Thanks for the link. I hadn't seen it yet.

I'm not sure they realise over there that this isn't going to plug in and mine right now. A lot of the code is present but it's not debugged and it will require quite a bit of work still to get it working as expected, not to mention there is no driver yet for cgminer. So the best case initially is using the ktest program to feed test data and getting any result nonces back.

I've been working today on a kslog utility which takes sharelog data from cgminer and decodes the merkle and midstate data so that suitable test data that is known to give a nonce result can be fed in with ktest. Also, this data is used for the chip detection algorithm so it's needed for completing the firmware. kslog is written and works but I have no idea if I got the endian swaps right. It outputs python and C syntax data statements to use in ktest and the firmware.
