Important Notes for Portenta_H7

The LittleFS of the new Portenta_H7 board currently tested OK with only maximum 8 files. The files, from 9 and up, somehow strangely can't be written and / or read. This is possibly a bug in the ArduinoCore-mbed mbed_portenta core. The same behaviour is observed from core v2.0.0 up to v2.6.1.

If LittleFS size is reduced to 1024KB, test is OK with only maximum 4 files.

Beware and keep checking for updates.

Why do we need this MultiResetDetector_Generic library

Features

MultiResetDetector_Generic is a library for the Arduino AVR, Teensy, SAM DUE, SAMD21, SAMD51, STM32F/L/H/G/WB/MP1, nRF52, RASPBERRY_PI_PICO, RTL8720DN, Nano_33_BLE, Portenta_H7, etc. boards to detects a multi reset, within configurable timeout (default 10s) seconds, so that an alternative start-up mode can be used. Example use cases are to allow re-configuration of a device's WiFi / MQTT / Blynk credentials or to count the number of resets within a pre-determined timed.

The RP2040-based boards, such as Nano RP2040 Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040, are currently supported using Earle Philhower's arduino-pico core or Arduino mbed OS for RP2040/Nano boards.

This library is based on, modified, bug-fixed and improved from

1. Stephen Denne's DoubleResetDetector
2. Khoi Hoang's ESP_DoubleResetDetector
3. Khoi Hoang's ESP_MultiResetDetector
4. Khoi Hoang's DoubleResetDetector_Generic

to add support for AVR, Teensy, SAM DUE, SAMD, STM32, nRF52, RTL8720DN, RP2040-based boards, Nano_33_BLE, Portenta_H7, etc.

Currently, DoubleResetDetector only supports ESP8266 using RTC memory, ESP_DoubleResetDetector and ESP_MultiResetDetector only ESP8266 and ESP32, DoubleResetDetector_Generic only for double reset detection.

This library can be used to detect a multi reset within a predetermined time to force the program to enter a special operation such as Config Portal, Clear Default Data, etc., using :

1. EEPROM for AVR, Teensy boards.
2. FlashStorage_SAMD library for SAMD21 and SAMD51 boards (ZERO, MKR, NANO_33_IOT, M0, M0 Pro, AdaFruit Itsy-Bitsy M4, etc.)
3. FlashStorage_STM32F1 library for STM32F1 and STM32F3 boards
4. FlashStorage_STM32 library for STM32F/L/H/G/WB/MP1 boards
5. DueFlashStorage library for SAM DUE
6. Adafruit's LittleFS/InternalFS for nRF52
7. LittleFS for RP2040-based boards, such as RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040 using Earle Philhower's arduino-pico core
8. LittleFS for RP2040-based boards, such as Nano RP2040 Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040 using Arduino mbed OS for RP2040/Nano boards.
9. FlashStorage_RTL8720 library for Realtek RTL8720DN, RTL8722DM, RTL8722CSM, etc.
10. LittleFS for MBED nRF52840-based boards, such as Nano_33_BLE, Nano_33_BLE_Sense using Arduino mbed OS for Nano boards.
11. LittleFS for Portenta_H7 boards, using Arduino mbed_portenta core for Portenta boards.

• ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.
• ~/.arduino15/packages/STM32/hardware/stm32/2.3.0/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h for Nucleo-64 NUCLEO_L053R8.

Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz, these files must be copied into the corresponding directory:

• ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32F7xx/F765Z(G-I)T_F767Z(G-I)T_F777ZIT/NUCLEO_F767ZI/variant.h
• ~/.arduino15/packages/STM32/hardware/stm32/x.yy.zz/variants/STM32L0xx/L052R(6-8)T_L053R(6-8)T_L063R8T/NUCLEO_L053R8/variant.h

Purpose

Detects a multi-reset so that an alternative start-up mode can be used. One example use is to allow re-configuration of a device's WiFi or Blynk Credentials or to count the number of resets within a pre-determined timed.

How It Works

When the device starts up it checks the EEPROM, (Due)FlashStorage or LittleFS file /mrd.dat for a flag to see if it has been recently reset within the configurable timeout seconds
