Use Nucleo STM32L4R5ZI-P as STM32L4R5ZI?

1

Hi to everybody, I’m new to PlatformIO.
I would like to use the Nucleo STM32L4R5ZI-P, but I noticed that only the Nucleo STM32L4R5ZI model (without -P) is supported.
Looking at the boards/nucleo_l4r5zi.json file, I noticed that the supported variants are “STM32L4xx/L4R5Z(G-I)T_L4R7ZIT_L4S5ZIT_L4S7ZIT,” where the “-P” model does not seem to be present.

How can I solve this?

TIA,
CP

  1. Create a new PlatformIO with any board (e.g., “Arduino Uno” and Framework “Arduino”)
  2. Create a new folder boards in the root of the project
  3. Create a new file boards/nucleo_l4r5zi_p.json with content

  },
  "url": "https://www.st.com/en/evaluation-tools/nucleo-l4r5zi-p.html",
  "vendor": "ST"
}
  1. Set the platformio.ini as
[env:nucleo_l4r5zi_p]
platform = ststm32
board = nucleo_l4r5zi_p
framework = arduino
  1. Set src/main.cpp as
#include <Arduino.h>
#define LED LED_BLUE /* or LED_GREEN or LED_RED */

void setup() {
  pinMode(LED, OUTPUT);
  Serial.begin(9600);
}

void loop(){
  Serial.println("LED toggling");
  digitalWrite(LED, HIGH);
  delay(1000);
  digitalWrite(LED, LOW);
  delay(1000);
}

And try to upload it.See if the LED blinks. If yes, it should be equivalent to the Arduino IDE setup to “Nucleo L4R5ZI-P”.

Thanks, it works!

Now I’ll try to adapt the previous project for the Nucleo F401RE (using the “stm32” framework)…
