[etherlab-users] Etherlab Master on a Raspberry PI

[Ben Yehuda, Raz]

I used the raspberry as well. Please note that the BCM chip uses usb 2 lan as it does not have any real ethernet interface.

Hi Raz

After the comple of the kernel source (which took 13 hours) finished
building, I rebuild the etherlab master and now it the modules load. IE
ec_master and ec_generic.

I've just tested our ClockWork system on a EK1814 which worked correctly
using about 3% cpu load.

Cheers
Mike
