ask for help!my ESP-WROOM-32 Constantly restart like this,what should i do?
After erasing the flash, re-flash the firmware, it is useless, or the code that appears above. Hope your help, thanks!

Hi yulihui404,

The log is too generic to guess what the issue might be.
It may either h/w of s/w issue depending on your h/w and s/w configuration.

To help with troubleshooting you need to provide some details:
1. What is your development platform (Arduino, ESP-IDF, PlatformIO, other) and at what release?
2. Do you experience this issue running standard example blink.c / blink.ino and using default settings?
3. If blink.c / blink.ino works correctly and this issue is with your custom code, then what is the code?
4. Do you use a bare ESP-WROOM-32 module or some development board with ESP-WROOM-32? Which board? What is the wiring if you are using a bare module?

Do the esp-idf examples run?
You can also find hints to which line is crashing your code by using "make monitor" or manually resolving the address using addr2line.

idk why but read the docs seems to be offline. This would be the link...
