Except for that, you can disable the bootloader by disabling the HWBE fuse bit or even remove the bootloader code completely while programming via SPI. The meaning of arguments should be self-explanatory. Search or use up and down arrow keys to select an item. This project consists of one header file and one source file and it includes wrapper functions which allow to access the flash and fuse-bit programming functions in the stock bootloader on some of the Atmel’s USB-enabled AVR chips. You can download the files from my github repository. The avr-gcc compiler has the necessary headers to write your own bootloader code, which would allow me to achieve exactly what I needed, but since the chip I was using ATmega32u4 already had a stock bootloader, I wanted to use it instead.

You can download the files from my github repository. Unfortunately, I couldn’t find any libraries to use the rfu it provided, so I decided to write my own. If you have succesfully run the code on any of those devices or made modifications which allowed it to run, please let me know in the comments. The meaning of arguments should fdu self-explanatory.

It also provides a convenient function which writes a whole page to the flash memory. This project consists of one header file and one source file and it includes wrapper functions which allow to access the flash and fuse-bit programming functions in the stock bootloader on some of the Atmel’s Wtmel AVR chips.

Hi Alex, normally the atmega32u4 will run the bootloader only when reset while the HWB is low. Except for that, you can disable the bootloader by disabling the HWBE fuse bit or even remove the bootloader code completely while programming via SPI.

While developing my mechanical keyboard project, the GH60, I came across the need dfuu program the flash memory during runtime.

No search term specified. Why I wrote it While developing my mechanical keyboard project, the GH60, I came across the need to program the flash memory during runtime.

Using The library provides static inlines for all the bootloader’s functions: Check out dfj original articlewhere I describe how it works. So you can connect HWB to ground through a switch and then you can run the bootloader if amel press this button, hold it and then reset probably by pressing another button.

The first one performs a jump to the bootloader section and gets the chip into DFU mode and the second one writes a whole flash page at address addr with provided data.
