RTC_NOINIT not starting variable

[urbanze]

Why when I create variable with RTC_NOINIT, value is not equal than expected (222 in this example)?
This always are create with (random?) value after non-sw reset, but I expect 222.

Code: Select all

RTC_NOINIT_ATTR uint32_t lol = 222;



extern "C" void app_main()
{
	ESP_LOGI("Before", "%d", lol);

	lol++;

	ESP_LOGI("After", "%d", lol);

	vTaskDelay(pdMS_TO_TICKS(500));
	esp_restart();
}

Terminal output:

ps* What "0x400802f8: _NMIExceptionVector at ??:?" mean? This appear after updated to IDF v3.2-dev-144-g6ee3cf67?

Code: Select all

How can it be init to 222 if it is no_init? You can check reset reason and decide whether to init in app_main

....Yeah, this make a little sense, my mistake, sorry and thanks to remember to check reason.
Do you have all reasons can be erase no_init? I think is all except sw...
