Brownout detector was triggered - cannot revert to working state

[eduardoro]

Hi,

I am using an ESP32 board with a code running properly. Nothing was attached to the board

I plugged a TFT screen on the board, uploaded my code to use the screen, and started getting this error below.

I understand it is related to a lack of power and I saw several suggestions for addressing it.

I removed the screen and reverted the code to what worked before, but the error doesn’t go away. Still nothing connected to the board

I am not even sure the code is being updated or executed.

I am now trying with a very basic code just to print some on the Serial.

I also tried:

Code: Select all

#include "soc/soc.h"
#include "soc/rtc_cntl_reg.h"

void setup()
{
  WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0);
  
  Serial.begin(115200);
  Serial.println("Brownout detector disabled");
}

void loop()
{}

and with
#define CONFIG_ESP_BROWNOUT_DET 0

The error remains

Is there a way to force get it back to work?

Kind regards

Code: Select all
