LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

I can run it under Windows now, but the graphical stuff does not work. 

In my case, it would be more convenient, as I only have Linux on the Raspberrry Pi 5.

Anyway, it is better that you use your time on the important stuff. The whole project is very impressive. Congratulation!!!

thanks
for the gui you need to install some python packages.


@all
oss-cad-suite stuff runs also on windows now

 

so it is not so hard to run the other toolchains also

EDIT: gowin works also
 

I am almost done. The Graphic in Overview, Hal and Axis works now.

rio.v and makefile OK.

One last issue: Warning: can not find toolchain installation in PATH: nextpnr (nextpnr-ice40)

Furthermore there is an error: loading joypad:: No module named 'fcntl'. No idea what I have to install here.

The toolchain for Tangbob has been installed and the PATH set. That warning is gone.

This error message is left:

loading board setup: Tangbob

PS C:\Users\MW\Downloads\riocore-using_os_path_join\riocore-using_os_path_join>

After pressing the button Generate it  fails (dir OutputTMP can be created, but dir Output somehow not)

Any ideas on the rio-generator (directory is correct and rio-generator is there)?

For the Windows convenience I'd still recommend a debian Virtual Machine for the Rio, toolchains, configs, and bitstream gen. They are easy and quick to put together. Only challenge I could think of is the bit file programmer, some VM aren't good friends with USB2.0/3.0 (e.g. Hyper-v).

It's been a decade since I've VM anything and so I wouldn't know which is best to use. Bet Virtualbox does it USB nowadays though.     

Thanks for pointing out. I will keep this in mind.

Though, I am still having a problem with the toolchain on the Raspberry Pi5 running Linux on it:.

Pressing the compile button:

rm -rf rio.fs rio.json rio_pnr.json rio.tcl abc.history impl gw_sh rio.tcl

Gives me following error:

/home/cnc-winder/opt/gowin/IDE/bin/gw_sh: 2: Syntax error: Unterminated quoted string
make: *** [Makefile:34: impl/pnr/project.fs] Error 2

Any idea what could cause this?
