I recently purchased a Pololu USB avr programmer v2.1 and am having some issues with getting it working. Using the SPI interface on two Arduino Mega clones I can bootload and then upload a sketch. However on two Nano clone boards I can only bootload them and uploading a sketch produces a error that they are not in sink and tries 10 times. Also how do I use the second header on the programmer the one with tx and rx pins.
Thanks for any help.
Hi Rowan,
The second header on the Pololu USB AVR Programmer v2.1 is the USB to serial (We have a tutorial on how to use USB to Serial ).
Are you using the correct bootloader and configuration for the Nano board? Are you able to give the specific error and any codes it provides?
I believe I have followed the above tutorial. However uploading code using the USB to Serial does not work, I can upload code directly onto the same Mega not using the programmer however with the programmer I have had no success. I am trying to press the reset button at the correct time however I am not sure how important the timing is.
The error is as follows:

An error occurred while uploading the sketch
Hi Rowan,
The timing of the Reset button is critical to getting the upload to work. I would play around with the timing and see if you can get it to work that way. Based on your error codes everything else seems to be working as expected.
Here is the full user guide for using this programmer. You may need to set it up with a utility prior to using it.
