The "Machine:" lines do not match what model is present in the .dtb
files.
Does /proc/device-tree/model show exactly what you have in the
"Machine:" lines?
Yes, /proc/device-tree/model shows exactly what I mentioned in the "Machine:" lines:
“Raspberry Pi 5 Model B Rev 1.0” and “Raspberry Pi 3 Model A Plus Rev 1.1”
To clarify, I’ve tested only on the following specific revision of boards:
Raspberry Pi 5 ( Revision 1.0)
Raspberry Pi 3 A+ (Revision 1.1)
It seems there are other revisions of these models. The reference for those is the Raspberry Pi revision code list:
