Core 0 panic'ed (IllegalInstruction) due to xTaskCreatePinnedToCore

Postby Mykyta_Mar » Thu Jan 18, 2024 10:56 am

Hi, I trying to start a task on core 0, but it leads to core panic.
//my task:

TaskHandle_t gh_xTask_1 = NULL;
static volatile uint64_t idle1Calls = 0;

static void idle_task_1()
{
idle1Calls++;
}

//task initialization:
xTaskCreatePinnedToCore(idle_task_0, "perfC0", 2048, NULL, 1, &gh_xTask_1, 0);

Error:
Guru Meditation Error: Core 0 panic'ed (IllegalInstruction). Exception was unhandled.

Task functions must never return. Add a `vTaskDelete(NULL);` at the end of your task function.

See https://www.freertos.org/a00125.html for more details.
