@magge Thanks for sharing your detailed testing report. I agree with @crispyoz's suggestion to try running your software on stock Onion hardware - this way we can rule out circuit issues. @magge said in Omega2S+ overlay JFFS2 filesystem corruption: Is there a prototyping board I should order when working with this? I tried to google for it but did not get any wiser... There's an Omega2S development board you can use. Or if you would prefer, you can use an Omega2+ and an Expansion Dock. Our distributors have all 3 products in stock and ready to ship.

Posting an update on this topic received on our helpdesk: After a lot of investigation, we already identify and solve the problem. The problem was on a cable inside our Gateway that induces electromagnetic signals on the Onion Omega 2+ when the GPRS is in use. We already protect the Onion Omega 2+ from electromagnetic signals and right now we are confident that it is solved.

I was searching for a similar data, had a go at doing likewise yet it didn't worked!

@Ryan-Pedersen The error does occur after random time and it happens for a bare system solely installing the Linux system installed on the Onion-2s module. I have tested this for several modules and seems to be systemic for my boards. It looks like the jffs2 is corrupted during kernel idle . There is no power interruption but despite of that, the operation fails. Again, all inputs to debug this further is very welcome. Thanks in advance

First step in debugging would probably be to explore what was ending up in the overlay. One likely culprit is upgrading large amounts of system software (python, etc) or installing many new packages. The other is having some ongoing task that creates log files or data objects
