Re: ESP32 freezed : "wifi: TX Q not empty"

hi pranava,

Re: Guru Meditation Error: Cache disabled but cached memory region accessed

actually after migrating to esp-idf 3.2 i felt with this issue only ones in a while. the similar code with esp-idf 3.1 i did't met with this issue. sorry that i can not able to send you the code, that is belongs to my employer. are the coredump file and .elf file useful to find the issue?
