Hi guys. What's up with this development? Nothing has happened in a few weeks, is it dead?

ngzhang: Your miner board is very interesting! Do you have any real-world performance data? Is the board stable? What's the current consumption on the FPGAs? I'm looking forward to the schematics and other files on that board.

These days, I fixed some bugs on the hardware and relayout the PCB. Another 10 boards are under manufacturing. Coming out soon.
On the firmware side:
With a single FPGA running LX150_makomk_Test's code, a speed of 120MH/s perFPGA has been reached. looks very stable. We only use a -2 device.
with ourselves' UART communication mining code, a test version could mining @ 50MH/s and not very stable, maybe there are some P&R problems. Because lack of time, we just checked the function, it works.
Now we are testing the the FPGA mining chain, this part is still under coding.
The mining core is the most important part of this project, so after finish the mining chain architecture, we will put 100% efforts on this core.
Correct makomk's core use SLR16s to save resources, but this cause a terrible P&R difficulty. But if don't use the SLR_16s, there are not enough registers. Solve this conflict will lead a single FPGA to 250MH/s at least.
