Hi all!
I spent around an hour fast forwarding through the fun of getting this running on OSX (honestly, not a masochist - 2014 MacPro is a great laptop for simultaneous embedded, client and server work).
Pondering if anyone else has got Arduino working under OSX? Errors pasted at bottom - I’m switching to the bare toolchain now to establish a baseline and then work backwards. At some point I’ll switch to a VM I guess and try arduino on linux but that would be cheating at this early stage!
OpenOCD uses libusb to access the FTDI proprietary functions but an Apple pre-installed driver is in the way - unload it:
sudo kextunload -b com.apple.driver.AppleUSBFTDI
[removes /dev/tty.usb*]
…Note that you have to re-load the built in drivers to see the serial port again. I’m currently using a pyftdi app to access the serial (miniterm.py) so its not a huge issue yet (happy to write up instructions later). To restore:
sudo kextload -b com.apple.driver.AppleUSBFTDI
Recommend installing lsusb so you can see what’s going on:
brew tap jlhonora/lsusb && brew install lsusb

Run through the arduino board support instructions - compile works but download is screwed up:

Then error 2 until I reboot (assuming JTAG is in bad state and initial scan out returns crap that causes it to bomb out until its reset):
