What is the actual behavior?

%lld cannot be displayed correctly on esp32c2 (XTAL=26MHz)

Steps to reproduce.

Build this code to esp32c2(26MHz XTAL)

#include <stdio.h>
#include <inttypes.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_log.h"
#include "esp_timer.h"
#include "rom/ets_sys.h" // ets_get_cpu_frequency()

static const char *TAG = "MAIN";

void app_main()
{
#ifdef CONFIG_IDF_TARGET_ESP32
    ESP_LOGI(TAG, "Core is ESP32@%"PRIu32"Mhz", ets_get_cpu_frequency());
#elif defined CONFIG_IDF_TARGET_ESP32S2
    ESP_LOGI(TAG, "Core is ESP32S2@%"PRIu32"Mhz", ets_get_cpu_frequency());
#elif defined CONFIG_IDF_TARGET_ESP32S3
    ESP_LOGI(TAG, "Core is ESP32S3@%"PRIu32"Mhz", ets_get_cpu_frequency());
#elif defined CONFIG_IDF_TARGET_ESP32C2
    ESP_LOGI(TAG, "Core is ESP32C2@%"PRIu32"Mhz", ets_get_cpu_frequency());
#elif defined CONFIG_IDF_TARGET_ESP32C3
    ESP_LOGI(TAG, "Core is ESP32C3@%"PRIu32"Mhz", ets_get_cpu_frequency());
#elif defined CONFIG_IDF_TARGET_ESP32C6
    ESP_LOGI(TAG, "Core is ESP32C6@%"PRIu32"Mhz", ets_get_cpu_frequency());
#elif defined CONFIG_IDF_TARGET_ESP32H2
    ESP_LOGI(TAG, "Core is ESP32H2@%"PRIu32"Mhz", ets_get_cpu_frequency());
#endif
    int64_t time = esp_timer_get_time();
    ESP_LOGI(TAG, "time=%lld us", time);
}

You probably have CONFIG_NEWLIB_NANO_FORMAT enabled (as it is enabled by default on C2). Please try disabling, then 64-bit formatting should work.

Thank you for your reply. I changed it and confirmed it works fine. esp32c2-nano-format-2

I (386) MAIN: Core is ESP32C2@120Mhz
I (386) MAIN: time=396460 us

I would like it to be disabled by default in C2 as well.
