I am testing out standalone mode and I got an error message with trying to install the auto generated artifact:

Mender Daemon was turned off on this built . Not sure why the update failed.

It looks to me like the image is too big for the partition. The Mender logs indicate the size of the update is 952107008 but your root partition is only 835.1M.

Can you post the output from “fdisk -l /dev/mmcblk0”?
Also the full size of the Mender artifact file would be helpful.

Don’t know what happened. The file size was 175 MB for the artifact. I did try to use the wrong artifact before which was the sdimg but it failed. I reflashed and been testing the upgrade process. So far the upgrade seems to be working now. I increased the storage a bit too cause it seems to be a problem in general.

Thanks
