Hi I have two arduino pro minis that I have been using for a copter setup - they have been working - uploading etc fine.
I've been playing with software updates etc and now I can upload to one fine (ie the usb ftdi cable and port etc are still working fine) but on the other board I think I've done something to stop it uploading.
This is what happens
I connect the ftdi plug I get the red LED permanently on I get one flash of the green LED then about a 3 second pause of no green LED, then the green LED flashes continuously. If I hold the resest button the green LED stops for as long as the button is held down then starts flashing immediately it's released again.
If I try to upload to the board I get
avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I've tried hitting reset at various times during the upload process but can't clear it ant get it to upload?
Have I ruined the board somehow - no physical damage etc and like I say - the other board is uploading fine still so the pc connection is ok?
(Windows - Vista - 32 bit using USB FTDI cable).
I'm running Arduino 0023 specifically as this is what the software I am using for the copters needs.
so - one works - the other flashes green LED continuously - I can't find anywhere to tel lme what this means?
Any suggestions chaps?
