Flash Read Failed - OTA Update

[malyjak]

Board

ESP 32 Dev Module

Device Description

DevKitC on plain breadboard

Hardware Configuration

None

Version

v2.0.7

IDE Name

Arduino IDE

Operating System

Windows 11

Flash frequency

80MHz

PSRAM enabled

no

Upload speed

921600

Description

After calling

Update.begin(UPDATE_SIZE_UNKNOWN, cmd)

from Update library, where cmd is:

cmd = (filename == "filesystem") ? U_SPIFFS : U_FLASH;

in case of U_FLASH an error is produced in serial monitor:

Flash Read Failed

and the update process is terminated.

In case of U_SPIFFS , everything goes well.

Sketch

void handleUpload(AsyncWebServerRequest *request, String filename, size_t index, uint8_t *data, size_t len, bool final)
{
  if (!index)
  {
    int cmd = (filename == "filesystem") ? U_SPIFFS : U_FLASH;
    if (!Update.begin(UPDATE_SIZE_UNKNOWN, cmd))
    {
      Update.printError(Serial);
      return request->send(400, "text/plain", "OTA could not begin");
    }
  }

  // Flash the new firmware.
  if (len)
  {
    if (Update.write(data, len) != len) {
      return request->send(400, "text/plain", "OTA could not write");
    }
  }

  if (final)
  {
    if (Update.end(true))
    {
      Serial.println("Update successful!");
      Serial.println("Rebooting...");
    }
    else
    {
      Update.printError(Serial);
    }
  }
} // End: handleUpload()

Debug Message

Flash Read Failed

Other Steps to Reproduce

I'm using https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json in Arduino IDE 1.8.19 to get this BSP. The reason for 1.8.19 is that I need https://github.com/me-no-dev/arduino-esp32fs-plugin to save web server data on the file system and 2.x seems not to support external tools.

I have checked existing issues, online documentation and the Troubleshooting Guide

It seems to be a partition error.

You might be right. However, I checked the first partition scheme from the Arduino IDE menu with gen_esp32part and it is actually quite similar to the “Factory app, two OTA definitions” configuration

Creates this:

Which is similar to:

The partition table starts at 0x8000 instead of 0x9000 for my esp32.

Board
ESP32-C3

Version
v2.0.7

IDE Name
VS Code (PlatformIO plugin)

I have the same problem

And this is my partition

[asushugo]

I replaced the v2.0.6, and it works

[malyjak]

v2.0.6 doesn't work for me in Arduino. I'll try VS Code as well. @SuGlider can you please set a proper label since this is clearly a bug not a question? Thanks!

I replaced the v2.0.6, and it works

@asushugo can you please share your platformio.ini? I tried:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
platform_packages =
	platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.6
monitor_speed = 115200
board_build.partitions = partitions.csv
lib_deps = 
	me-no-dev/ESP Async WebServer@^1.2.3
	arduino-libraries/LiquidCrystal@^1.0.7
	adafruit/Adafruit Unified Sensor@^1.1.9
	adafruit/DHT sensor library@^1.4.4

And I still haven't succeeded in making this error go away.

I set the partitions.csv to be identical with the one generated by the Arduino IDE:

# Name,   Type, SubType, Offset,   Size
# Note: if you have increased the bootloader size, make sure to update the offsets to avoid overlap
