I will try and help because it looks as though nobody may have any experience with CubeIDE (myself included)
I have been focusing on using the latest linuxcnc installer release (2.9) on PC hardware and have so far got every debug probe I can get my hands on working with it.
I am finalising the entire install process (using pc hardware) including getting wifi working and installing ProbeBasic. I haven't finished it yet but here is my first draft and it has worked for me 100% of the time. I haven't had the time yet but you could try and test this with the Live Installer if you didn't have spare pc hardware to install on and see if it works also.
Flashing and getting remora running are steps 6, 7, 8 and 9
If anyone does try this and have or notice errors please let me know so I can test or rewrite it. If you test on different hardware and have success please let me know so I can include it. If you have issues let me know and I will try and help but I am very busy and a beginer myself so don't expect fast miracles.
Cheers.
### FLASHING REMORA GUIDE ###
WORKS WITH STANDARD UNMODIFIED STLINK
CLICK THE SPOILER
### DRAFT ONLY ###

#2 - Updating to 6.3RT Kernel (Optional)
#3 - Fix latency issues with Realtek NIC and install WIFI drivers (Work in progress. Optional)
#4 - Install ProbeBasic (Optional)
#5 - Installing PYOCD and TFTPY
#6 - Setup debug probe
#7 - Flash firmware to EC500 (RT1052)
#8 - Install Ethernet component

### Please report errors to Cold Turkey ###
#1# DOWNLOAD AND INSTALL THE LINUXCNC ISO #
#1 Open Console
sudo apt update
sudo dpkg -P raspi-firmware
sudo apt upgrade
sudo apt-get install geany ethtool grub-customizer usbutils git
#2# Upgrade Kernel to 6.3RT OPTIONAL ##
#2 download linux-headers and linux-image from here: https://drive.google.com/drive/folders/1NzQIHnf9M_cHzuZCqSldVFGschOOxaER
#2 Unzip files to folder.
#2 Open terminal in that folder and run the code below (note: pressing (tab) lets linux autocomplete the line for you to save typing)
sudo dpkg -i linux-headers(tab)
sudo dpkg -i linux-image(tab)
sudo grub-customizer
#2 Using grub customizer window: Delete the kernels that aren't 6.3 (should have two 6.3 kernels left) OR Make the new 6.x kernel the default. Eg move to the first entry and then REBOOT
#2 Check our new kernel is the default - Open Console
uname -v
#2 Should give result like: #2 SMP PREEMPT_RT Wed Dec 14 00:49:27 AEST 2022 (Example Only)
uname -r
#2 Should give result like: 6.3.0-rt5-linuxcnc-rt (Example Only)
#3# FOR REALTEK NIC ETHERNET LATENCY ISSUES - UNFINISHED WORK IN PROGRESS - OPTIONAL ###
#3# For Realtek usb WIFI adapters - skip first part of step 3 - Tested - Working only with some dongles - OPTIONAL
#3 open console
ip a
#3 Look for altname (should look like enp0s31f6)
sudo ethtool -i (name here)
#3 CHECK DRIVER and FIRMWARE MATCH = SOMETHING LIKE r8169 (IF NOT THEN CONTINUE)
sudo geany /etc/sources.list
#3 Comment out CD or DVD #
sudo apt-get update
sudo apt-get install (driver you need)-dkms
(EXAMPLE) sudo apt-get install r8168-dkms
sudo reboot
#3 CHECK AGAIN
sudo ethtool -i (name)
#3 Get Realtek Wifi working - Tested - Works with some of my usb wifi dongles but not all - Make sure you have usbutils installed from step #1
lsusb
sudo apt-cache search firmware-realtek
sudp apt install firmware-realtek
sudo git clone "https://github.com/RinCat/RTL88x2BU-Linux-Driver.git" /usr/src/rtl88x2bu-git
sudo sed -i 's/PACKAGE_VERSION="@PKGVER@"/PACKAGE_VERSION="git"/g' /usr/src/rtl88x2bu-git/dkms.conf
sudo dkms add -m rtl88x2bu -v git
sudo dkms autoinstall
sudo reboot
#4# INSTALL PROBE BASIC - OPTIONAL ####
#4 Open Console
sudo apt install python3-qtpyvcp
sudo apt install python3-probe-basic
#5# PYOCD and TFTPY #####
#5 Open Console
sudo apt install pipx
pipx ensurepath
#5 Restart Console
pipx install pyocd
pipx ensurepath
pip3 install tftpy --break-system-packages
#5 Restart Console
#6# SETUP DEBUG PROBE TO WORK WITH PYOCD ######
#6Plug in debug probe and open a terminal
pyocd list
#6# If you can see your probe then skip step 6 and continue with installing remora > step 7
#6# If you can't see your probe then we need to create or modify the *.rules in the udev folder: Download these rulesets: https://github.com/pyocd/pyOCD/tree/main/udev
#6# Navigate to your downloaded folder and open a console
#6# With your debug probe plugged run the following - Make sure you have usbutils installed in step #1
lsusb
#6# Identify your probe: CMAS, CMSIS, STLINK, etc. Identify Address (EXAMPLE: Bus001 Device007)
#6# Run the following in terminal with correct device address (EXAMPLE: Bus001 Device007)
udevadm info -a -p $(udevadm info -q path -n /dev/bus/usb/001/007)
#6# Read through generated data and find the following fields and copy their "values". ("numbers" below as example only)
#6# SUBSYSTEM=="usb"
#6# ATTR{idVendor}=="6666"
#6# ATTR{idProduct}=="9930
#6# Press q when you have what you want to quit the search
#6# In the folder with the rules you downloaded, find the right ruleset (STLINK, etc) open in notepad
#6# If you cannot find a rule with values matching your values then add it to the bottom
#6# (EXAMPLE) SUBSYSTEM=="usb", ATTR{idVendor}=="6666", ATTR{idProduct}=="9930"
#6# Open Terminal in folder containing your new modified rules and run
sudo cp *.rules /etc/udev/rules.d
sudo udevadm control --reload-rules
sudo reboot
#6# Open terminal - with debug probe plugged in run
pyocd list
#6# You should now see your debug probe.
#7# FLASHING REMORA FIRMWARE TO EC500 ##
#7# DOWNLOAD REMORA CPPMAIN FROM GIT##
#7 Plug your debug probe into the EC500 header pins and power the EC500
#7 Open console in the downloaded folder containing Remora Firmware and run
pyocd flash remora-rt1052-3.1.2.bin --target mimxrt1050_quadspi
#7 Once finished wait a 10 seconds and then power cycle the EC500 (IMPORTANT NOTE: POWER CYCLING THE EC500 TOO FAST CAN CORRUPT IT REQUIRING FIRMWARE REFLASH, ALWAYS WAIT A FEW SECONDS BEFORE POWER DOWN AND POWER UP)
#8# INSTALL ETH COMPONENT
#8 Find downloaded components folder containing remora-eth.3.0.c and open a console here - run
sudo halcompile --install remora-eth-3.0.c
#9# Flashing a CONFIG to the EC500 ##
#9 Plug in ethernet from PC to EC500 - Set IP address manually with range of (10.10.10.*) DO NOT USE (10.10.10.10)
#9 With EC500 powered, navigate to your folder containing your CONFIG (usually your machine config folder) and open console in the location - run
ping 10.10.10.10
#9 You should be seeing results from the EC500
#9 Ctrl-C to close ping - run
python3 upload_config.py config.txt
## FINISHED ##
## If you run your HAL and have an error - Check your .hal is loading the eth3.0 component and not the remora.nv component##

