Duet3 Mini 5+ Firmware with SBC

I am in a total pickle now.
Last night installed a beta firmware due to assist DC42 in nailing down a issue.
I need to go back to 3.2.2 as it works.
Downloaded 3.2.2 and I get this error as a file is missing and I do not know where to find it on GitHub
M997 S0 Error: M997: Failed to find IAP file /opt/dsf/sd/firmware/Duet3_SBCiap32_Mini5plus.bin
Tried Sudo update commands because I am running a SBC, this does not work.
Please could someone help get back to where I was before I installed the Beta.
@paulhew Open a terminal on the SBC, either via SSH or locally on the Pi itself and run
sudo ln -s /opt/dsf/sd/sys/Duet3_SBCiap32_Mini5plus.bin /opt/dsf/sd/firmware/Duet3_SBCiap32_Mini5plus.bin
Then try to run M997 again.

@chrishamm Thanks for the speedy reply
I get this when I run the command.
i@RailCoreII:~ $ sudo ln -s /opt/dsf/sd/sys /opt/dsf/sd/firmware sudo: unable to resolve host RailCoreII: Name or service not known
@paulhew That message doesn't make a lot of sense, can you try to execute my updated command and see what happens? This is what I get:
pi@Ender3Pro:~ $ sudo ln -s /opt/dsf/sd/sys/Duet3_SBCiap32_Mini5plus.bin /opt/dsf/sd/firmware/Duet3_SBCiap32_Mini5plus.bin ln: failed to create symbolic link '/opt/dsf/sd/firmware/Duet3_SBCiap32_Mini5plus.bin': File exists
Unsurprisingly I get that error message because I'm already on the latest unstable version.
@paulhew The command christhamm suggested copies (actually, makes a symbolic link) of the /sys/Duet3_SBCiap32_Mini5plus.bin IAP file in the /firmware folder. RRF 3.3 uses the firmware folder for updates, so that's where the files need to be.
Instead of running this command, if you upload another copy of Duet3_SBCiap32_Mini5plus.bin in DWC, it should put it in the /firmware folder, then you can flash firmware. Because DWC 3.2.2 doesn't show the firmware folder, you can check the file is there by sending:
If you are on the 'unstable' feed, and you run 'sudo apt-get update & apt-get' from a terminal on the SBC, it will reinstall the beta firmware. To change back to the stable feed, see https://github.com/Duet3D/DuetSoftwareFramework#2-apt-package-feed
Basically, all you should need to do is edit the /etc/apt/sources.list.d/duet3d.list file. Open a terminal on the SBC, either via SSH or locally on the Pi itself and run:
sudo nano /etc/apt/sources.list.d/duet3d.list
Edit the only line, changing 'unstable' to 'stable':
deb https://pkg.duet3d.com/ stable armv7
Exit, save, then run
sudo apt-get update & apt-getto get everything back on the stable branch. You may still need to update the firmware on the boards, though.
