[TW#24593] Complete allocated NVS partition not available

[hvishu]

I have attached the modified blink project. I have allocated 36K (in partition.csv), but when I try to get the nvs allocated I get 23K.

How do we calculate the available NVS data for the app from the allocated done through partition table?

You should not expect to be able to store 36 1k blobs in a 36k nvs partition. There is an overhead. 36k is 9 pages, 1 page must be free so you have 8 pages and with overhead you can store 3 blobs per page so 3*8=24.
