Sorry about filing this as an "issue" ... I have no idea how else to do this.

I bought a HX1K based board and ... I'll omit the backstory.
Anyway, I'm using HEAD from both your repository and walac's pyusb repository, and on a freshly-inserted device I see the following:

$ ./regtool.py
Traceback (most recent call last):
File "./regtool.py", line 31, in
main()
File "./regtool.py", line 20, in main
for atype, arg in args.actions:

with board.get_gpio() as gpio:

Subsequent execution of either iCEburn or regtool return the final longest backtrace.

Help?

Great work on this project, but I am having terrible trouble getting this installed. All i can do is create an egg file, but there's nothing i can do to make it run. I've tried installing it and running from in python3. I've tried to run it with python3 -m, i've tried installing it, and it just disappears. If i try and run the egg directly it says it can't find main even though i can see it in the source code.

Is there any way the documentation can clarify how to get a iCEburn.py file out of the installation? This is driving me nuts, i've been googling for hours trying to figure this out. I'm a C / C++ developer, so python for me is the antichrist, i just don't understand it at all.

Hi,

First, thanks for this utility, really useful :)

Now, I'm having an issue with it is that after using it, I need to unplug and replug the board or I get a "timeout" error from PyUSB the second time I try.

ATM I've resolved it by doing a .reset() on the board.dev before quitting but that seems a bit brute-force.

I'm using Python 3.4 and git master of pyusb.

Cheers,

Sylvain

Retracted! Working well, I have a LP1K board in fact not a HX1K

~~Runs without error, board wont run (tried various examples including icestorm example for this board).
