My question is: what do you expect the user to do in this case? Seeing how it's not self repairing or anything, you just brick your device with this.

[Mttrinh]

Hi, 

We haven't been able to reproduce this assert even after rebooting the device several thousand times. Looks like the cause of this assertion is possibly corrupted length field of the written entry. Such corruption can occur if the flash power supply is unstable, and if flash data gets corrupted such assertion can trigger.

Seems like the problem occurred for the page starting at 0x6D000 (since p_end is 0x6E000 as per the debug logs) and a flash dump for that page haven't been provided. Could you provide a full flash dump when this issue happens and also ensure that the chip power supply is stable?

[bart]

So by the time you asked for this full dump, I already decided disable persistent storage, and thus couldn't provide you with a full flash dump. However, we started using it again, and again ran into mesh asserts after some time.

I suspect it started on brownout (already have a couple cases that are crashing since we enabled mesh persistent storage), which happens when the device is unplugged.

This time it crashes at some other place in the code, but again during loading from flash at init.
