Arduino IDE wiFire Rev D not responding

[Gareth O'Brien]

I've been using chipkitCore with a Rev C without problem.

I went to test the same code on my "spare" board which turns out to be a Rev D.

I've uninstalled chipkitCore upgraded to digilentCore - which got me a little further. But now when I attempt to flash Blink to the board, it fails as follows and locks up the COM port requiring a PC reboot.

Any ideas?

Thanks,

Gareth.

More info ...

Without restart I switched to the Rev C board and disconnected the Rev D. The ran the same upload from Arduino IDE (of Blink sketch) without problem:

Hello @Gareth O'Brien,

Unfortunately, it looks like the Rev D version of the board that you have is missing the bootloader. Do you know if the board has been used with MPLAB X or something similar in the past that may have erased the bootloader?

Thanks,
JColvin

Hi JColvin,

It seems the problem is no the lack of the bootloader.

I have got to the point where I can upload code once. The code executes without problem.  If I then attempt to upload again, so for example during debugging this is iterative, then I get:

    The upload process has finished.

Note: I briefly see red leds at the usb connector as though it is receiving but then nothing.

If I unplug from USB, everything resets and I can upload again ... once!

My workaround is to get everything working on a RevC board (which works fine) and then flash the result to the RevD. Which of course only works because I have both.

Gareth.

Hi @Gareth O'Brien,

What version of Arduino and Digilent core are you using?  Are you selecting the wifire rev d for the board?

thank you,

Jon

[Gareth O'Brien]

Hey Jon,

I'm using Arduino 1.8.5 (just upgraded from 1.8.2) and Digilent core 1.0.4

I'm now getting the same behavior with the Rev C.

I'm going to move the whole setup to a different computer to rule out something funky with the USB subsystem on the laptop.
