[Application Failure - Bad Code] esp32c3 always rebooting

[frrhhhann]

Board

esp32c3

Device Description

i recently made digital dash for display car ecu data using xiao seed esp32c3, but the esp32 keep rebooting, the code i'm using is from this github https://github.com/73Volvo/Speedypal/tree/main but the original code is for xiao seed esp32s3 with 0.96 oled ssd1306, i custom the code for using xiao esp32c3 only delete led indicator because xiao esp32c3 don't have built in led, and change ssd1306 library to sh1106g. it works fine it can upload the code and display startup logo but it keep rebooting

Hardware Configuration

xiaoo esp32c3, D4 D5 for i2c connect to sh1106g 1.3 inch oled, D7 D6 for RX TX comunication to ecu

Version

latest master (checkout manually)

IDE Name

arduino ide

Operating System

windows 10

Flash frequency

160Mhz

PSRAM enabled

yes

Upload speed

115200

Description

i finished project but my xiao esp32c3 keep rebooting in serial monitor

@frrhhhann - what are those pins:

// constants for arduino pins
const int8_t ButtonPinL = D1;  // the number of the left button pin
const int8_t ButtonPinR = D2;  // the number of the right button pin
const int8_t chipSelect = D3; // D3 for Seeed ESP32S3, 21 for Seeed Sense  // the number of Chip Select pin for the SD card
const int8_t TXpin = D6;  // the number of the TX pin
const int8_t RXpin = D7;  // the number of the RX pin

Those are not listed in https://github.com/espressif/arduino-esp32/blob/master/variants/esp32c3/pins_arduino.h

i change the pin but still have rebooting problem

[SuGlider]

My suggestion is to run this sketch using Core Debug Level: "Verbose".
Add this line to the code:

void setup()
{
  pinMode(ButtonPinR, INPUT_PULLUP);
  pinMode(ButtonPinL, INPUT_PULLUP);

  Wire.begin();
  Serial.begin(115200); // usb connection on Arduino Nano
  Serial.setDebugOutput(true);  // <=== this line will force all Debug Output to go to USB CDC port

i add this to the code but still no luck

Serial.setDebugOutput(true);  // <=== this line will force all Debug Output to go to USB CDC port

Did you set the core debug level to Verbose in the board menu?

20:47:40.604 -> Guru Meditation Error: Core 0 panic'ed (Load access fault). Exception was unhandled.

@frrhhhann - this is a memory fault error. Bad pointer.

I have found it... in splashStart().
frame value goes beyond the Speeduino_Logo_Anim_Array[frame] array boundary.

Fix it by if (frame >= \* ">" only is the bug *\ Speeduino_Logo_Anim_LEN) frame = 0;

[SuGlider]

No Arduino Core issue. This is user code failure.

where do i need to replace the code?
