rst: no_mean

yes, this question is simple and strange, but what can cause "no_mean reset"? Its just my curiosity... :D

Yes wear leveling helps and you only erase when you run out of space not on every write
How many writes one simple nvs partition (4KB) with default wear leveling (4K) can do approximately? I need numbers and how to math this?!

[4K*4K*100K(flash write cycle)]/data_write_size(1B) = 1.6M writes ??

Task wdt has weak handler and yes, you can do this. esp...
