I get greeted with either of these two screens when i try to boot up my machinee. its a fresh install of linuxcnc 2.93 on a raspberry pi 4 cm4 and a 7i96s, i have tried with other realeses but the issue remains the same. if it loads in to the program thee error messages pops up after a few seconds so not instant. Does anyone maybe know why or could point me in a direction because now im completly lost

@ccatlett1984 That was a bit of a pain to do, I would not recommend unless you have experience soldering and particularly desoldering.
I removed the factory Raspberry Pi two row header and soldered on a new stackable female header in it's place from the bottom. A
good tip to help with factory header removal is to pry off the plastic and desolder each pin one by one.
I want to say the exact part I used was a Pololu 2749, but check the dimensions of the header to be sure.
Thread update: MX4660 is gone, Thread can be locked no items remain.

Category: Installing LinuxCNC
Hi,
Thank you Alan for the original instructions, I have learned a lot from this post in the three days.
-- I got stuck: my kernel is SMP PREEMPT rather than SMP PREEMPT_RT.
I am Be Hai from Melbourne, Australia. I would like to learn LinuxCNC. Presently I know nothing about CNC or LinuxCNC.
I am a computer programmer. I am familar with Linux, and a tiny bit familar with Raspberry Pi 4 Model B: I have been learning basic physical computing with it, using the Python language.
I have spent more than a week learning about LinuxCNC, particularly how to install it onto a Raspberry Pi 4 Model B.
I spent the last three days exercising the instructions kindly posted by Alan.
⓵ I am using a clean and fresh Ubuntu 24.04.1 LTS (Noble Numbat) machine to do the build.
( I first started with Ubuntu 22.10 (Kinetic Kudu) and I went nowhere with this EOL version. )
⓶ The command
```
make RASPIOS_IMAGE_NAME=raspios_full_arm64
```
produces raspios_lite_arm64-Pi5.zip. I burnt this image into my Pi 4 anyway. And I have managed to get as far as to section 2.6 Install Mesaflash. There are error in between but I managed to find solutions for them.
LinuxCNC was installed, but I could not run it since there was no desktop.
⓷ Based on the instruction given in github.com/remusmp/rpi-rt-kernel
I replaced ```make RASPIOS_IMAGE_NAME=raspios_full_arm64``` with:
```
sudo make Pi4
```
This command produces raspios_lite_arm64-Pi4.zip. Applying this image, the kernel information reports only SMP PREEMPT:
```
uname -a
```
Output:
```
Linux picnc 6.6.31+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux
```
```
cat /proc/version
```
Output:
```
Linux version 6.6.31+rpt-rpi-v8 (This email address is being protected from spambots. You need JavaScript enabled to view it.) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29)
```
⓸ Interestingly, if I use 'Raspberry Pi OS (other)' from Raspberry Pi Imager as shown:
Then select:
```
Raspberry Pi OS Full (64-bit)
A port of Debian Bookworm with desktop environment and recommended applications.
Released: 2024-07-04
Online - 2.8 GB download
```
I also have the exact same kernel, but also with the desktop.
I am taking a break... I will try again to get RT going.
Thank you.

I need help about downloading config.txt to nvem v5.
I succeeded in downloading renoma nvem-rt1050 throw MCUXpresso IDE.
and received ping from nvem like below.
However, if I try to send config.txt, a timeout occurs.
As I see the letters in the temianl as below, I think the firmware was well put, but I don't know why it's not working.
