Hello,

I'm currently trying out the Debugging features on ESP32 and have been following this guide successfully:
https://docs.espressif.com/projects/esp ... mmand-line

However, I have some issues/questions regarding breakpoints on Freertos functions. I'm currently testing on the example project blink under examples/get-started/blink.

Setting breakpoints in the code works fine for all the places except on row 46 at xTaskCreate:

Code: Select all

void blink_task(void *pvParameter)
{
    /* Configure the IOMUX register for pad BLINK_GPIO (some pads are
       muxed to GPIO on reset already, but some default to other
       functions and need to be switched to GPIO. Consult the
       Technical Reference for a list of pads and their default
       functions.)
    */
    gpio_pad_select_gpio(BLINK_GPIO);
    /* Set the GPIO as a push/pull output */
    gpio_set_direction(BLINK_GPIO, GPIO_MODE_OUTPUT);
    while(1) {
        /* Blink off (output low) */
        gpio_set_level(BLINK_GPIO, 0);
        vTaskDelay(1000 / portTICK_PERIOD_MS);
        /* Blink on (output high) */
        gpio_set_level(BLINK_GPIO, 1);
        vTaskDelay(1000 / portTICK_PERIOD_MS);
    }
}

void app_main()
{   
    printf("Hello testing..\n");
    xTaskCreate(&blink_task, "blink_task", configMINIMAL_STACK_SIZE, NULL, 5, NULL);
}

When i do this in GDB terminal with the command break 46, I get "No line 46 in the current file":

Target halted. PRO_CPU: PC=0x400D1E23 (active) APP_CPU: PC=0x400E2736

Temporary breakpoint 1, app_main () at ../main/blink.c:45
45 printf("Hello testing..\n");
(gdb) break 46
No line 46 in the current file.
Make breakpoint pending on future shared library load? (y or [n])

Why is it that gdb can't find line 46?? When I type "list" in gdb I can clearly see it's there:

(gdb) list
40 }
41 }
42
43 void app_main()
44 {
45 printf("Hello testing..\n");
46 xTaskCreate(&blink_task, "blink_task", configMINIMAL_STACK_SIZE, NULL, 5, NULL);
47 }
(gdb)

I'm using esp-idf v3.2.2 (stable) with OpenOCD v0.10.0-esp32-20190708

Any info on this would be much appreciated!
