The log files are not much help as there is only one entry in the ma.log:
INFO 2020-11-30T09:58:50,027 (com.serotonin.m2m2.Main.main:121) - Starting Mango 3.7.7 with Schema Version: 29
Let me know which ones you'd like to see the contents of and I'll post it here.
@mseverin did you get any further? That last log message looks like somehow you assigned the points from an Ascii File data source to an Internal Data Source. I am not aware how that could happen unless you are using the REST api and your own code, and even then this should not be possible or have executed some SQL commands on the database to move data points around?
@techalton Phillip does not work at Infinite Automation any more.
Can you please clearly describe what you are trying to achieve. Please detail your current setup (details about your dashboards, data source, etc) and what exactly is not working the way you want.
Alas, that is absolutely no information about the problems you are having. In your emailed variant of this question, I replied all one must need do is connect the RS-485 port (if it's an RS-485 serial network), configure the BACnet local device via either the system settings page in the old UI or the local devices config in the new UI (maybe have to enable in the edit menu page and be on an up to date version), and then create a BACnet MS/TP data source on the data sources page.
But again, without a specific question or really any hint of the problem, I don't know what help to offer.
I can't say for sure what the issue would be. If you're transferring the image from one eMMC to a newer eMMC it's possible you'll need to update Linux before it will boot. There are also some hidden boot sectors that can cause issues between eMMC board revisions. Likely if you put this question to the Odroid forum, they would want to know the color of the eMMC to find the revision number and the version number / type of operating system installed.
