large if using the standard bootloader. Removing `DEBOUNCE_TYPE = sym_eager_pk` from the `rules.mk` should get the size under the limit.
|
||
|
|
|
||
|
|
If nanoBoot is not going to be used, delete or comment out the following from your `rules.mk`:
|
||
|
|
```make
|
||
|
|
BOOTLOADER = hid
|
||
|
|
BOOTLOADER_SIZE = 512
|
||
|
|
PROGRAM_CMD = $(HID_BOOTLOADER_CLI) -mmcu=$(MCU) -w -v $(BUILD_DIR)/$(TARGET).hex
|
||
|
|
```
|
||
|
|
|
||
|
|
nanoBoot can be found here: [nanoBoot](https://github.com/sigprof/nanoBoot) I used the string-descriptors branch as it was the latest update.

To ISP Flash nanoBoot: `avrdude -p atmega32u4 -c avrisp -U flash:w:/Users/DempseyTech/nanoBoot/nanoBoot.hex:i -P /dev/cu.usbmodem123451 -U lfuse:w:0x7F:m -U hfuse:w:0xD6:m -U efuse:w:0xC7:m`
|

|
|
||
|
|
You will need to change the path in the CLI command to match your file structure.
|
||
|
|
|
||
|
|
QMK Toolbox will not recognize controllers using nanoBoot, instead use the CLI to flash.

To Flash: `qmk flash -kb splitkb/kyria/rev1 -km john-ezra -bl hid_bootloader`
