Platformio configuration for Arduino GIGA R1

pio-arduinogiga

This repo contains a custom platformio board-configuration for Arduino GIGA R1. It is adapted from the board-definition for the Arduino IDE here.

Important: Modify platform-ststm32

The GIGA board requires a modification of the platform-ststm32 platform in the platform.py file.

Change the line

if board.startswith(("portenta", "opta", "nicla_vision"))

to

if board.startswith(("portenta", "opta", "nicla_vision", "giga"))

The platform.py file can be found in ~/.platformio/platforms/ststm32/platform.py on linux.

Uploading sketch

When flashing the Arduino GIGA using the Arduino IDE, the board is set to bootloader mode automatically. Using this board-definition in platformio will not do this. We need to set it into bootloader mode manually for now by double-pressing the RST-Button (Refer to the cheat-sheet)

Upload Troubleshooting

Sometimes the Arduino GIGA does not respond after flashing, it's not even possible to enter bootloader_mode by double-pressing the RST-Button. Workaround for this is to enter DFU-Mode by holding the BOOT0-button while powering the Arduino GIGA and then flash some sketch using the Arduino IDE, e.g.

#include <Arduino.h>
#include <Serial.h>
#define LED LED_BUILTIN

void setup() {
  pinMode(LED, OUTPUT);
  Serial.begin(9600);
}
void loop() {
  digitalWrite(LED, digitalRead(LED) ^ 1); // toggle
  Serial.println("Test");
  delay(1000);
}

After this, it's possible to enter bootloader_mode again.

Alternative workaround

A more fail-safe workaround is to use the arduino-cli to upload the .bin file created by platformio: arduino-cli upload -b arduino:mbed_giga:giga -i .pio/build/giga/firmware.bin
