Will this bitstream also work with the "classic" Icarus Boards ?
The makomk bitstream don't work for both Icarus FPGA's, but you can try a mix of original icarus bitstream on the first fpga and makomk to the second one or vise versa. This could work.
The makomk bitstreams have the RX/TX changed for the second fpga, as this was the fault of CM1.
