reducing to the least common denominator… can’t get printf to work on ESP32-S2 with framework = espidf, arduino This works with ESP32-S3
platformio:
[env:lolin_s2_mini]
platform = espressif32
board = lolin_s2_mini
framework = espidf, arduino
main.cpp
#include <Arduino.h>
#include <stdio.h>
#include "sdkconfig.h"
void setup()
{
printf("Hello World\n");
}
void loop()
{}
errors:
