I am having issues connecting either of my new 3pi’s using either of my Pololu USB AVR programmers.
Running: Win7 x64
I’m able to connect to the USB AVR Progs (one comes up with COM1, COM2… the other COM7/COM8)
AVR Studio 4 comes up and recognizes that something is connected, pops up the window saying “STK500 in ISP mode with ATmega328P”, and immediately pops up a message with “ISP Mode Error …”
Down the bottom, I get
"Setting mode and device parameters… OK!"
“Entering Programming Mode… FAILED!”
“Leaving Programming Mode… OK!”
I’ve checked that the programming mode is ISP, and set ISP Frequency super low at 4.000 kHz (attainable returns 3.998kHz)
This occurs for both USB AVR programmers and both 3pi bots, one of which I’ve upgraded to firmware v1.05. I’ve not reused any cables (cables are kept with their respective USB AVR Programmers.) I’ve also tried a fresh install of the Pololu AVR Development Bundle on a fresh install of Win7.
