RPI4 Raspbian 64 bit & LinuxCNC

I understand, I like challenges. As long as people are willing to help me I am willing to keep trying. I am not ready to start running my mill yet so it is not slowing me down and I am learning so its all good. If anyone is up for the challenge I am game.

Hey All I think I was able to build it on a fresh OS install.
Now I am stuck at the Install phase.
I used elovalvo procedure with Andy's Clone file.
I used the extended wget as elovalvo cautioned me on.
Looks like it is not pointing to the correct location?

This is the error now.

Thanks again for all the support!

Is there a specific reason you are building it all from scratch? elovalvo posted some premade images, they make it pretty easy.

The limit of 3g of ram isnt that big a deal if your only running linuxcnc, I operate without issue. The 64bit does have lower latency, but I also dont run any ethernet boards.

The first, downloadable at the following link:
Linux 5.4.61-rt37-v8 - LinuxCNC 2.8.1
is based on Linux raspberrypi 5.4.61-rt37-v8 with PREEMPT_RT and LinuxCNC 2.8.1

The second, downloadable at the following link:
Linux 5.10.25-rt35-v8 - LinuxCNC 2.9.0~pre0
is based on Linux raspberrypi 5.10.25-rt35-v8 with PREEMPT_RT and LinuxCNC 2.9.0~pre0

Both can be installed with:
Raspberry Pi Imager
that in the latest version (1.6.1) allows you to modify some startup parameters by using hidden commands that can be accessed with the CTRL+SHIFT+X key combination

I checked operation on Raspberry Pi 4 with 2GB and 4GB.
I don't have a Raspberry Pi 4 with 8GB, so it would be interesting to check how it works.

Thank you,
I have tried that but I cannot figure out how to access the storage. no storage option shows up. Do I need to add the images on a different computer? Currently I built it on the RPi that I am going to run LinuxCNC on?
Also thanks for the Ctrl + Shif +X info I tried to change a few things but still no storage options.

Thanks I tried that one as well I get the same results.
