@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

Hi
I am using Omega 2s and see this error "jffs2: Node CRC d88f4121 != calculated CRC 764b7307 for node at 0045bed0 cat: read error: I/O error"

I have been over the layout and seen that all pins are connected as recommended, but despite of that I still see this failure. I am not able to figure out what causes this and will appreciate all hints and ideas to debug this further.

Thanks in advance
