Another possible way to go would be to modify the firmware so that it looks for a firmware update file on the SD card. During initialisation, if it finds a firmware update file on the SD card that is a different version to the one installed, it updates its firmware from the file on the SD card. So long as all new Duets sold contain firmware with such a feature, uses will be able to update their firmware simply by copying the firmware update file onto the SD card and power-cycling the Duet.

Hi Dave
Yes, we've considered this. The main problem is that you effectively need two firmwares. The initial one (or extended bootloader) that runs at startup, that can access the SD card (or network) and compare the installed firmware to the firmware on the SD card (or online), and which can overwrite the flash memory (without overwriting itself), tell you what it's doing (by the serial console) then exit memory cleanly before loading the actual firmware! The Duet doesn't have a lot of memory (100k), but at least should have enough flash memory to hold, effectively, two firmwares.
It's all do-able, probably, we just haven't had the skills and time available to implement this (or something like it).

I can confirm that Bossa the gui version does NOT work with Mac computers, it never locates the port.

Hi Guys,
I am using a 32 bit Mac with OSX 10.6.8 and have Arduino 1.0.6 installed.
I have drilled down the folder structure but can see no sign of bossac. In the /hardware/tools directory there is only another folder called avr.
I have read further up about using Board Manager to add bossac, but can not see this in any of the menus on my set-up.
Any advice much appreciated.
Ralph
