[Failed] notification of LSDK19.09 on LS1028ARDB

[yyu2]

Hi all,

I deployed the LSDK19.09 by flex-installer successfully. But after I start the system from SD card boot, it continuously report errors as below:

"

[FAILED] Failed to mount Mount unit for core, revision 6533.
See 'systemctl status snap-core-6533.mount' for details.

"

Do you have any idea?

Thanks

Hello Yi Yu,

Please refer to my attached log, booting the system with ubuntu:mate rootfs, I didn't reproduce your problem, the filesystem worked normally.

Please generate rootfs with the following command.

$ flex-builder -i mkrfs -r ubuntu:mate

$ flex-builder -i merge-component -r ubuntu:mate

$ flex-builder -i packrfs -r ubuntu:mate

Thanks,

Yiping

Hi Yiping,

I am sure about the procedures for deploying image on SD card, i.e.

-- flex-builder -i mkrfs -a arm64 -m ls1028ardb -r ubuntu:mate

-- flex-builder -c linux -a arm64 -m ls1028ardb -r ubuntu:mate

-- flex-builder -i mkbootpartition -a arm64 -m ls1028ardb -r ubuntu:mate

-- flex-builder -i mkfw -a arm64 -m ls1028ardb -r ubuntu:mate

-- flex-builder -i merge-component -a arm64 -m ls1028ardb -r ubuntu:mate

-- flex-builder -i packrfs -a arm64 -m ls1028ardb -r ubuntu:mate

The starting log is attached for your information. I did not find special difference from yours. Do you know what is the "Mounting Mount unit for core, revision 6533..."?

It seems that Kernel doesn't support squashfs, which is a requirement for snaps.

Hi Yiping,

I checked my linux config by "flex-builder -c linux:custom" and it showed "SQUASHFS [= y]" etc.

Could you help to check the your configurations to identify the difference from mine?

Thanks,

Please try to remove gnome-software-plugin-snap.

$ apt remove gnome-software-plugin-snap

Hi Yiping,

I tried the removal of snap plugin, rebuilt the rfs, linux kernel, mkbootpartition, merge-component, packrfs. But it did not take effect.

Thanks for your help
