接前一篇文章：ESP32-C3模组上跑通NVS（6）

上一回讲到乐鑫技术支持发来了操作自定义NVS分区的代码。本回就对于代码进行详细解析，并通过此过程看一下具体应如何进行正确的操作。下边就开始代码分析：

主函数

主函数即app_main()代码如下：

void app_main(void)
{esp_err_t err = nvs_flash_init_partition(STORAGE_PARTITION);if (err == ESP_ERR_NVS_NO_FREE_PAGES || err == ESP_ERR_NVS_NEW_VERSION_FOUND) {// NVS partition was truncated and needs to be erased// Retry nvs_flash_initESP_ERROR_CHECK(nvs_flash_erase());err = nvs_flash_init_partition(STORAGE_PARTITION);}ESP_ERROR_CHECK( err );uint32_t count = 0;/* Read the status of GPIO0. If GPIO0 is LOW for longer than 1000 ms,then save module's run time and restart it*/while (1) {err = save_blob_t
