Problem Description
When running the sketch below and using nonos-sdk 2.2.1 or 2.2.2, the sketch crashes. It works fine with nonos-sdk pre 3. I confirmed this on another computer with a fresh install of Arduino. It works when the char[] is not in PROGMEM.
MCVE Sketch
const char someMessage[] PROGMEM = "Some Message";
void setup() {
Serial.begin(115200);
Serial.println(someMessage);
}
void loop() {
}
