Thank you for such a clear walkthrough!
Followed this process and it worked perfectly with HassOS 5.2.
Only difference was that after eeprom update the bootloader version was dated 3rd September not 16 July - so maybe there is an updated version?
I restored everything from RasPi3B snapshot (other than 0.114 OS).
It has only been a couple of hours but all add-ins are currently working without any issues:
- UniFi controller
- deconz (with Conbee II on an extension lead - all sensors and lights working)
- Mosquitto broker (all entities showing as available)
- File editor (and also Notepad++ with SSH)
- Samba share
- Home assistant Google Drive Back up
- RasPi4 4gb
- Crucial BX500
- Simplecom SE221 Enclosure
This SSD and enclosure also previously worked on my RasPi3B.
If it is of any use to someone, the following custom cards also working without issue (all were previously installed manually on RasPi3b, and restored from snapshot - I did try to link but as a new user I couldn’t have more than 2 links):
And these integrations in addition to those mentioned above:
- Daikin AC
- Google Cast
- Logitech Harmony hub
- TP-Link Kasa Smart
Hope the above is useful for someone.
Once again, thanks to the community for all the help and assistance in making this work.
