是ESP-IDF(Espressif IoT Development Framework)中 NVS(Non-Volatile Storage)模块返回的一个错误代码。下面是对该错误的详细解释、可能原因、解决方法以及预防建议。 1. esp_err_nvs_not_found 错误的含义 esp_err_nvs_not_found 错误表明在尝试访问 NVS 中的某个键值对时,该键值对不存在。这通常发生在读取或...
certificate and key to be used for secure connection with MQTT. I'm able to provision a board, and it connects successfully to a secured MQTT broker, but, if I modify that example project to write some data to NVS storage, I'm always getting an error 0x1102 (ESP_ERR_NVS_NOT_FOUND)...
After a resetting ESP32 I get an ESP_ERR_NVS_NOT_FOUND when I try to read the committed data: Code:Select all nvs_handle handle;// Openesp_err_terr = nvs_open(APP_SETTINGS_NAMESPACE, NVS_READWRITE, &handle); ESP_ERROR_CHECK(err);if(err != ESP_OK) {return; }size_trequired_siz...
i have a working project that uses nvs. if i do a idf.py erase-flash and reflash the project, NVS don't work anymore because when i do Code:Select all esp_err_terr =nvs_open("storage", NVS_READONLY, &my_handle); it return ESP_ERR_NVS_NOT_FOUND. ...
while checking the logs I found that "err =nvs_set_i32(my_handle, "res", restart_counter);" works fine but "err =nvs_get_i32(my_handle, "res", &restart_counter);" Gives error "ESP_ERR_NVS_NOT_FOUND" The same example working correctly onESP32-Wroom-32D and ESP32-S2 ...

一、NVS简介 官网文档地址 1. 存储类型 nvs是在Flash中存储键值对数据,适合存储小规模的数据,不适合存储大的数据。 写键值对时,key 的最大长度为154个字符, 值支持常用的数据类型, 如: uint8_t int8_t uint16_t int16_t uint32_t int32_t
ESP_ERR_NVS_NOT_FOUND was happening to me because I was calling esp_reset() just after a write to the nvs. I am writing 1064 bytes using nvs_set_blob in a 0x14000 size unencrypted nvs partition with a single blob_key. I tried using CONFIG_SPI_FLASH_VERIFY_WRITE but this did not ...
如果使用默认的nvs分区操作,这一步可以不用。 2. 擦除NVS空间 (1)删除默认分区 函数定义 esp_err_t nvs_flash_erase(void) 删除名称为"nvs"的默认nvs分区。如果分区已经被初始化了,则先要执行反初始化。 返回值 ESP_OK on success ESP_ERR_NOT_FOUND 分区表中没有找到"nvs"空间 其它值很少出现 (2)删除...
