RTCWDT_RTC_RESET issue

[nicosandller]

Hi!

I'm using a new Tiny PICO usb C board and after flashing in the example sketch:

#include <TinyPICO.h>

// Interval between internal temperature reads
unsigned long next_temp_read = 0;   // Next time step in milliseconds
uint8_t temp_read_interval = 1000;  // This is in milliseconds

// Initialise the TinyPICO library
TinyPICO tp = TinyPICO();

void setup()
{
    // Not used
}

void loop()
{
    // Cycle the DotStar colour every 25 milliseconds
    tp.DotStar_CycleColor(25);

    // You can set the DotStar colour directly using r,g,b values
    // tp.DotStar_SetPixelColor( 255, 128, 0 );

    // You can set the DotStar colour directly using a uint32_t value
    // tp.DotStar_SetPixelColor( 0xFFC900 );

    // You can clear the DotStar too
    // tp.DotStar_Clear();

    // To power down the DotStar for deep sleep you call this
    // tp.DotStar_SetPower( false );

}

I'm also using PlatformIO so this is my platformio.ini:

I'm getting the following error:

I thought it was browning out but I already ruled out power supply issues (plugged in a battery, a reliable cable and even directly from a bench power supply).

All my pins are disconnected to sensors etc.

The initial program (that cycles the neo pixel) was running correctly before flashing the new program.

Any ideas on what might be going on?

Thanks!

Set the flash mode to DIO not QIO.

Thanks! That was the issue.

for future reference, this platformio.ini fixed it:

[env:esp32]
board_build.flash_mode = dio
platform = espressif32
board = tinypico
framework = arduino
monitor_speed = 115200
build_flags = 
    '-DVERSION="0.0.1"'
    -D DEBUG=1
lib_deps = tinypico/TinyPICO Helper Library@^1.4.0
