Raspberry Pi 4 Tutorial - fatal error

Back again after trying to move forward with the dpkg and build part of the tutorial install. Keep hitting brick wall...should I start over...back up to where kernel installed ok???? Or other. Here's a pic of what's on file but build fails ...sorry if too inexperience d to ask better question.

Good evening.

I'm raising an error at the stage where LinuxCNC is installed.

I would greatly appreciate if anyone could help me understand the error and how to proceed.

Command entered:
The following error raised:
dpkg-buildpackage -us -uc -ui failed

Here are more messages leading up to the error:

As an update, I managed to get LinuxCNC to install without error. I'm only guessing, because I am new to all this, but this time I used the image of Raspbian Lite to which John has linked in his instructions. In the failed attempt, I used the latest Raspbian Lite version shown on the RPi site.

Just a guess.

Thanks Andy. I may play with it, as I work toward understanding how it all works.

Thanks,

Hi Andy / John,

Three attempts now, and still failure. (please help)
I am trying to install on a Raspberry Pi 4B 8GB. Everything looks successful until the reboot after the OpenBox install.
when booting up the Raspberry pi will not see the keyboard and mouse, (I think the USB ports are not loading)
the error is
[ 22.407948] xhci_hcd 0000:01:00.0 can't setup: -110
[ 22.408117] xhci_hcd 0000:01:00.0 init 0000:01:00.0 fail, -110

strangely enough I let it continue, and get the debian splash screen and logging in from ssh I can still remote into the pi. I just cant get the keyboard or mouse back. (They work fine with standard installs/tests after this)

some of the differences I get which may be a clue:
when building the preempt rt kernel, what reports back is: DEPMOD 4.19.71-rt24-v7l+
which is not exactly as in the documentation (# should report back DEPMOD 4.19.59-rt23-v7l+) but I just assumed that this might be the latest version - so I didn't think it was significant.

The other thing I am doing different is that I am using a windows machine to do the ssh remote copy/paste of the instructions. Is this wrong? it seems to work well.


I did read the whole thread looking for users with similar issues and didn't see any but sorry if this is a repeat question. I looked for other ways to install linuxcnc on a raspberry pi. but your instructions look the best so far for a novice like me and I'd like to follow through.

I have tried the sd card beta image that Andy mentions but it also locks up my keyboard and mouse as well, but loads all the way though to the desktop environment.

(keyboard and mouse work fine after all this with standard installs of Raspian)

Thanks for your help in advance.

Thanks!
I was suspecting it was missing steps and I did see the raspberry pi thermometer lite up during the attempts - so I think you might be on to something.

I tried to run the instruction set without the -j4 parameter in the make commands
make -j4 zImage
make -j4 modules
make -j4 dtbs

It ran a lot slower, (I was hoping cooler and no missing steps) but this did not resolve the issue.
After reboot It repeated the same error (can't setup -110)

Thanks for your input

Hey folks,
I'm just starting down the Rpi4 linuxcnc with mesa 7i96E path and so far I'm flopping.
All looked good with John's instructions, except the very last part on the Preempt RT Kernel page. When I rebooted, I got many errors and pi lockup, no SSH.
I've attached an image of what happened when I rebooted after altering the /boot/cmdline.txt

The only thing I can think that I may not have done is added the "-n" to the reboot.
Any thoughts?
I'll add that I also tried the latest .img file on the linuxcnc repository, but I get wrong CPU 0 not supported error. I flashed the micro SD with the latest .img from 9-14.

If anyone has other suggestions, I'm all ears. I'd really love to use the pi4 for this next LinuxCNC build, but I may be suffering an early defeat.
Thanks,
Tyler
