Firmware update problems

Problem
Cannot update firmware
After firmware update, Duet no longer visible

Solution
Check the instructions, and follow them carefully
If the ‘bossac’ command fails, make a note of the error, and contact support
If the error is to do with the port not being found, try sending the update command without this part: ‘–port=COMxx -U true’
If the board is inaccessible following a firmware update, but then does reappear after the ‘erase’ and ‘reset’ buttons are pressed.
When you send the bossac command, leave the ‘-R’ off the end. Once the flash has completed, wait for 10 seconds, then press ‘reset’ button on the board,
and see if the board shows up correctly
