PSTORAGE_MAX_APPLICATIONS and actual flash pages reserved in pstorage_register

[tumaku]

I have one doubt after reading the definition of PSTORAGE_MAX_APPLICATIONS and PSTORAGE_DATA_START_ADDR in pstorage_platform.h and the actual computation of used flash memory in pstorage_register() method in pstorage.c

It seems that PSTORAGE_DATA_START_ADDR assumes that an application will use one and only one flash page while the register method allows for more than one flash page per application (dynamically computed based on block size and number of blocks).

Am I missing anything? Can an application use more than one flash page?

Hi

How to read the allocated flash space is described here.

Your observation is correct. An application (module) can use more than one flash page. The PSTORAGE_MAX_APPLICATIONS must be increased in accordance to the number of flash pages used by all applications (modules). The PSTORAGE_MAX_APPLICATIONS is rather the number of flash pages used for the whole application code instead of how many modules use the flash.
