## USBasploader
|
||||
|
||||
USBasploader is a bootloader developed by matrixstorm. It is used in some non-USB AVR chips such as the ATmega328P, which run V-USB.
|
||||
|
||||
To ensure compatibility with the USBasploader bootloader, make sure this block is present in your `rules.mk`:
|
||||
|
||||
# Bootloader
|
||||
# This definition is optional, and if your keyboard supports multiple bootloaders of
|
||||
# different sizes, comment this out, and the correct address will be loaded
|
||||
# automatically (+60). See bootloader.mk for all options.
|
||||
BOOTLOADER = USBasp
|
||||
|
||||
Compatible flashers:
|
||||
|
||||
* [QMK Toolbox](https://github.com/qmk/qmk_toolbox/releases) (recommended GUI)
|
||||
* [avrdude](http://www.nongnu.org/avrdude/) with the `usbasp` programmer
|
||||
* [AVRDUDESS](https://github.com/zkemble/AVRDUDESS)
|
||||
|
||||
Flashing sequence:
|
||||
|
||||
1. Press the `RESET` keycode, or keep the boot pin shorted to GND while quickly shorting RST to GND
|
||||
2. Wait for the OS to detect the device
|
||||
3. Flash a .hex file
|
||||
4. Reset the device into application mode (may be done automatically)
|
||||
|
||||
## STM32
|
||||
|
||||
All STM32 chips come preloaded with a factory bootloader that cannot be modified nor deleted. Some STM32 chips have bootloaders that do not come with USB programming (e.g. STM32F103) but the process is still the same.
