Topic: Windows update breaks download? (Read 450 times) previous topic - next topic


I'm working in my schools lab. I installed 0009 and AVRstudio (to get the mkII driver installed). Burned a chip and burned a sketch on a board. BBB with a FTDI cable.

As I was leaving the lab I noticed a windows update was taking place after I tried to shut down the computer. The machine has XP on it.

This morning I get the dreaded AVR errors

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

The cable shows up as COM 4 so it's seeing that but no dice on connecting.

I read though some of the rest of the discussion on people with similar erros and will try and turn verbose on. I downloaded new FTDI drivers but there seems to be no installer with them. When I use hardware manager and try updating the drivers, it doesn't seem to show any of the files in the driver folder.

Is there a specific meaning for those particular AVR errors?

Thanks in advance for any light you can shed on this, I'll keep banging on it.

Oh one more thing - board works perfectly in Diecimila mode on a Mac.


I got bit with a known bug - this is elsewhere on the forum, but if you're using an FTDI cable you need to do the following:

Device Manager - Com Ports - USB Serial Port - Port Settings - Advanced button - Set RTS On Close

This is research from David Fowler at uchobby.com
