@chrishamm No worries, glad I could help!

Unsure who @owend is, are they one of the developers?

Tl;dr: Firmware on Duet 3 Mini 5+ with SBC wouldn't update from 3.2.2 -> 3.3RC1 until I copied the IAP .bin file and the .uf2 file from /opt/dsf/sd/firmware/ to /opt/dsf/sd/sys/? (Also, possible bug in reprapfirmware.postinst script - chown dsf:dsf wildcard doesn't match .uf2 files)

Hi there,

I have a Duet 3 Mini 5+ with a Raspberry Pi 4 SBC connected in the usual way (SPI over the included ribbon cable).

I attempted to upgrade from 3.2.2 to 3.3-rc1 using the following command (after changing "stable" to "unstable" in the sources.list.d/... fragment file)...

root@duet3-cr10spro:~# apt-get install duetcontrolserver=3.3-rc1 duetruntime=3.3-rc1 duetsoftwareframework=3.3-rc1 duettools=3.3-rc1 duetwebcontrol=3.3-rc1 duetwebserver=3.3-rc1 reprapfirmware=3.3-rc1-1

root@duet3-cr10spro:~#

... but found that, despite the message "Sending update request to DCS... Done!", the firmware was still showing up as 3.2.2 in the DWC UI even after doing an M999 to reset the board:

Looking at the postinst script for the reprapfirmware deb package, I notice that it contains a line chown dsf:dsf /opt/dsf/sd/firmware/*.bin...

root@duet3-cr10spro:~# cat /var/lib/dpkg/info/reprapfirmware.postinst
#!/bin/sh

# Adjust file permissions
chown dsf:dsf /opt/dsf/sd/firmware/*.bin

# Instruct DuetControlServer to update the firmware
/opt/dsf/bin/DuetControlServer -u

exit 0
root@duet3-cr10spro:~#

...but looking in /opt/dsf/sd/firmware/ there is one file that has a filename not ending in .bin: Duet3Firmware_Mini5plus.uf2, which oddly enough has owning user/group root:root:

root@duet3-cr10spro:~# ls -l /opt/dsf/sd/firmware/

However, even if I manually issue the following commands...

root@duet3-cr10spro:~# chown dsf:dsf /opt/dsf/sd/firmware/Duet3Firmware_Mini5plus.uf2
root@duet3-cr10spro:~# /opt/dsf/bin/DuetControlServer -u
Sending update request to DCS... Done!
root@duet3-cr10spro:~#

...this still doesn't seem to help, though?

I modified /usr/lib/systemd/system/duetcontrolserver.service to have "-l debug" on the command line...

root@duet3-cr10spro:~# cat /usr/lib/systemd/system/duetcontrolserver.service

...and then ran systemctl daemon-reload followed by systemctl stop duetcontrolserver.service and systemctl start duetcontrolserver.service.

Looking in the output of journalctl -u duetcontrolserver.service I see that it is complaining about being unable to find Duet3_SBCiap32_Mini5plus.bin...

...despite that file existing just fine (and not being the file with the wrong(?) user/group owner)?

I tried various ways of invoking the update, including running M997 S0 from the DWC UI, or /opt/dsf/bin/DuetControlServer -l debug -u with or without duetcontrolserver.service running.

Whichever I do, I get:

Error: M997: Failed to find IAP file Duet3_SBCiap32_Mini5plus.bin

As a test, I changed back the ownership of Duet3Firmware_Mini5plus.uf2 to root:root, then made a copy of Duet3_SBCiap32_Mini5plus.bin in /opt/dsf/sd/sys/.

After starting DCS up again with systemctl start duetcontrolserver.service, I did:

root@duet3-cr10spro:~# /opt/dsf/bin/DuetControlServer -l debug -u
[info] Settings loaded
Sending update request to DCS... Done!
root@duet3-cr10spro:~# 

and then looking at the output of journalctl -u duetcontrolserver.service, now this time I get a complaint about Duet3Firmware_Mini5plus.uf2 being missing:

May 02 21:53:28 duet3-cr10spro DuetControlServer[9822]: [debug] Waiting for execution of M997 (prioritized)

May 02 21:53:28 duet3-cr10spro DuetControlServer[9822]: [debug] IPC#11: Connection closed

Ditto if I try through the DWC UI:

M997 S0
Error: M997: Failed to find firmware file Duet3Firmware_Mini5plus.uf2

Now let's try changing the owner back to dsf:dsf again (as I think it should be, rather than "root:root" as it was when I found it):

root@duet3-cr10spro:~# chown dsf:dsf /opt/dsf/sd/firmware/Duet3Firmware_Mini5plus.uf2
root@duet3-cr10spro:~#

... and triggering an update again...

root@duet3-cr10spro:~# /opt/dsf/bin/DuetControlServer -l debug -u
[info] Settings loaded
Sending update request to DCS... Done!
root@duet3-cr10spro:~#

... and looking at the journalctl output...

...it still complains?

Okay, let's try the same thing we did for the IAP image - copying it into the sys directory:

... which seemed a bit more promising, as it took maybe 20 seconds rather than coming back instantly, so let's check the journalctl logging...

[... snipped rest of output as it was irrelevant ...]

I'm not actually sure what the take-away is here... was it expected that I had to manually copy the files from /opt/dsf/sd/firmware/... to /opt/dsf/sd/sys/...?

Should the DuetControlServer have "known" to look in /opt/dsf/sd/firmware?

Anyway, I just thought I would report this, having gone to the trouble to investigate.

Thanks,

Hazel
