M5StickC Plus2 not booting

  • HI all,

    I'm really new to all this so probably done something wrong myself so looking for some help.

    After flashing some code from platformIO within VSCode that i knew worked before my unit has gone dead.. It seems to successfully receive code from PlatformIO and from M5Burner which i've tried to re-upload the factory test firmware.

    If i hold the power button for 6 seconds the internal green LED stays on whilst i'm holding the button but the screen doesn't come on at all.

    When i connect to the serial monitor from M5Burner and reboot the Stick this is what i get

    rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
    configsip: 271414342, SPIWP:0xee
    mode:DIO, clock div:1
    entry 0x400806ac
    M5StickCPlus initializing...OK
    find 34 addr faild

    Does anyone know if its recoverable or if its now dead?

    Thanks in advance.

  • @psymonbee ESP32s have a secure BootLoader burnt into ROM and is un-brickable!
    Your unit is crashing on boot, which happens when the user program is faulty. It may be as simple as a test program with no delay, jamming up the CPU, or a program that uses all the memory of makes calls out of bounds.
    The Bosch BNO085 that I have temporarily crashed all my ESP32s, which took an hour each to clear up! It is now in 'quarantine' \o/
    I use Arduino IDE because it is easy. Period. Full stop.
    I can see if it is connected or flickering in and out of connection.
    Use 'erase all flash before uploading' and upload a simple test like this.

    bool ticktock;  //declare ticktock as a boolean flag
    void setup() {           //runs once on start up
      Serial.begin(115200);  //open the serial port for USB cable
    void loop() {            //runs in circles!
      ticktock = !ticktock;  //every pass through reverse the flag
      if (ticktock) {        //test current value of the ticktock flag
      } else {  //prints one or the other to the USB port
      delay(1000);  //wait for a second and run again!

    --With no other libraries. There will be no video!--
    Get this working and build up from there.
    -Good Luck!

  • I’m not sure if the situation is the same? The following is for reference

  • can you do ERASE from M5Burner?
    Can you load any basic Arduino code for M5StickCPlus2 from examples?
    When you do M5Burner firmware is it for Plus2 stickC - check if by chance it is not Plus version or StickC.
