Issues

iceprog is not supported in docker and should be installed locally using ./icestorm.sh which kind of defeats the purpose.

OS X

To unload the default and vendor drivers in case iceprog refuses to connect:

sudo kextunload -v -b com.apple.driver.AppleUSBFTDI
sudo kextunload -v -b com.FTDI.driver.FTDIUSBSerialDriver

Reload with

sudo kextload -v -b com.apple.driver.AppleUSBFTDI
sudo kextload -v -b com.FTDI.driver.FTDIUSBSerialDriver
