Thanks for the additional information concerning the operation of the Shield board in relation to the operation of the bootloader at the time of program upload. A very interesting issue to say the least.
I would like to see a video, not because I don't belive you but because I want to see how it reacts compared to mine. Please video from the beginning each step you do from power off to uploaded code showing your LED behaviour so we can compare. We are not the only ones having this problem, we are just the only ones working on it.
Are you intimating that Sparkfun may have changed the bootloader on Ardupilots with the Atmega 328?
Somebody with this problem that lives in South California? Would be nice have access to a problematic hardware.
R1 measured at 1K
I have been helping Fred troubleshoot his board on the other thread concering uploading problems with the GPS plugged into the Shield board.
If it helps at all, I have three of the Shield boards purchased at different times and on all three boards R1 is 1K.
I have not attempted to program my Ardupilot 328 board yet, but with the GPS plugged into the Shield board and power applied to the Ardupilot board, I get 4.3v on the base of Q1 and the GPS led does not come on. Also, I have both the Sparkfun FTDI (3.3v) board and the Adafruit FTDI cable to try programming the Ardupilot board once the GPS problem is resolved.
