MacSamba

MacSamba (Copyright © 2006 - 2009 Nick Howes) is a command line utility program for downloading code into an Atmel ARM CPU via Atmel's SAM-BA and a USB port under Mac OS X. It is released under the GPL. You may use it for free (but donations are gratefully accepted - click on the button below).

I've tested with an Atmel AT91SAM7XC256-EK, and several custom boards using AT91SAM7XC256 and AT91SAM7XC512. It should work with other devices with a few tweaks. MacSamba is slow compared with Atmel SAM-BA (I think because it writes one word at a time). Note that the binary is built for Mac OS X 10.6 Snow Leopard - for use on older versions, you will need to rebuild it.

There may be bugs in the code that cause malfunctions.
Use this software at your own risk.

Known bugs and issues

Doesn't always recover properly from errors - it you get timeouts or it hangs, reset the target.

You will need to unload the AppleUSBCDC.kext before using MacSamba (which will disable other serial ports):
sudo kextunload /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBCDC.kext
To reload the kext:
sudo kextload /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBCDC.kext
