Hi,

Yes, but this might require you to also adjust other partitions to avoid memory overlapping.

If you have any issues, please create a new ticket.

Hi Jared,

I notice that the default storage_partition=32KB. Could I configure the size to like 100KB?

Best regards,

Liza

Hi,

You have an overflow in your code.uint8_t type can only hold values from 0 to 255. If you assign this 1000 then you get an overflow, which results in an incorrect value being stored.

Try changing this to for example 250 and see if that fixes your issue,

Hi Jared,

I write int data = 1000 to NVS, and then read from NVS reading = 1000. But after resetting the device, the reading becomes 232. I don't know what's wrong.

Hi Liza,

As in the sample you would use the nvs_read() function to read the store data, after you have written it to NVS. The function takes in the ID and the data buffer the buffer where the data should be temporary stored in. Do you have any question related to this function?

Hi Jared,

I study the NVS sample. I want to ask how to read the stored data instead of the Number of bytes read?

Thanks,

Liza
