Title: Bus Blaster + openOCD on OSX Mavericks
Post by: alvarop on January 05, 2014, 05:35:20 pm
Not sure if anyone else is using this configuration, but everything stopped working for me after updating to Mavericks.
Apple now includes an FTDI driver with the OS, which takes control of the FTDI device before openOCD, so you get the following error:
Error: unable to open ftdi device: unable to claim usb device. Make sure the default FTDI driver is not in use

To fix this problem, unload the Apple kext:
Code: [Select]
sudo kextunload -bundle com.apple.driver.AppleUSBFTDI

This works, but now you can't use any other FTDI devices. There is a solution though!

Open the Info.plist and comment out the AppleUSBEFTDI-6010-0 key/dictionary and save it.

Reload the kext
Code: [Select]
sudo kextload -bundle com.apple.driver.AppleUSBFTDI

This should now let openOCD use the Bus Blaster (while letting you use other FTDI devices)

If you want more info on how I came up with this solution, I put some more details on my blog (which I can't link to because I'm new, but should be easy enough to find)
