``` you in https://bugs.libre-soc.org/show_bug.cgi?id=511#c4
don't know.  can you at least run it, successfully?  i'm staring at
the c4m files and not spotting anything obvious.  the c4m cocotb unit
tests clearly work.

this is the equivalent test:

https://gitlab.com/Chips4Makers/c4m-jtag/-/blob/master/test/nmigen/cocotb/controller/test.py#L97

the ioconn pads/core values should match up, and they don't.
```

I took the above to mean you wanted my to try to run
https://gitlab.com/Chips4Makers/c4m-jtag/-/blob/master/test/nmigen/cocotb/controller/test.py#L97,
but I guess I have misunderstood you once again!! Grrrrr.... SO. MUCH.
TIME. WASTED. I'll go bald from all of the hear-tear this has caused.

Ok will do. Perhaps I should have just asked this from the start
instead of trying to figure out how to do it, what are the exact
instructions for setting up this, as well as the litex/fpga stuff. Got
my ulx3s ecp5 and ST-Link V2 JTag usb debugger yesterday and am
currently trying to set it up... the ulx3s manual is so confusing :(