I saw in previous post you have done full chip erase with pyocd, when I tried this I get a no ACK error , did you put jumper on the boot pin or else , can you share your procedure for full chip erase, I was only able to do it in mcuexpresso. I also put bad config in it. Thank you very much for the tutorial for flashing it from linux computer, i'm gonna give it a try.

From memory in Pyocd to erase the chip run the following:
pyocd erase --chip --target mimxrt1050_quadspi
If you have another probe but it isn't recognised by pyocd then look through my previous post. There is a step to get it working.
P.S. No, I didn't use a jumper

I had the ACK error show up on a modified STlink after having used it multiple times within the previous hour, went back to a standard ST and had no further issues.
You can try leaving the STlink and EC500 depowered for a while. I came back the day after I had the issue and got it to flash once more before the error came back again.

The biggest issue I found with linux and pyocd is that it doesn't give permission for pyocd to access the usb device. There is a step in my post to allow this. It may work with versions of linux outside of the linuxcnc distro
I focused on getting it working using the linuxcnc install because I figured it's what the majority of us would be using and it's nice to make everything work using just one computer. Good luck.

There is no reason to use Linuxcnc installation for anything except drive the CNC machine.I focused on getting it working using the linuxcnc install because I figured it's what the majority of us would be using and it's nice to make everything work using just one computer. Good luck.
There are many Linux distros better suitable for programming microcontrollers.
You can install many OS on one computer, and use this, that is better for you do at the moment.
Notice, many tools (especially python based) are version sensitive and can works only with specific distro.

And yet there are still heaps of people in this thread struggling with flashing Remora to the board and no clear start to finish documentation that works 100% of the time. A lot of people don't want more than one operating system on their computer, especially if they are only going to use it once for this job only. Why learn about more distros of linux when we can just use linuxcnc since that is what we have already and it also works?

If there is a better way of doing it and since you obviously have more experience than I do, how about you contribute and write a guide to help all the people having issues?
