v5.1.0 broked something related to LittleFS and SPIFFS with TinyPICO board... works in Arduino IDE.

This is a small code sample that read and write to Little FS on ESP32.

#include "WiFi.h"
#include <FS.h>
#include <LittleFS.h>

void setup() {
  Serial.begin(115200);
  // Set WiFi to station mode and disconnect from an AP if it was previously connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);
  Serial.println("Setup done");
  if (!LittleFS.begin(true)) {
    Serial.println("Formatted");
  } else {
    Serial.println("Formatteddd");
    LittleFS.format();
  }
  File file = LittleFS.open("/prova.txt", "w");
  //Write to the file
  file.print("dsadasdsa");
  delay(1);
  //Close the file
  file.close();
  Serial.println("wrote");
  File file2 = LittleFS.open("/prova.txt", "r");
  if (!file2) {
    Serial.println("No Saved Data!");
  }
  Serial.println(file2.read());
}

void loop() {
  Serial.println("scan start");

  // WiFi.scanNetworks will return the number of networks found
  int n = WiFi.scanNetworks();
  Serial.println("scan done");
  if (n == 0) {
    Serial.println("no networks found");
  } else {
    Serial.print(n);
    Serial.println(" networks found");
    for (int i = 0; i < n; ++i) {
      // Print SSID and RSSI for each network found
      Serial.print(i + 1);
      Serial.print(": ");
      Serial.print(WiFi.SSID(i));
      Serial.print(" (");
      Serial.print(WiFi.RSSI(i));
      Serial.print(")");
      Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN) ? " " : "*");
      delay(10);
    }
  }
  Serial.println("");

  // Wait a bit before scanning again
  delay(5000);
}

if I use a TinyPICO board, this small snippet fails reading writing LittleFS when using espressif32@5.1.0 it works well when using espressif32@5.0.0

I noticed that the only way to make it work with espressif32@5.1.0 is to use board_build.flash_mode = qio instead of board_build.flash_mode = dio

but this does not have sense to me.

when using espressif32@5.0.0 that snippet works with both QIO and DIO.

the problem happen on TinyPICO board only, it does not happen on LolinD32 or other ESP32 boards I have.

Same snipped always works well with Arduino IDE when using Core 2.0.4.

@valeros Perfect! Thx, for your great support 😃

@cyberman54 Just run pio platform update espressif32 in the IDE terminal.
