FPGA/host/run.sh shows:

java -cp wpa2.jar Wpa2

... but this currently fails with:

Error: Could not find or load main class Wpa2

This looks closer:

sudo java -cp wpa2.jar WPA2

... but this also fails (at least on my setup), with:

Firmware upload time: 101 ms 4 FPGA's found FPGA 0: FPGA configuration time: 79 ms Warning (try 1): error sending control message: Connection timed out Error: bus=001 device=027: selectFPGA: error sending control message: Connection timed out

dmesg shows:

[Edit - note that this is a known-working board - works with JtR jumbo]

You're right about the main class being uppercase. For the other stuff, you'd likely have to recompile and force firmware upload:

make
sudo java -cp wpa2.jar WPA2 -f

The result won't be particularly useful right now - I'm still writing a proper protocol for the host communication, my available time has been pretty limited lately. Hopefully done in the next week or two!

Fair enough! FWIW, these may be useful as reference. They work well in my testing.
