The key take-away here is that the image is loaded every time a session
starts with the E3xx FGPA, so you have to mention the desired
FPGA image as a device argument for your apps, otherwise, it'll use
Some USRP devices (N2xx, USRP2, X3xx) have a "one time FPGA load"
doctrine--you use a "loader", and the FPGA image remains until
you explicitly change it. In other devices (USRP1, B2xx, E3xx) the
FPGA image is loaded dynamically as part of your application
session with the device.
