I was debugging one device that I designed for a whole day because it kept crashing in AP mode with random crash dumps, sometimes without any dump, just watchdog reset. First I thought it was the sketch but it worked on a different device. And it turns out, the issue was 10k pullup on EN pin. When I replaced it with a 0ohm resistor, it works.
I was under impression 10k is well enough for the EN pin and the datasheet also just mentions to pull it high. NodeMCU for example uses 12k pullup (it uses ESP-12 module though) in the schematic so maybe it's just ESP8285 specific issue. I stand corrected and maybe this helps someone.
