Broken SD card boot loader.
I had a working RatOS 2.1 working on my RR.VCore3 and then whoops. I pulled the SD card while the Pi was still on. Now the Boot Loader does not work. The FAT32 partition and the EXT4 partition seem to be intact and I can get all the files from them on another linux machine.
So I:
1. Made a fresh SD card from the RatOS 2.1 image.
2. Booted the SD card on the rPi so the EXT4 partition would resized to take all (64 GB) available space.
3. Moved SD card to another machine and mounted the EXT4 partition.
4. Erased all files and directories from the EXT4 partition (RM -r *)
5. Copied all files, directories and file attributes from the original SD to the new EXT4 partition (CP -R -f -p -v Source SDDestination)
6. Inserted the new SD card in rPi and rebooted.
7. Booted rPi off the SD card ...

RatOS for Raspberry Pi5 ?
I have a working Ratos/rPi/Klipper running on a rPi 4.
I plan to replace the rPi 4 with a new rPi 5 8GB The printer is a VCore3.1 I went to https://github.com/Rat-OS/RatOS/releases and downloaded the latest (2024-07-27 RatOS-v2.10-RC2) image file.
The file was '2024-07-27-RatOS-2.1.0-RC2-raspberry-rpi32.img.xz' When the SD card is booted on the rPi 5 I get the following error: The installed operating system (OS) does not indicate support for Raspberry Pi 5 Update the the OS or set os_check=0 in config.txt to skip this check.*** Before I start modifying the OS or boot procedures, I wanted to check: Q. Does RatOS supports rPi 5? Q. Did I downloaded the right file? (should I have gone with armbian-CB1 over raspberry-rpi32?) Q. Should I be using Release Candidate 2.1 or one of the earlier releases? Any help will be appreciated.

How to configure a SuperPinda in RatOS & Klipper on a BTT Octopus?
I just upgraded from VCore3.0 to VCore3.1 on my VCore3-400 with a BTT Octopus. I am changing from a BLTouch to a SuperPinda too. I used the wiring diagram provided by RatRig & Mikkel (octopus_wiring.png) to wire the SuperPinda to the old BLTouch (J43) port. The diagram shows SuperPinda connected to J43 pins (#2 for 5V, #4 for Ground, #5 for Signal).
I have updated printer.cfg to include the config/steppers/ldo/42sth48-2504ac/2209/24v-1.6a-*.cfg file in the base setup.
[include config/z-probe/probe.cfg] I have also updated printer.cfg to and have "probe" configured. [probe] z_offset: 0.0 The SuperPinda probe is not working as expected so I pulled out a Volt/Ohm meter and started testing. The J43 #2 pin (second from the top) is providing 5V The J43 #4 pin is acting as ground. The J43 #5 pin is proving 3V when the probe is not attached. This does not seem right. It should be configured as an input that lets SuperPinda indicate when it is activated near a metal object. I see in the probe.cfg file that "pin: ^!probe_pin" is used to indicate the input probe pin. I can not find a reference to "probe_pin" and was just hoping that it is J43 #5. I am probably doing something wrong in the configuration and not setting the input pin (J43 #5) to be functioning as an input pin. How is this supposed to be done? What am I missing?
