About eth2wifi transmit error

[OOOOOOOPF]

I made my own board with esp-wroom-32UE, and a SR8201F ethernet chip, when I test eth2sta code, everything goes well, and then for about 1 mins or 5mins later, the ethernet suddenly can't send message to PC, and the chip begin to reboot in different reason, below are my logs, I want to know why:

[ESP_ondrej]

I noticed several occasions of "Brownout detector was triggered" in your log. It indicates some issues with HW, more specifically this message is reported when voltage supplied to the chip gets too low.

See for example https://randomnerdtutorials.com/esp32-t ... ing-guide/ bullet 8) for some hints how to fix.
