My question is, has anyone tried to load USRP FPGA image without a PC? For
example using a micro-controller (Like Microchip PIC 18F4550 which has USB
2.0 port) with SD memory holding the image?
This might work. The control end point works in both USB 2.0 and USB
1.1 mode. As long as you were only using that, you could probably get
the FX2 image and the FPGA image loaded.
It's worth a try.
Atmel has a similar part (AT90USB1287) and has a devkit, AT90USBKEY,
that might save you some work. It's a USB OTG 2.0 device, $30, has the
right dongle, and has a pair of 64Mbit flash chips on board. The power
supply is spec'd to 8-15V, but might be coaxed to run off something
lower. Digikey/Mouser/Arrow stocks 'em.
