Yeah had a foreman say that to me when I was just on time for a job, thought it was kinda funny.

Yep that should work with openfpgaloader

There are other switches you can use. Best to read the docs github.com/trabucayre/openFPGALoader

Just uploaded a new IceStudio file for a stepgenerator; this file can be easily converted to a Verilog file and subsequently added to the firmware.

Why not using Pluto-Step? I didn't like the fact it does not take acceleration into account on the FPGA. The standard LinuxCNC stepgen does take acceleration into account. So the code of make_pulses is converted to something a FPGA should easilty run...
 

You are doing a great job making this more modular and extensible! Super cool to see it getting pieced together--looking forward to the step generation code. At that point it would have all of my immediate needs covered. I also ordered some SN74CBT3245APWR to replace on the board for input pins, ALittleOffTheRails convinced me . It would be silly not to make use of some of these pins for inputs as well down the line.

I did some further testing with the older version of the gateware and im still suspect of the buffer depth (1060) being too deep as most the liteeth docs show max of 255, ref; github.com/enjoy-digital/litex/blob/mast...ote/etherbone.py#L92 . I was able to do a test to make sure that the board in general works just fine running something like github.com/enjoy-digital/liteeth/blob/ma...ch/test_etherbone.py and it will happily read/respond to the registers in this case.
