Try removing the call to pstorage_init() in your code. As described in the documentation, initialization should be performed only once. From the source code of the mbed-os source code for SecurityManager, pstorage_init() is called inside SecurityManager().init(). This issue is also discussed in this thread.

@Jørgen Holmefjord

i have tried "Could you try ti increase PSTORAGE_MAX_APPLICATIONS to 4 pages and then only request 1 page for pstorage?" but the result was not as expected. i have changed the question with the result at this situation.

Could you try ti increase PSTORAGE_MAX_APPLICATIONS to 4 pages and then only request 1 page for pstorage? Most likely security manager is using pstorage as well to store bonding information, but you have allready requested all available pages for your flash storage, leaving no available pages for bonding storage.

no PSTORAGE_MAX_APPLICATIONS is increased only when 4 pages are requested. PSTORAGE_MAX_APPLICATIONS is one when one page requested.

Jørgen Holmefjord — Thu, 23 Mar 2017 14:20:57 GMT

But did you increase PSTORAGE_MAX_APPLICATIONS to 4 before you only requested 1 page?

i have requested 1 page first. that is shown in the attached images . first i stored my data in that page.that is shown in first image. but after bonding the data is overwritten by bonding information shown in second image.

when four pages are requested. when one device bonded the data will store at the starting of first page just like the second image . after that if a second device is bonded that bonding information will store at the starting of second page and so on..

PSTORAGE_MAX_APPLICATIONS set the number of pages to be allocated for the pstorage module. Have you tried requesting less than 4 pages in pstorage to allow security manager to request the pages it needs as well? By "after that each time a new device is bonded, the bonding information are stored at the starting of each page.", do you mean that for each connected device, the bonding information is stored on a new page in flash?
