Enable Drivers Hangs or Requires Internet Connection about icestudio

[Jesus89]

Drivers > Enable option in mac installs libftdi using homebrew and also performs some kextuload: http://apiodoc.readthedocs.io/en/stable/source/installation.html#manually. This behavior is equivalent in the cli "apio": https://github.com/FPGAwars/apio.

Can you install it (pip install -U apio), execute this command (apio drivers --enable), and paste the output?

Thanks.

I appear to have had some undone steps. First I had to install pip (even though I already had a functioning python installation) using the get-pip.py script. Then I installed apio using pip. Then I could run the above command. The output follows:

System:~ home$ apio drivers --enable

After having done the above, Icestudio can enable and disable the drivers without any difficulty. Problem fixed!

I guess the ultimate solution is to either include making sure pip and apio are installed as part of the installation instructions, and/or having the enable/disable functions in Icestudio check for this and provide an error message for that condition. Thanks much for the help!

Hi,

Icestudio installs a virtualenv with apio in local $HOME/.icestucio/venv. No internet required because all packages are located inside the package.

I have check the Icestudio commands, and recently a new configuration for drivers enable including:

/usr/local/bin/brew update
/usr/local/bin/brew install libftdi
/usr/local/bin/brew link --overwrite libftdi

Probably the internet connection message comes from brew update, and the app "hang" was the libftdi download. I will investigate that.
