launch_core1 does not work

[Ing-Dom]

Hi,

I wanted to manually lauch core1 with the SDK function multicore_launch_core1(loop_core1);
I do this at the end of setup();

void loop_core1() { //_hwsensors.Loop(); delay(200); digitalWrite(10, HIGH); delay(200); digitalWrite(10, LOW); }

It does not work. It seems that loop_core1 is not executed.

when I rename loop_core1 to loop1 and do not lauch ot manually, it works.
Why does the manual launching not work? Any idea?

The reason I want to do this is that I want to setup everything first and then start the 2. core. If they are started simultaenusly i would have to add some sync.

edit: sorry, I just got it... I forgot the while(true)...

[RISC-E-Biscuit]

From the arduino pico library examples. Seems to work.

// Demonstrates a simple use of the setup1()/loop1() functions
// for a multiprocessor run.

// Will output something like, where C0 is running on core 0 and
// C1 is on core 1, in parallel.

// 11:23:07.507 -> C0: Blue leader standing by...
// 11:23:07.507 -> C1: Red leader standing by...
// 11:23:07.507 -> C1: Stay on target...
// 11:23:08.008 -> C1: Stay on target...
// 11:23:08.505 -> C0: Blue leader standing by...
// 11:23:08.505 -> C1: Stay on target...
// 11:23:09.007 -> C1: Stay on target...
// 11:23:09.511 -> C0: Blue leader standing by...
// 11:23:09.511 -> C1: Stay on target...
// 11:23:10.015 -> C1: Stay on target...

// The normal, core0 setup
void setup() {
Serial.begin(115200);
delay(5000);
}

void loop() {
Serial.printf("C0: Blue leader standing by...\n");
delay(1000);
}

// Running on core1
void setup1() {
delay(5000);
Serial.printf("C1: Red leader standing by...\n");
}

void loop1() {
Serial.printf("C1: Stay on target...\n");
delay(500);
}
