I'm thinking of having it emulate a serial port. This is for Linux As Bootloader, the next-generation iPAQ bootloader, and some new iPAQs do not have a serial port, so we need USB support.

What's the serial port used for ... command interpreter? Or downloading files?


One question--why not use CDCEther and g_ether?  They are already
written and give you all the features of TCP/IP--better than just
a serial port.

Networking is not compiled into LAB. Too big.

But network boot protocols (UDP, DHCP, TFTP) were designed to fit into much smaller ROMs than you're working with ... :)

BLOB has a mini-stack; and I've certainly seen it done with
standard kernel networking code.

And of course, PXA has enough endpoints that it's possible
to eventuall support BOTH models at the same time!
