ESP 32 Keep rebooting/resetting

Postby Cbuustos » Wed Jun 12, 2024 11:39 am

Previously, my LOLIN ESP32-S3 works properly, However, after updating Arduino and my MAC this error started spawning.
Despite using an Arduino board and the code work, when I upload the same code in a ESP 32 it don't work. So I am starting to think that it could be a problem with the uploading configuration.
- There is no problem with my USB
- I don't think there is a problem with alimentation de board


Brownout detector was triggered

Firstly, try Blink example if it works. After that, minimize your code to check where the problem is. Post your code if possible.

I can add to this that Brownout suggests that the ESP's supply voltage is dropping below some predefined threshold. This could be caused by a number of things, among them the power supply being insufficient, the ESP drawing too much current (likely too much load on the pins), or some big transients on the power rail combined with too long of a cable between the supply and the circuit.

How are you powering your system? And when you say you updated your Arduino does this mean that you changed your code? Could it be that you added additional IO pins?
