esp _log.h causes random TG1WDT_SYS_RESET / RTCWDT_RTC_RESET in C++

Postby leenowell » Sun Jan 24, 2021 2:02 pm

Hi All,

I have been having random resets (TG1WDT_SYS_RESET followed by RTCWDT_RTC_RESET) and core dumps. From the logging, I could see the odd corrupt characters but could not work out what is corrupting it. I have now been able to reproduce it with a minimal test and the results are a bit odd.

The code is as follows

Code: Select all

extern "C"
{
	#include "esp_event.h"
	#include "driver/gpio.h"
	void app_main(void);
}
#include "esp_log.h"

void app_main(void)
{
	ESP_LOGI("app_main", "PowerOn");
#define m_rstPin 	 GPIO_NUM_5
#define m_pwkeyPin 	 GPIO_NUM_4
#define m_powerPin	 GPIO_NUM_23
#define m_txPin		 GPIO_NUM_27
#define m_rxPin		 GPIO_NUM_26

	ESP_ERROR_CHECK(gpio_set_direction(m_powerPin, GPIO_MODE_OUTPUT));
	ESP_ERROR_CHECK(gpio_set_level(m_powerPin, 1));

	vTaskDelay(3000 / portTICK_RATE_MS);
    while (1)
	{
	    vTaskDelay(3000 / portTICK_RATE_MS);
	}
}
and the log is

Code: Select all

If I then move the "#include "esp_log.h" to inside the "extern C" block like this

Code: Select all

extern "C"
{
	#include "esp_event.h"
	#include "driver/gpio.h"
        #include "esp_log.h"
	void app_main(void);
}
it works fine with the following log.

It would appear that despite compiling OK, there is some issue with esp_log.h being included in C++?

git describe on esp_idf gives me

Code: Select all

$ git describe
v4.2
Would appreciate your thoughts - it has taken days to narrow it down to this :)

thanks

Lee.
