I tried on a different board with the same results. 140 makomk bitsteam works on fpga 0,3 just like twin_test. It
does not work on fpga 1,2. I double checked the comms. I can only think I'm making a procedure error.
For programming:
SW6 1 off, all else on
SW1 3 off, all else on
SW2,5 all on
SW3,4 2 off, all else on
For mining:
SW1 all on
no other changes
I think you need to program all 4, but only address 2 COM ports as it drives them as a pair in this mode.
Am I wrong? I couldn't get this bitstream to work better than twin_test either.
It either failed Icarus detect in CGminer or hashed too slow, or not at all.
I had the same results, if I read correctly I think ebereon uses a jtag cable, maybe that makes it work? Im just using the usb cable.
