ESP32-CAM rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) fault

[halitekmekcioglu]

Hardware:

Board: ESP32-CAM WROVER MODULE Core Installation/update date: 11/jul/2017 IDE name: ARDUINO 1.8.9 Flash Frequency: 80 MHZ PSRAM enabled: no Upload Speed: 115200 Computer OS: Windows 10

Description:

I've got newly ESP-32CAM and I programmed it in the office for basically start it, everything was worked properly. Then I came home, and I want to connect it to home wifi, I set up everything for my laptop and I installed same program. Only one thing I know happened, I've connected +5v to directly its 5V pin and board had started to be warm, I realized it and I changed it to 3.3V. After that, I started to get this script on serial monitor.

Sketch:

include "esp_camera.h"

include

include "soc/soc.h" //disable brownour problems

include "soc/rtc_cntl_reg.h" //disable brownour problems

// // or another board which has PSRAM enabled //

// Select camera model //#define CAMERA_MODEL_WROVER_KIT //#define CAMERA_MODEL_ESP_EYE //#define CAMERA_MODEL_M5STACK_PSRAM //#define CAMERA_MODEL_M5STACK_WIDE

if defined(CAMERA_MODEL_ESP_EYE)

pinMode(13, INPUT_PULLUP); pinMode(14, INPUT_PULLUP);

endif

// camera init esp_err_t err = esp_camera_init(&config); if (err != ESP_OK) { Serial.printf("Camera init failed with error 0x%x", err); return; }

sensor_t * s = esp_camera_sensor_get(); //initial sensors are flipped vertically and colors are a bit saturated if (s->id.PID == OV3660_PID) { s->set_vflip(s, 1);//flip it back s->set_brightness(s, 1);//up the blightness just a bit s->set_saturation(s, -2);//lower the saturation } //drop down frame size for higher initial frame rate s->set_framesize(s, FRAMESIZE_QVGA);

if defined(CAMERA_MODEL_M5STACK_WIDE)

s->set_vflip(s, 1); s->set_hmirror(s, 1);

endif

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected");

startCameraServer();

Serial.print("Camera Ready! Use 'http://"); Serial.print(WiFi.localIP()); Serial.println("' to connect"); }

Originally, properly working code is above, nothing much changed though. Only SSID and SSID PASSWORD changed.

This, I started to get it from the serial monitor:

Any ideas, advice? Thanks for advance.

Hi mr. HALIT,

I have the same problem with you.

I use ESP32 Dev KIT, and have a SW_RESET problem on the device.

maybe you need to update the ESP SDK or esptool on the arduino IDE.

see https://github.com/espressif/arduino-esp32/issues/3461

[halitekmekcioglu]

Thanks, problem solved. This link helpful for this issue. https://randomnerdtutorials.com/esp32-troubleshooting-guide/

[Tcoton]

I have found that one of my ESP32 modules had this exact issue, setting the flash frequency to 40MHz instead of 80MHz solved the issue, no more reboots.

[Cyril995]

@Tcoton how do you change 80Mhz to 40Mhz ? any guidance ?

[Tcoton]

Using Arduino IDE, select the ESP32 Dev Module as a board and a bit below, you will find the Flash Frequency set to 80 MHz by default, set it to 40 MHz and check other settings too. I personally use the following settings on the weirdo ESP32-CAM I have:

Board: ESP32 Dev Module Upload Speed : 921600 (default) CPU Frequency: 240MHz (default) Flash Frequency: 40 MHz Flash Mode: QIO (default) Flash size: 4MB (default) Partition Scheme: Huge APP (3MB No OTA/1MB SPIFFS) Core Debug Level: None PSRAM: Enabled

Again, this is specific to my weirdo board and it took me ages to figure why on earth it would not work with any other settings than the Flash Frequency set to 40 MHz, flashing with the AI-Thinker board which offers no settings was making the board to loop reset. The second module I have bought at the very same time at the vey same place did not have this issue at all.

thank you very much

[meakdemir]

Means it is a HW problem folks, first check your USB to ESP32 cable, try with another one. Using another cable fixed my problem. FYI.

[TENGYIHONG]

我的ESP32 -cam也出现这样的问题，自己换过flash。上面的方法试过，都无法解决问题。

I solved this question by connecting the board also to the 5v power instead of using 3.3v only. I guess 3.3v cannot provide enough power supplement for ESP32.

I had the same error, I checked the esp32 board was the most updated. is there any other solution?

Thanks, problem solved. This link helpful for this issue. https://randomnerdtutorials.com/esp32-troubleshooting-guide/

how? i'm still confused

[Tsurematsu]

If the error is of any use to me because the cable I used did not provide enough voltage to the microcontroller. 3 to 5 volts
