This is the source code of the boot loader used in the Attiny microcontroller that is part of the U:Kit sensor kit project. It is a slight modification of the TinySafeBoot aka TSB boot loader by Julien Thomas. And as such it is licensed under the same terms as the original TSB boot loader.
The source code is based on the work done by Masami Yamakawa that contains modifications for better compatibility with Attiny1634.
You will find also small modifications for the need of U:Kit.
In order to compile and flash the source code and do some modifications to it you will need
- AVR Assembler. Our recommendation is to use the assembler compiler coming with AVR Studio 6 or later
- AVR binutils. In Ubuntu 16.04 you can install them with the following command
sudo apt install binutils-avr. - AVR Dude. In Ubuntu 16.04 you can install it with the following command
sudo apt install avrdude.
- AVR programmer. A cheap USBasp or similar will be perfectly enough. Make sure that you have the latest firmware flashed on the programmer.
