Hi I have a Pololu v2.1 firware 1.0.2
And I can burn bootloader just fine, after burning bootloader I can upload program just fine.
So what is the problem?
Well, after doing the above with success, I want to upload a program again, so I press upload in Arduino IDE and it starts uploading, but fails with:
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
I tried disconnecting the programmer and connecting it again. I tried resetting the target. I tried a LOT. Nothing helps.
The only way to program it again is by uploading a new bootloader. And then upload new software. But that is waay to inconvenient.
Thanks in advance.
BTW, yes. Connections has been checked. I have checked that I select the right ports. Actually I can press upload (with success) then press upload again and it fails.
