Multiple/Exchangeable bootloaders

Post by matrixstorm » Tue Jun 11, 2013 3:25 pm

Hi community.

As a demonstration of one of the new features in revised USBaspLoader (https://github.com/baerwolf/USBaspLoader)
I added an example for its demonstration board (http://matrixstorm.com/avr/tinyusbboard/).
There you can change the default bootloader (USBaspLoader) into a properly patched BootloadHID. (The patch basically ensures you also can switch back to USBaspLoader.)

Of course you also could switch back again. In principle this works with every bootloader implementing the "spminterface.h" properly.

I hope to get some feedback.
Useful comments always are appreciated.

Best regards,
matrixstorm
