ESP32: flash del firmware binario compilato (.bin) – 1

Spread the love

Come per esp8266, una caratteristica importante dell’ESP32 che semplifica la condivisione del firmware (ed è utilizzata dalla maggior parte dei produttori) è quella di generare un file binario precompilato con solo la parte sketch (o filesystem).

ESP32: compiled binary (.hex) with command line

Puoi compilare il codice sorgente per il tuo dispositivo, ma puoi anche generare un file binario per il filesystem.

Qui alcuni dispositivi esp32 comuni che utilizzo ESP32 Dev Kit v1 - Selectable - TTGO T-Display 1.14 ESP32 - NodeMCU V3 V2 ESP8266 Lolin32 - NodeMCU ESP-32S - WeMos Lolin32 CP2104 CH340 - ESP32-CAM programmer - ESP32-CAM bundle - ESP32-WROOM-32 - ESP32-S

Aggiungi output dettagliato all’IDE di Arduino

Per comprendere meglio tutti i processi, abiliteremo l’output dettagliato sul nostro IDE di Arduino. Puoi trovare queste opzioni su File -> Preferences e controllare i controlli Show verbose output.

Arduino IDE enable show verbose ouput

Ora possiamo prendere e riutilizzare il comando dalla console.

Generare il file binario per l’ESP32

Esamineremo l’output della console del nostro IDE Arduino e proveremo a capire il processo di compilazione e caricamento.

esptool

Per prima cosa osserviamo che il componente principale del core ESP32 necessita dell’installazione di python e durante l’installazione ricorda di aggiungerlo alla path base (per Windows)

ESP Tools Install Python and add It to path
ESP Tools Install Python and add It to path

Il comando utilizza l’esptool dell’IDE Arduino interno, ma è possibile installare solo esptool.py per Python con un semplice comando

pip install esptool

oppure puoi scaricare da qui la versione compilata, ricordati di aggiungere l’eseguibile alla path.

Quindi se avvii esptool sul tuo cmd, hai queste informazioni

Parametri della riga di comando

Ora possiamo capire meglio i parametri del comando:

  • --chip esp32: qui selezioneremo il chip corretto;
  • --port COM26: impostiamo la porta;
  • --baud 921600: qui abbiamo la velocità di trasferimento;
  • --before default_reset: operazione di pre-caricamento;
  • --after hard_reset: operazione post-caricamento;
  • --flash_mode dio: imposta la modalità flash;
  • --flash_freq 80m: frequenze flash fino a 80Mhz;
  • --flash_size detect: rileva automaticamente la dimensione del flash;
  • write_flash: scrive un blob binario su flash;
  • <address> <binary file>: scrivere per assegnare un indirizzo al file.

Comprendere i file binari

Come possiamo vedere, ci sono molti file binari e devi caricarli tutti per avere un sistema coerente:

0xe000 <tools>/partitions/boot_app0.bin

Bootloader di prima fase: il bootloader ROM hardwired viene eseguito per primo. Questo bootloader di primo stadio è al di fuori della memoria Flash e non può essere programmato. Carica il bootloader di seconda fase (vedi il passaggio successivo).

0x1000 <tools> /sdk/bin/bootloader_dio_80m.bin

Bootloader di seconda fase: il bootloader della ROM di prima fase carica il bootloader del software ESP-IDF di seconda fase all’indirizzo 0x1000 in Flash. Il codice qui è l’eseguibile bootloader_dio_80m.bin, che può essere trovato nella directory components/bootloader del framework ESP-IDF. Questo bootloader di seconda fase legge la tabella delle partizioni trovata per impostazione predefinita all’offset 0x8000. Se nella tabella delle partizioni vengono trovate partizioni dell’app OTA, il bootloader consulta la partizione ota_data per determinare quale deve essere avviata.

0x8000 <sketch>/Blink.ino.partitions.bin

L’indirizzo della tabella delle partizioni (per impostazione predefinita 0x8000). Ti permette di spostare la tabella delle partizioni, dà più spazio per il bootloader. Si noti che potrebbe essere necessario modificare gli offset delle partizioni nel file CSV della tabella delle partizioni se questo valore è impostato su un valore superiore. Per fare in modo che ogni offset di partizione si adatti all’offset della tabella delle partizioni configurato, lasciare vuoti tutti gli offset di partizione nel file CSV.

Non elencato ma gestito per impostazione predefinita ota_data

Boot switch: la sezione ota_data può essere considerata semplicemente come uno switch, situato a 0xe000 in Flash. Determina se deve essere avviato app0 o app1. Lo switch stesso è il binario boot_app0.bin. Come dice Juraj, la dimensione di 2kB viene utilizzata anche per prendere appunti durante il flashing OTA.

0x10000 <sketch>/Blink.ino.bin

L’applicazione in app0 o app1 viene eseguita .

Genera solo file binario dello sketch

Come per il file Arduino HEX, possiamo generare solo il file binario. Innanzitutto, apri il tuo codice sorgente sul tuo IDE Arduino, compilalo per verificare gli errori, quindi seleziona Sketch -> Export compiled Binary,

esp8266 esp32 Arduino Export compiled binary IDE menu
esp8266 esp32 Arduino Export compiled binary IDE menu

quindi, facendo clic su Sketch -> Show Sketch Folder, puoi vedere cosa è successo.

Troviamo un nuovo file Blink.ino.doitESP32devkitV1.bin che è il nostro file binario compilato, che può essere utilizzato per gli aggiornamenti OTA o per condividere il firmware precompilato per semplificare il processo di flash per altre persone.

Ma se ricordi, nel caricamento che abbiamo visto prima, c’erano 4 file, non solo uno; questo perché qui trovi solo il file binario dello sketch.
