I haven’t quite got the CWlite working after an idle hour fiddling with it. I’m fully aware I’ve got one ahead of the docs and I’m being difficult and using Linux over Windows, so I’m figuring I’m just finding things ahead of time that you’re going to fix anyway.
My system: Kubuntu 15.04 amd64
I installed ubuntu packages for numpy and scipy and pip install’d the rest, and was able to run the UI. I got permission errors trying to access the chipwhisperer as user, so I created a UDEV rule:
# cat 52-cwlite.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2b3e", ATTRS{idProduct}=="ace2", MODE="0666"
This allowed me to run the CWCapture program, although I don’t get any example scripts in the menu - I don’t know if this is due to the hardcoded paths which are referred to in one of the python files. I can select the SimpleSerial taret and ChipWhisperer-Lite as a scope, but after correctly finding the board, and printing its serial number, it then issues a traceback due to self.usbdev not being initialised in the CWUSB_USART.
Configuring manually in the UI:

Additionally the Project Text Editor always has an error that it can’t open “untitled.cwp” - not sure if that’s relevant.
I’ve now built from a completely blank python virtualenv with pip, and it’s worked. I’ve been able to record traces. I can’t select the Example Script but if I run it from the cmdline it works and starts the UI.
Saving the project appears to work but then “project file changed by GUI, SYNC LOST” is shown, and saving causes this error:

A trace file doesn’t appear to get generated, due to that last errror, the cwp file is only 200 bytes, with the contents:

python scripts/cwlite-simpleserialxmega.pyThis worked once, and then started crashing. Unplugging the CW-lite board and plugging it back in fixed this. I don’t know if that was the problem over my distro packages?
Also I tried the git repo but I assume the openocd submodule is not public as I can’t fetch it.
