Yes, I have other reports from the H9 not working well with backup-suite. One precondition seems to be an update of the BSP layer, which we currently are working on.
Am I correct is stating there is an issue with making backups via BackupSuite to ZGemma H9S? I saw something mentioned in the release notes on Github but could not find any more information on this. It creates the backup without any issue but does not restore. Using latest version of OpenPli.
