Hi António,
Any further news or theories on the wear you are seeing?
We too are experiencing wear issues with the M62704 (BBG) and W62704 (BBB Industrial).
These are the majority of our 74 boards (see attached spreadsheet). A couple of the BBG have MK2704. These boards started going into the field since mid 2024.
Even though some boards are showing end of life (according to wear) the boards are operating normally, but we do not know how long this will last.
Occasionally a board will become either corrupt or only allow the flash to mount read only. Both require a board change. Returned boards show eMMC wear. All the boards are running Linux 6.1.20.
Given @RobertCNelson has created a separate thread here, I assume this is a different issue to the MK2704 above.
We only notice the wear metrics changes after a power cycle of the board.
Sometimes our application looks like a contributor (large db log index), but often this is not the case. We have yet to be able to reproduce wear increases without doing excessive db writing. This is not the case for many of our boards in the field.
The uptime of the boards can be very long.
Do you think the uptime is a contributing factor? Would rebooting each day help reduce wear?
Look forward to any probing questions or theories.
Thanks,
David
