Need Help with DualOptiboot Fota

SuperNinja · 1 Feb 2021, 20:33

Hi everyone,
I just discovered MyController, following the use of MySensors 2.3.2 and I see that there is a lot of potential compared to MYScontroller: bravo to the whole team!

What works: My Nodes and Gateway (serial) work and are recognized in MYController.
The (minimum) equipment to test FOTA: I have a 328p Bare Bone (8MHz internal) + SPI Flash memory + 3.3v regulator + RFM69HCW.
What I would like to do: if I understood correctly: just burn the DualOptiboot bootloader WITHOUT SKETCH. The first time it is turned on, it will ask MYController for an identifier and I could load the sketch from MYController OTA: Actions >> Upload firmware.

It's just ?

For that, I need the DualOptiboot.hex which corresponds to my Node (8MHz internal, BOD 2.7v ...) which I must flash in my 328P with AVRDUDESS.

Someone to help me find this bootloader.

@superninja Welcome to MyController
I usually go with Sensebender bootloader.
Steps :

setup Arduino IDE for Sensebender - https://github.com/mysensors/ArduinoBoards
Select your hardware details. from your input, the board: sensbender, 328 + 8 Mhz
Burn bootloader from IDE (it should be DualOptiboot)
add a sketch with #define MY_OTA_FIRMWARE_FEATURE - https://github.com/mysensors/MySensors/blob/2.3.2/MyConfig.h#L1222~L1253

Afterburn DualOptiboot, you should add a MySensors sketch via serial (OTA feature should be enabled on your sketch). From this point, OTA works with DualOptiboot

@jkandasa Thanks for this fast and clear response , i'll test this and come back here .

@jkandasa this is what i do :

I loaded the ArduinoISP sketch on an Arduino PRO mini to use as a programmer.
then I configured Arduino IDE with the SensBender 8MHz board like this:

and I started the bootloader burning which went well.
I unplugged the ProMini and plugged in an FTDI converter to program the ATMega 328P by configuring like this:

I injected this simple BLINK LED sketch :

    ledState = !ledState; // Inverse l'état de la LED
    digitalWrite(LED_BUILTIN, ledState); Serial.print("LED  "); Serial.println(ledState);
  }

}// FIN de LOOP

the led is flashing well and MYController sees the node
I change the flashing delay from 1000 to 500 and the version which goes from 1.0 to 1.1. I compile the sketch which gives me: moteino_MySensors_fota_pr1.ino.hex
I go to Utilities>>Firmware and add a Type, Version 1.1 and Firmware (with faster flashing delay)
I go back to Resources>>nodes and upload the firmware of this node n°4
and ...nothing after 7 minutes

Any Idea ? My Sketch is wrong ?

@superninja you can see some staus on the node page. also on the Status >> Resource logs, you can see some messages. Enable Settings >> System >> MyController >> Resources logs level to notice or debug.

also try #define MY_OTA_FLASH_JDECID 0x00, which works for me.

@jkandasa Thank you for your help: I summarize what you asked me to do and which works now:
The (minimum) equipment to test FOTA: I have a ATMega 328p BareBones (8MHz internal) + led attached to PB1 (pin15)+ SPI Flash memory + 3.3v regulator + RFM69HCW.

Install ArduinoISP program to ProMini (Programmer)
Connect MySensors board on ProMini (ArduinoISP) via ISP header
Select, Programmer="Arduino as ISP", Board:"Sensbender Micro", Processor:"Atmega 328 8Mhz"
Now click on "Burn Bootloader". bootloader will be loaded on MySensors board
Remove ISP header and remove ProMini from your computer
Connect MySensors board to USB via FTDI connector
Upload MySensors sketch(OTA should be enabled on the sketch) to MySensors board
Now the MySensors node will appear in MyController server.
Modify the MySensors sketch and upload it to MyController
Now trigger "Firmware upload" from MyController server page.

This is the first sketch to upload one time with the USB to FTDI connector :

//pr1: minimal sketch for fota with blink led


#define blinkTime 200  
#define SKETCH_NAME "SensBender Led 200 -70"  //25 caracteres max

#include <MySensors.h>

//===================================
//=              SETUP              =
//===================================
void setup() {//pas besoin de Serial.begin(115200)
  pinMode(LED_BUILTIN, OUTPUT);
  Serial.print("Start "); Serial.print(SKETCH_NAME); Serial.print(" "); Serial.println(SKETCH_VERSION);
}//FIN du SETUP
//==========================================
//=              PRESENTATION              =
//==========================================
void presentation() {
  // Send the sketch version information to the gateway and controller
  sendSketchInfo(SKETCH_NAME, SKETCH_VERSION);
} // FIN de PRESENTATION
//===================================
//=              LOOP               =
//===================================
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  Serial.print("LED ON ");
  wait(blinkTime);
  digitalWrite(LED_BUILTIN, LOW);  Serial.println("LED OFF ");
  wait(blinkTime);
}// FIN de LOOP

Change blinkTime time and compil the sketch , then upload firmware .hex with MYCONTROLLER.
Enjoy
