ESP32 store calibration data failed(0x1105)

Postby zazas321 » Wed Jan 19, 2022 9:24 am

Hello. I have been developing on the ESP32 as usual and noticed that I am getting this error and a warning. I have not noticed this before.
The error happens when I initialise BLE:

Code: Select all

I (3922) BTDM_INIT: BT controller compile version [6a07b06]
I (3922) system_api: Base MAC address is not set
I (3922) system_api: read default base MAC address from EFUSE
I (3932) phy_init: phy_version 4670,719f9f6,Feb 18 2021,17:07:07
W (4092) phy_init: saving new calibration data because of checksum failure, mode(0)
E (4442) phy_init: store_cal_data_to_nvs_handle: store calibration data failed(0x1105)
I use custom partition table (my ESP32 is 8MB flash version)

Code: Select all

nvs,      data, nvs,     0x9000,  0x4000,
otadata,  data, ota,     0xd000,  0x2000,
phy_init, data, phy,     0xf000,  0x1000,
factory,  app,  factory, 0x10000,  0x200000,
ota_0,    app,  ota_0,           , 0x100000,
ota_1,    app,  ota_1,           , 0x100000,
Could someone help me understand why would this happen?


This is my app_main:

Code: Select all

 app_main(void)
{
    static httpd_handle_t server = NULL;
    esp_err_t ret;
    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);
    ADC_Init();
    NVS_open();
    SPI_init_eeprom();
    EEPROM_setup();
    spi_mutex = xSemaphoreCreateBinary(); /
    xSemaphoreGive(spi_mutex); // give the semaphore immediately after creating so that my task can take it
    i2c_mutex = xSemaphoreCreateBinary(); // i2c mutex decalred as extern global in PCA9539
    xSemaphoreGive(i2c_mutex); // give the semaphore immediately after creating so that my task can take it
    i2c_setup(); // this setups i2c bus and setups all the required pins
    BLE_setup();//happens if this is called
    UART1_setup();


    xTaskCreate(UART0_task,"UART0_task",5000,NULL,1,NULL); // receiving commands from main uart


}

my BLE_setup :

Code: Select all

void BLE_setup()
{
    printf("BLE SETUP \n");
    esp_err_t ret;
    ESP_ERROR_CHECK(esp_bt_controller_mem_release(ESP_BT_MODE_CLASSIC_BT));

        printf(str);
        if (i < 5){
            printf(":");

Re: ESP32 store calibration data failed(0x1105)

UPDATE:

I have confirmed that this is only happening to one device that I was using the most. The other devices when flashed with the exact same code does not produce this error so this must be hardware related issue.

1.Is it possible that I have somehow managed to corrupt it? What could have possibly gone wrong that this only happens to this device but not others

2. What exactly this error means? Even though this error happens (I havent done extensive testing ), my program seems to be running as usual. What problems could this cause me?

0x1105 = ESP_ERR_NVS_NOT_ENOUGH_SPACE
Calibration data is almost 2kB, your NVS partition is small, and you use this particular device a lot. NVS is full.

https://docs.espressif.com/projects/esp ... alibration
Full calibration is relatively slow and uses a lot of power. Given this data can't be saved and restored, this will need to be done every time WiFi/BT is initialised (ie. every boot/wake).

Thank you very much for the response. I have some additional questions

1. What is this calibration data exactly? How important is it for the program? Can it work without this?

2. Can I just simply allocate a few more KB in my partition. Would that fix the issue? Is it only temporary fix?

3. Does it fill up overtime? Why is it not full on some other devices.?

1. speedup system start, as its faster to read calibration data rather than do it every time
2. sure, but you will have to move nvs partition to the end of flash or change all partitions offset
3. its because, like you said, the device you are working with most the time; the nvs partition is most likely full of other stored values from other projects; idf.py erase_flash should fix it

PS what is your flash size, because you are allocating more than 4MB

It's not documented, unfortunately. Some kind of tuning parameters for RF transmission vs power.

If you'd like this to change, please add a comment here: https://github.com/espressif/esp-idf/issues/7324
NVS failure is another good case.

This is concerning me because once I finish programming the device, it will be out on the field doing what its supposed to do and I dont this to cause me some trouble later. So my 2 solutions are:

1. Increase the size of the partition for the PHY (I assume this is only temporary because it is going to fill overtime)
2. call esp_phy_erase_cal_data_in_nvs() before initialising WiFi or BLE

PHY calibration is done only one time, so it wont fill over time.
If you afraid of that then maybe leave this nvs partition just for that (and some wifi stored data) and to have another NVS partition you could use for all data you will store in app?

Can you clarify what do you mean? I thought tahts wht I have:

Code: Select all

vs,      data, nvs,     0x9000,  0x4000,
otadata,  data, ota,     0xd000,  0x2000,
phy_init, data, phy,     0xf000,  0x1000,
factory,  app,  factory, 0x10000,  0x200000,
ota_0,    app,  ota_0,           , 0x100000,
ota_1,    app,  ota_1,           , 0x100000,
I have 2MB for the app and just 0x4000 for the nvs.
