/** \brief Bootloader Size in *bytes*
|
||||
* |
||||
* AVR Boot section size are defined by setting BOOTSZ fuse in fact. Consult with your MCU datasheet. |
||||
* Note that 'Word'(2 bytes) size and address are used in datasheet while TMK uses 'Byte'. |
||||
* |
||||
* Size of Bootloaders in bytes: |
||||
* Atmel DFU loader(ATmega32U4) 4096 |
||||
* Atmel DFU loader(AT90USB128) 8192 |
||||
* LUFA bootloader(ATmega32U4) 4096 |
||||
* Arduino Caterina(ATmega32U4) 4096 |
||||
* USBaspLoader(ATmega***) 2048 |
||||
* Teensy halfKay(ATmega32U4) 512 |
||||
* Teensy++ halfKay(AT90USB128) 1024 |
||||
* |
||||
* AVR Boot section is located at the end of Flash memory like the followings. |
