News: Bootloader added to Semitone Diamond |
|
Thursday, 01 July 2010 10:29 |
|
The latest SVN revision of the Semitone Diamond OS now includes an AVR109/910 compatible UART bootloader written by Martin Thomas (et al.), customized to support the Diamond I/O shift registers.
Bootloader mode is entered when the Standby front panel button is held while the Diamond is reset. Updates can then be flashed via UART with any AVR programmer utility that supports the AVR109 protocol, such as avrdude. You can use any frontend UART interface, such as Bluetooth (wireless updating is fun!), USB, RS232, RS485 and so on.
However, you are not forced to use the bootloader for programming the main OS image. When flashing via ISP, both OS and bootloader ROM images are merged. So you can still use your favorite ISP programmer and use the bootloader any time later.

The Fuse Calculator got a huge update. It now supports 141 AVR devices. The data is based on the description files of AVRStudio 4.18. Still, please beware of inconsistent or broken original data from Atmel. Please notify me if you find errors so that I can patch the database.
