Until the maintainer of Litex-cnc look into this (have you reported it on github?), you can install OSS-cad manually to get you going. Ensure your path is set.

$ mkdir oss-cad
$ cd oss-cad
$ wget github.com/YosysHQ/oss-cad-suite-build/r...nux-x64-20231017.tgz
$ tar -xvf oss-cad-suite-linux-x64-20231017.tgz
$ export PATH="/home/user/path-to/oss-cad-suite/bin/:$PATH"

You cannot run LinuxCNC on a 386, the memory model is different on the 386 from the 486, Pentium, etc. CPUs. But, you say it is an X64 i7 CPU. Something must have gotten seriously fouled up during the OS install, or during the setup for the OSS-Cad-Suite.

Try this:
litexcnc install_toolchain --user --architecture x64 --os linux

I try this method, but no working...
$ mkdir oss-cad
$ cd oss-cad
$ wget github.com/YosysHQ/oss-cad-suite-build/r...nux-x64-20231017.tgz  (I updated the name)
$ tar -xvf oss-cad-suite-linux-x64-20231017.tgz
$ export PATH="/home/user/path-to/oss-cad-suite/bin/:$PATH"

And I try this:
litexcnc install_toolchain --user --architecture x64 --os linux

It's work!!!

So, next problem..
I try flashing the FPGA (5A-75E v8.0) widt FT2232 modul, but always get this error:

nc@cnc:~/Downloads/proba2$ openFPGALoader -d /dev/ttyUSB0 -f prob.bit
write to flash
Jtag frequency : requested 6.00MHz   -> real 6.00MHz  
mpsse_write: fail to write with error -1 (usb bulk write failed)
mpsse_read: fail to flush buffer with error: -1 (usb bulk write failed)
JTAG init failed with: Unknown device with IDCODE: 0x1954fc56 (manufacturer: 0x62b (), part: 0x4a vers: 0x1

What is the problem?
 

Prolly just because ya forgot to make a wish and didn't crossed your fingers... stuff's picky sometimes.
$ sudo openFPGALoader --unprotect-flash -c ft232 -f prob.bit

I tried but no change. (I see the /dev/ttyUSB0..3 the ftdi2232 modul)

$ sudo openFPGALoader --unprotect-flash -c ft232 -f prob.bit
write to flash
unable to open ftdi device: -3 (device not found)
JTAG init failed with: unable to open ftdi device

If I try this:
$ sudo openFPGALoader --unprotect-flash -c ft2232 -f prob.bit
write to flash
unable to open ftdi device: -3 (device not found)
JTAG init failed with: unable to open ftdi device

$ sudo openFPGALoader --unprotect-flash -d /dev/ttyUSB0 -f prob.bit
write to flash
Jtag frequency : requested 6.00MHz -> real 6.00MHz
mpsse_write: fail to write with error -1 (usb bulk write failed)
mpsse_read: fail to flush buffer with error: -1 (usb bulk write failed)
JTAG init failed with: Unknown device with IDCODE: 0x8d1d2c56 (manufacturer: 0x62b (), part: 0x68 vers: 0x8

If it doesn't take the -c ft232 argument I suspect there is a driver issue.

$ sudo dmesg | grep FTDI
Post output. And while there enable --verbose-level=2 (or 3, forgot)

I'll try it tomorrow.

May be necessary external resistor? (4.7k)
TCK = Pull-down
TMS = Pull-up
TDI = Pull-up
TDO = Pull-up

No pullup/down required. Straight up ft232's AD0~AD03 to jtag inputs. Inserting a fully functional ft232/driver output below for your ref. Good luck with making this work.
