# Bootmagic
|
|
|
|
There are three separate but related features that allow you to change the behavior of your keyboard without reflashing. While each of them have similar functionality, it is accessed in different ways depending on how your keyboard is configured.
|
|
|
|
**Bootmagic** is a system for configuring your keyboard while it initializes. To trigger a Bootmagic command, hold down the Bootmagic key and one or more command keys.
|
|
|
|
**Bootmagic Keycodes** are prefixed with `MAGIC_`, and allow you to access the Bootmagic functionality *after* your keyboard has initialized. To use the keycodes, assign them to your keymap as you would any other keycode.
|
|
|
|
**Command**, formerly known as **Magic**, is another feature that allows you to control different aspects of your keyboard. While it shares some functionality with Bootmagic, it also allows you to do things that Bootmagic does not, such as printing version information to the console. For more information, see [Command](feature_command.md).
|
|
|
|
On some keyboards Bootmagic is disabled by default. If this is the case, it must be explicitly enabled in your `rules.mk` with:
|
|
|
|
```make
|
|
BOOTMAGIC_ENABLE = full
|
|
```
|
|
|
|
?> You may see `yes` being used in place of `full`, and this is okay. However, `yes` is deprecated, and ideally `full` (or `lite`) should be used instead.
|
|
|
|
Additionally, you can use [Bootmagic Lite](#bootmagic-lite) (a scaled down, very basic version of Bootmagic) by adding the following to your `rules.mk` file:
|
|
|
|
```make
|
|
BOOTMAGIC_ENABLE = lite
|
|
```
|
|
|
|
## Hotkeys
|
|
|
|
Hold down the Bootmagic key (Space by default) and the desired hotkey while plugging in your keyboard. For example, holding Space+`B` should cause it to enter the bootloader.

# Bootmagic Lite
|
|
|
|
In addition to the full blown Bootmagic feature, is the Bootmagic Lite feature that only handles jumping into the bootloader. This is great for boards that don't have a physical reset button but you need a way to jump into the bootloader, and don't want to deal with the headache that Bootmagic can cause.
|
|
|
|
To enable this version of Bootmagic, you need to enable it in your `rules.mk` with:
|
|
|
|
```make
|
|
BOOTMAGIC_ENABLE = lite
|
|
```
|
|
|
|
Additionally, you may want to specify which key to use. This is especially useful for keyboards that have unusual matrices. To do so, you need to specify the row and column of the key that you want to use. Add these entries to your `config.h` file:
|
|
|
|
```c
|
|
#define BOOTMAGIC_LITE_ROW 0
|
|
#define BOOTMAGIC_LITE_COLUMN 1
|
|
```
|
|
|
|
By default, these are set to 0 and 0, which is usually the "ESC" key on a majority of keyboards.
|
|
|
|
And to trigger the bootloader, you hold this key down when plugging the keyboard in. Just the single key.
|
|
|
|
!> Using bootmagic lite will **always reset** the EEPROM, so you will lose any settings that have been saved.
|
|
|
|
## Advanced Bootmagic Lite
|
|
|
|
The `bootmagic_lite` function is defined weakly, so that you can replace this in your code, if you need. A great example of this is the Zeal60 boards that have some additional handling needed.
|
|
|
|
To replace the function, all you need to do is add something like this to your code:
|
|
|
|
```c
|
|
void bootmagic_lite(void) {
|
|
matrix_scan();
|
|
wait_ms(DEBOUNCE * 2);
|
|
matrix_scan();
|
|
|
|
if (matrix_get_row(BOOTMAGIC_LITE_ROW) & (1 << BOOTMAGIC_LITE_COLUMN)) {
|
|
// Jump to bootloader.
|
|
bootloader_jump();
|
|
}
|
|
}
|
|
```
|
|
|
|
You can additional feature here. For instance, resetting the eeprom or requiring additional keys to be pressed to trigger bootmagic. Keep in mind that `bootmagic_lite` is called before a majority of features are initialized in the firmware.
