Ok the fix was pretty simple and i have pushed it to 2.9 and master.

i don't know when a new release of 2.9 will be as there was just one done.
it is possible to add a customization to your current system to fix if you are interested or you can edit a file on your system to fix it.

Just completed a successful installation of LinuxCNC version 2.9.8 on a Pi 4 with 4 gig of RAM.

Thanks to forum user "NWE" for recommending the version to download, named below:
2026-01-21-raspios-lcnc-2.9.8-trixie-arm64.zip

After downloading and using balenaEtcher to flash a 256Gig micro SD card, it booted to a Debian 13 Trixie style desktop and opened a "boot wizard".  After creating an account, the wizard recommended loading updates.  There was trouble after that, the login dialog box wouldn't accept any userids/passwords.

After rebooting and choosing NOT to load s/w updates, everything worked fine.  

I'm using LinuxCNC to retrofit a 1990's vintage Intelitek ProLight 3000 CNC lathe.  The original lathe was controlled using proprietary h/w and PC-based s/w.  I acquired a Mesa 7i76EU board as recommended by Mesa Technical Support so the journey is underway.

I see that LinuxCNC has a Mesa board config tool so I'll use that.

Any advice or coaching for me as an absolute LinuxCNC newbie is much appreciated.

 

I try in the while a fresh 2.9.8 installation and the problem persist but it returns an a error window with this messagge:
"Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/qtvcp/widgets/basic_probe.py", line 261, in probe_btn_clicked

And the attached report once I close the window.

I have used ST-link for EC500 programming (MIMXRT1052 too) but under Linux and with OpenOCD.
I don't know is ST software compatibile with MIMXRT1052 (I suspect not), but there is no reason to try this if OpenOCD works well.

That´s it. Thank you very musch Crhis!!!

I also see that problem is master branch.

So I won´t resolve the problem updating anything, it´not a version issue.

Thank you.   
For a Rtelligent R6L028E I get to the installation stage where I can test for:

ethercat slaves -v      
and
ethercat pdos          
but
ethercat sdos        returns nothing. Is this to be expected or am I doing something wrong ?

Ok I see the probe screen is showing but the tab selected is main.
I also see that problem is master branch. I'll investigate.

ST-LINK (the hardware, at least) actually works fine for programming/debugging other vendors' ARM-M series ICs- used it a lot in the past for Nordic's nRF52 series. I was using OpenOCD, not the ST-LINK SW, though, and have never tried on a Cortex M7.

First thing is to triple-check connections- that you don't have wires plugged in off-by-1 in a connector. Also that everything is actually getting power (and what voltage it's using- 1.8V, 3.3V, etc.). I don't know where you got that pinout, but making sure it's correct wouldn't hurt.

It's been a while, but IIRC some ST-LINK models require you to have a target voltage reference connected- that may well be what the "???" pin is. It may help to probe that pin and figure out what it is and post exactly which ST-LINK you're using- official ST-LINK V2, some knockoff, the ST-LINK built into an STM32-Discovery board, etc. Again, it's been a while, but IIRC some of them have limitations I don't remember off the top of my head- might be they only worked at 3.3V and we were using 1.8V systems? My recollection is that the official ST-LINK V2 (not the isolated model, not the mini model) is the "good" one that works with everything.

You can also try reducing your SWD frequency to see if that helps, but I wouldn't be super optimistic.

Finally, I see in the MIMXRT1052CVL5B datasheet "Support for 5-pin (JTAG) and SWD debug interfaces selected by eFuse". I didn't probe further, but that implies that SWD could actually be disabled.

Good evening 

I've been using this iso successfully for a while now, i picked up a nice touch screen that works, but would work a lot better if i installed the displaylink drivers. Problem is that when installing this, i get an error that the linux headers are missing. 

Ive tried many of the usual commands to load the headers and nothing seems to be able to find the matching file. Have you got any insight or suggestions? 

If you would like specific error messages i can go through the motions and record these for you. 

Cheers!

i'm not into this stuff, but why would an ST programming utility connect to an NXP chip?

Hi Chris.

I tried creating a Probe routine in MDI mode, just in case I was doing it manually and it was my mistake. I'm getting the same problem in both MDI and MAN modes. I've attached screenshots from both modes.

Thanks a lot.

No double posting, please continue in the thread linked above.

the whole connection thing was already working on mesaflash and mesact, i could confirm with mesact, every test was a success. But Linuxcnc would fail, In the end I had to click on the network button top right and then it worked.

As for now i´m okay. Sorry for the rant, but I was used to it being easy setup with Pncconfigwizardo

You need to configure the network on the host for the Mesa card.

Also 192.168.1.121 is not suggested for LinuxCNC use as it's  in
a commonly used NAT range.

Suggested setup is to use the 10.10.10.10 address on the Mesa card
(via the IP address setup jumpers) and set  a static host address of
say 10.10.10.100/24.

At this point you should be able to ping the Mesa card:

ping 10.10.10.10
