WiPy + PyTrack Windows USB Setup Problems

[shaun_nicholson]

Hi

My WiPy + PyTrack arrived yesterday but I have been struggling to get these to connect via Windows 8 Pro + USB.

I have read numerous Forum posts, doc pages etc and tried just about everything I can with no luck to setup drivers, firmware etc.

I am trying to connect to the board using Putty via Serial but it just won't connect. The only way I can connect is to connect my Windows machine to the WiPy WiFi AP and then use Putty / FileZilla to connect to 192.168.4.1.

I think I have updated the PyTrack Firmware to 0.0.4. However, using the PyCom Firmware updater doesnt seem to work (struggling to connect the two pins when mounted on the PyTrack). The PyCom Firmware Updater doesn't seem to be able to connect via USB. I am not sure if this is related to my failure to get USB setup or not.

Is there a command I can run when connected to check the firmware version of the PyTrack and the WiPy to compare with latest?

Is there a list of valid Firmware combinations anywhere? The firmware download section on the PyCom site seems to just download the firmware updater.

Is there a definitive list of setup instructions for installing the correct Windows 8 drivers (I read somewhere this should just work but it didn't seem to).

Any help would be appreciated. This board seems awesome and I can't wait to get playing with it (other than via the WiPy AP).

Thanks

Shaun

@jcaron Thanks for the tip. Output below.

from pytrack import Pytrack
py = Pytrack()
py.read_fw_version()
4

Which I think means it had flashed successfully (partly as my previously loaded libs had disappeared!).

I had tried to connect the External I/O header as an alternative but had similar lack of luck. Tried High speed transfer both ticked and unticked based on reading another similar post.

Just tried this again with same result. Flash tool states it is connecting... then shows a Failure! warning. The only COM port in the drop down is COM3 but I am not sure that's the attached PyTrack as removing the PyTrack from USB doesn't de-list the item listed in Device Manager.

I am still concerned that it is more related to not having the correct Windows drivers in place that's preventing things from working as they should.

Thanks again for the response.

Regards

Shaun

@shaun_nicholson To enter the firmware upgrade mode on the WiPy while mounted on the Pytrack, it may be easier to connect pins 1 and 5 on the External I/O header of the Pytrack (they're connected to P23 and GND, they're just easier to manipulate).

You can check the Pytrack firmware version using the Pytrack library (https://github.com/pycom/pycom-libraries/tree/master/pytrack) and code similar to:

from pytrack import Pytrack
py = Pytrack()
py.read_fw_version()
