Chuck: your point is well taken. Code that used to be ROM on I/O boards is now either in a Flash memory or perhaps in onboard RAM loaded by some operating system at boot time. Some would call that a proprietary binary blob. It is certainly much easier to update this code than to distribute a new ROM chip. Technology is constantly changing. I think the line is a blurry one. One could easily argue that the BIOS is a binary blob present in all PCs. My point wasn't to start this potential flame war. I was specifically asking about the Beaglebone Black. I'm actually curious just how Free it is. My research has not turned up any proprietary binary blobs for the this board. I figured that somebody in WLUG probably owned one and would know the answer. maddog's suggestion was also a good one. Thanks!
