hello,
I am working on a board that contains the esp8685h4 chip. i use the ESP's internal 4Mbyte NOR flash for burning code and saving data during run.
when i run my program, it can be functioning properly for many hours ...

to clarify, this problem occurs randomly during runtime? and once you reset the esp it boots normally as expected? like, the problem disappears?

can you say what exactly the code does, and approximately what happens just before the esp goes into this state?

this problem only occurred because of the encryption? it didn't happen before?

did the invalid header error happen immediately after trying to program the esp or after some time the esp has been working?
