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!
