It is possible running the demo program caused the E310 to find another
E310 on the network and become confused. (I know this sounds crazy,
there is an open bug for this)

I'm working on tracking the argument string to stop uhd fro doing this.

In the meantime, hopefully this course of action works:

Download the latest factory image from:


Use bmaptool to write the image to an 8BG (the stock card on older units
is 4G) with bmaptool.


I have heard a positive report of bmaptool working on OSC, just make
sure you write to the device that is the entire card.

The fpga images on the SD card do match the installed version of UHD, so
you should not run the image downloader program.

My problem is, I'm on my MacBook today which does not have that software installed, and I've been unable to get that set up easily on this computer in the past. So what I'd like to do is find a solution that doesn't involve me installing a bunch of stuff on this host computer.
