Firmware Update Verification Failure - synthetos/TinyG GitHub Wiki

The cause of the Firmware Update Verification Failure is that the processors LOCKBITS were set. These need to be reset to NOLOCK status.

Things You Will Need

1. AVRstudio 6.1 or later.
2. AVRISP mkII Programmer (NOT A CLONE OR A KNOCKOFF)
3. Windows Machine

Procedure

1. Launch AVRStudio
2. Go to the Tools menu then the Device Programming
3. Now for the Tool select AVRISP mkII from the drop down menu.
4. Then select ATxmega192A3 from the Device drop down menu.
5. Click Apply
6. Now select the Lock bits from the vertical list on the left.
7. Set ALL Values to NOLOCK. (See image below to see how this should look with the correct LOCKBITS set.)
8. Click Program

Conclusion

With your LOCKBITS correctly set you should be able to make it through the whole firmware update process.
