(fixed) problem USB programming the P2 Evaluation Boards

refaQtor

It was me... I bought the last two P2 Evaluation Boards,

thinking it would be nice to have a tidy package to tote with me and try random coding bits on the go (with onboard USB-serial). Alas, I'm getting no love from them on either Windows or Linux. On Windows, I can see the blinkety-blink of USB scanning/connecting, and the board will show up in the Device Manager where I would expect. But, though PNut will scan (I see the LEDs flicker on the Evaluation Board) it will not recognize it as a P2.

Nothing stands out to me on the website (extra specific drivers) or in the documentation of additional steps I need to take to make this work. What am I overlooking? Any clues?

can't speak for Windoze but Linux should be as simple as:

$ ls /dev/serial/by-id/ -l
total 0
lrwxrwxrwx 1 root root 13 Dec 26 16:08 usb-Parallax_Inc._Propeller_P2-EVAL-ES_DN43WU6I-if00-port0 -> ../../ttyUSB0

Thanks. @evanh , I see exactly that on Linux (ubuntu) with your command, and SpinTools does indicate that there is a "/dev/ttyUSB0" port available, I can select it from the port menu, but attempting to use it gives alert that "port not opened" and SpinTools Discover Devices is unable to find it either.

I did just confirm that good old prop-plug behaves with PNut on Windows.

and you've added yourself to dialout group I presume?

$ sudo usermod -a -G dialout <username>

ah! recent re-install, and hadn't done that dance again yet. thanks.

oddly, now, though I didn't change anything on Windows, the P2 Eval Board is now responding, after I'd checked that it worked with SpinTools and FlexProp on Linux.

Thanks!
