I noticed Greg doing exactly that ...  I'll hope to see it in pre2! :)

And FWIW I think the hotplug scripts have known about "ehci-hcd"
for a while now.  So system startup should bring that up with
little trouble.


> Dave - any progress on a build environment and/or test apps?

I'm not sure quite what you mean by "build environment".
Are you saying it doesn't "just build" in the kernel, now?

Test apps ... one option is to use a USB 2.0 storage device.

The "fxload" utility (on linux-hotplug) works nicely to download
FX2 firmware, including test firmware.  I just checked in some
updates for second stage loader support ... needs more testing
though.  (And note that "fxload" is now linux-hotplug/fxload, not
linux-hotplug/admin/fxload, in CVS!)

Turns out the Rev E FX2 silicon (current, the first "production"
silicon) works a lot better than the Rev B stuff we first got from
Cypress.  It enumerates reliably at full speed too, for starters!

As for test apps, I've tweaked the "bulk src" example a bit
so that it's a straight source/sink, and it's been invaluable
for testing bulk and interrupt transfers.  I've got a driver I use
with it via "dd bs=... count=... < ... > ..." to read and write
whatever data I want.  And when time allows, a new version
will be supporting ISO ... :)

For SDCC support, I've got a "fx2.h" that's got a good part
of the necessary microcontroller-specific stuff in place.  It
needs updating for the production (rev E) silicon, but if
anyone wants to develop firmware for this without using
the Keil tools, that'd be a good place to start.
