There is a LOT of FUD going around in Steamboats group buy thread about there being no fully populated and working K16 boards. Could anyone put that to rest, or otherwise spell out where we are at? I'd like to have a quote to take back there and put this to rest. Thanks.
I do have a fully populated board v0.3.1 as of today, it's hashing fine with firmware set to 8 chips and with that cap near NOR replaced. Can do 350MHz per chip stable - around 2.8GH/s in total. BTW it's seems to be fine also with 220pF cap.
Will have to do some fixing, since couple of pins on some of the chips are not properly connected and then will try 16 chip firmware and report back.
But since the report lines from chips are shared between two banks, no problem should arise except from firmware issues.
Is the I2C code disabled right now? How to enable it?
I don't know. Focussing on getting the full board working.
About connecting two boards to CGM via USB. I found a workaround - running two CGMs with specified --usb option and with one board per CGM.
Just run ./cgminer -n, it will list all usb devices. Then fe. ./cgminer --usb 1:25 for first board and ./cgminer --usb 1:24.
