UART flooded with messages

Postby jenya7 » Sun Dec 05, 2021 7:07 am

The code

Code: Select all

void app_main()
{
    esp_err_t ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND)
    {
	     ESP_ERROR_CHECK(nvs_flash_erase());
	     ret = nvs_flash_init();
	}
	ESP_ERROR_CHECK(ret);

	esp_log_level_set("*", ESP_LOG_NONE);

	GPIO_Init();

	UART_Setup();
	UART_PrintString("UART setup done.\n");

	while (1)
	{

	}
}
After burning a bin and connecting to UART I constantly get messages like
rs?:0x10 (RT?WDT_RTC_R?SET),boot:0x1? (?PI_FAS?_FLASH_BO?T)
fl?sh rea? e?r, 1000
?ts_mai?.c 371
