We released a new Brick Viewer version. With the new version it is possible to not only flash Bricklets, but also Bricks. This is now done automatically from our server, there is no need to download a suitable firmware by hand.
This means that SAM-BA as a third-party tool is not required anymore. It seemed that the Atmel tool made lots of trouble and there was no Mac OS X version. Furthermore we reimplemented some stuff to reduce dependencies. The Brick Viewer now doesn’t depend on pylab, scipy and matplotlib anymore, this should make the installation on embedded devices and small Linux distributions quite a bit easier.
