Ok, thanks.

There is no aeMB so there is no firmware in the sense that we have on the
USRP2.  The OMAP fulfills that role because it has direct low-latency bus
access to the FPGA.  The FPGA can directly interrupt the CPU as well.

Interesting - those interrupts are through the GPMC bus? I assume then
the kernel module collects the interrupts, and passes the data to
userland (i.e. UHD).


One more question - about cabling this time. Does the UE100-KIT come
with any adapters to assist with plugging my standard sized USB
devices (keyboard/mouse, flash drive, etc.) into the various USB ports
on the front panel? If not, can you describe which port is which type
- the serial console port looks like a mini-B, and the USB OTG and
Host ports look like they might be micro-B's, but I'm not familiar
enough with the mini/micro USB ports to tell just from the picture on
your data sheet.

For the USB host function I use a cable I bought from Digikey, WM17494, which is a mini-B to mini-A cable. For the console connection the cable is a standard A to mini-B.
