A 7I92TH/TF and a couple Mach 5 Axis BOBs could do this
(or even without the BOBs if you are careful...)

For this project 5 step/dir channels and some way to control a 3-wire RC servo motor.  I'd go with a 6 channel Mesa card if it wasn't a little pricey and out of stock.  

I've seen that setup you mention, or something similar in the LinuxCNC compatible board list.  Soldering doesn't scare me, code does, I'm a novice/intermediate coder. What I liked about the Mesa board I have on my router, it was virtually plug and play. 

If I can save a few dollars and learn something along the way, maybe I'll give this route a go.  I'll have to check into it.

No I didn't install it, just ran the script from the cloned directory ./rpi-eeprom-config.
Odd it partially works,
No cannot see the part to follow,
sudo apt install openssl python-pip fails but suggests
sudo apt install openssl python3-pip (success)
sudo python3 -m pip install cryptodomex
get message about externally managed environment and many options I cannot get to work.
Many thanks for this, but your plan A is looking far the best approach now.

Are you sure you're using the updated tool as that string doesn't appear in the file.

Did you follow this part
Requires Python Cryptodomex libraries and OpenSSL. To install on Raspberry Pi OS run:-
sudo apt install openssl python-pip
sudo python3 -m pip install cryptodomex

How are you calling the new utility ?
How did you "install" it ?

The string you're quoting is from an old version. I suspect you're still running the old version.

But...
so I run the updated tool, and the BOOT_ORDER info is displayed
I can apparently edit the line. ^O to write it, and ^X
but on exit, the very final kiss of doom is another message.
"This tool only works with a Raspberry Pi 4"

Back to plan a.

Ok, I have to clone the git hub repository and then run the updated tool from the cloned directory.

Not fighting me now.

Thanks

Hi all,
Long story short before my time on a tempermanent repair a wire bender was run on linuxcnc but they liked it and kept it (ran 7yrs no issues)
CMOS battery died, shut down cleaned and replaced.
PC boots up fine but linuxcnc won't open.
I've attached a few images of what I get from it when trying to run and open it and the debug file.
apologies for the images, offline machine and no USB to hand (trying to get them to 21st century).

I'm very basic with linux but the messing around has inspired me to grab my raspberry pi and to get playing again (for one never thought to look for a linuxcnc OS)
 

The link was to an updated version of rpi-eeprom-config.
The tool that you tried to use initially.

Sorry but cannot understand how the tools in the link are intended to be used.
So I'll do the "install the RasPiOS image, change from wayland to X via raspiconfig.
Then install the RT kernel & Linuxcnc."

As you first suggested.

Yeah I did and put forward a reason why. The 5 kinda broke a bit the RPi ecosystem for using the gpios, a lot of mature code won’t work on the 5.
Computation wise it is a beast for a SBC.

No idea.

I’d try the utility I linked to, plus install the extra bits mentioned at the “help section of the file” and see what happens.
But I’m sure you can update the eeprom as well using the above.

I prefer the rsapios as I don’t have issues with setting screen resolution and such.

What rod uses to create the images isn’t too bad, but misses some of the raspios utils.

Until there’s a linuxcnc spi driver for the RPi5 mines sitting in a draw as ATM it’s kinda useless, well for its intended use.

Ok Thanks.

But I could take a Pi5 version of the pieeprom.bin from the github link and place it instead of the current one?

Did anyone notice the RPI4/8gb is more expensive than RPI5/8gb ?
Still, at 90E it is to much.
BTW, sometimes, i get nice deals on that website, being a good customer n stuff, they are the only ones that actually work here, they deliver to my door and they never failed to deliver whatever i ordered there, even when the price listed was wrong , example got 2 of Creality CR-5 PRO for 656 Euro total when the price was $1300 in china, for one!
So i can justify a bit higher prices for sure, but not for RPI.
End rant.
So what are the prices for ethernet variants?

yeah there's a bit missing from the image, that makes life easier.
I found the easiest route was install the RasPiOS image, change from wayland to X via raspiconfig.
Then install the RT kernel & Linuxcnc.

One of the RPi5 threads has the info to do this.

There's an update version here github.com/raspberrypi/rpi-eeprom/blob/master/rpi-eeprom-config
