RE: [microblaze-uclinux] USB support with uClinux

[Paul Hartke <phartke@xxxxxxxxxxxx>]

Just want to clarify--do you want to download FPGA configuration (*.bit) and
 processor executable (*.elf) files to the board via the USB interface?
That works just fine on the XUPV2P board and is the only supported USB
mechanism.

Or do you want to connect USB peripherals--ie, keyboard, mouse, storage
sticks, webcams, etc--to the board and have Microblaze uClinux communicate
with them?  To my knowledge, that is not yet implemented and the stock
XUPV2P board USB interface will not use it even when Microblaze uClinux USB
support is in place.
