strange behaviour Pixymon / vmware / win7

Pixy Software
#1

Hi,
i’m using Pixy with Pan/tilt base.
I’m running Linux (Centos 6.5) as the vmware host and win7 as a vmware guest.

The pan/tilt demo works ok, but when i started Pixymon (version 1.0.2) on windows,
the console display:
Pixy detected.
error: Unable to connect to device.Pixy detected.
between “Pixy Detected” and the “error:…” there is a 5 seconds pause.

BUT, if i turn on pixy in “firmware upload mode” (holding down the button while powering pixy up)
then Pixymon display “Pixy programming state detected”, the firmware is written into the flash,
and the program starts to work as aspected (display raw or cooked output, set signature, run pan/tilt demo, save config parameters,…)

Does Pixymon performs a different init() when in DFU/programming mode?

Looks like a vmware related issue.
In fact i build Pixymon on the main OS - linux centos 6.5, no Win-on-vmware involved
Pixymon connects correctly with pixy and works as aspected…but when i try to apply/save in “configure parameters”, the program crash (Illegal instruction (core dumped)).

TIA

Hi Luca,

So the program still crashes on save when you’re not running any VMs? Is the connection issue only present when the VM is running?

Hi Scott,
yes, the program crashes on save even when i run it directly on centos 6.5 - Kernel 2.6.32-431.23.3.el6.x86_64 - It’s the installed OS, no VMs involved.
The attached file “pixy_linux.txt” contains a detailed report (log files, terminal window output) of the problem.

The connection issue appears only when Pixymon is running in a VM.
If i’ll be able to have Pixymon “Save Parameters” working on centos (no VMs) that would solve my issue.

In case you need them, i’ve attached 2 more reports for the different VMs configurations tested.

PS:
I’ve notice in the images of the wiki (“Installing PixyMon on Linux”) that the doc was
made on a Virtualbox VM.
I’m using VMPlayer but, if the Pixy team is using Virtualbox and they have no problems with
it, i may try running Ubuntu 14.04 in a Virtualbox VM (i need Ubuntu 14.04 for ROS)

TIA

Thanks Luca! I’ll pass this info along to one of the devs.
