Updating 6HC with SBC to a specific version number.

@techpriest-taro It should be on your Raspberry Pi's SD card. How are you connecting to the Raspberry Pi? SSH or VNC from another computer, or do you have a keyboard or monitor attached? Connecting to your RPi is covered here https://docs.duet3d.com/User_manual/Machine_configuration/SBC_setup#h-5-accessing-the-sbc-through-sshvnc
If using the RPi directly, or using VNC, you should be able to browse the RPi folder structure and find the .list file in /etc/apt/sources.list.d/.

If using SSH, you'll need to use terminal commands to change directory to it, eg

pi@duet3:~ $ cd /etc/apt/sources.list.d/
pi@duet3:/etc/apt/sources.list.d $ ls
duet3d.list  raspi.list  vscode.list
pi@duet3:/etc/apt/sources.list.d $ cat duet3d.list 
deb https://pkg.duet3d.com/ stable armv7
pi@duet3:/etc/apt/sources.list.d $

The 'cat' command shows the contents of the file.

@droftarts I have setup with a monitor currently.
The file says: "deb https://pkg.duet3d.com/ stable arm7" so it should update to 3.4.6? Because when i tried before it went straight to 3.5

droftarts

@techpriest-taro Are you sure? I've just updated my SBC, and it's updated DWC and DSF to 3.4.6.

Note that if you have updated the Duet board separately to a different firmware, it won't automatically reflash the firmware. Send M997 to update/downgrade the Duet to 3.4.6.

@techpriest-taro What DWC/DSF version is running? Like I said, if you send M997 it should update or downgrade the Duet firmware to the same version.

@techpriest-taro Well, that's weird. @chrishamm may need to help you with this one.

Ian

@droftarts alright, thanks for the help so far

droftarts

@techpriest-taro How are you going back to 3.4.4? By re-imaging the SD card? Try re-downloading the SD card image, see https://docs.duet3d.com/User_manual/Machine_configuration/SBC_setup#h-1-flash-the-image-file

@techpriest-taro You were on the unstable package feed so you need to downgrade the packages again to 3.4.6. See https://docs.duet3d.com/User_manual/Machine_configuration/DSF_RPi#downgrade-packages

techpriest.taro

@chrishamm The guys i work with also want to test 3.5 so that is fine, we just need a 3.4.6 as well.

chrishamm

@techpriest-taro If you need 3.5, you can upgrade again using the unstable package feed but to use 3.4.6 you need to downgrade as outlined in the docs. Under normal cicrumstances it isn't possible to have two different package versions installed at once.

droftarts

@techpriest-taro you could use two SD cards for the Pi, one with the stable feed (3.4.6) one with unstable feed (3.5). Swap as required. When you swap, run M997 to flash the appropriate firmware.
