FDS_PHY_PAGE_SIZE setting

[Dani]

Good morning,

In order to save some user data in flash, I want to fix page size to 32 bytes. It will be more useful for me, and it will be easier according to my project structure.

Now, I have setup the following parameters:

- In sdk_config.h:

FDS_VIRTUAL_PAGES 384

FDS_VIRTUAL_PAGE_SIZE 8 //32 bytes

- In fds_internal_defs.h:

FDS_PHY_PAGE_SIZE   (8)

The problem is that FDS_PHY_PAGE_SIZE definition is inside a file that belongs to a Softdevice file, so it will be modified when building the project with a new Softdevice version.

So, is there any way to include the FDS_PHY_PAGE_SIZE definition in a user-project file, as the 'sdk_config' file?

Best regards,

Dani

Hi again,

With the settings specified above, I'm able to read and erase a page, but I get 0x10 error when writting.

I have defined 'nrf_fstorage_t' according to this:

NRF_FSTORAGE_DEF(nrf_fstorage_t fstorage) =
{
/* Set a handler for fstorage events. */
.evt_handler = fstorage_evt_handler,

/* These below are the boundaries of the flash space assigned to this instance of fstorage.
* You must set these manually, even at runtime, before nrf_fstorage_init() is called.
* The function nrf5_flash_end_addr_get() can be used to retrieve the last address on the
* last page of flash available to write data. */
.start_addr = 0x000fd000,
.end_addr = 0x00100000,
};

Why do I get this error? Maybe is it related to the FDS_PHY_PAGE_SIZE?

Best regards.

Hi,

I'm not sure I understand what you mean.

FDS_VIRTUAL_PAGE_SIZE is defined in each config file of each project. See for example the config file of the flash_fds example in the SDK where it's defined as:

#ifndef FDS_VIRTUAL_PAGE_SIZE

#define FDS_VIRTUAL_PAGE_SIZE 1024

#endif

Which function returned 0x010 ?

Hi,

Finally I have left the PAGE_SIZE as the default value (1024). Furthermore I have noticed that the error I was getting was related to the data I wanted to write to flash: it's already solved. As I have seen, data to be written to flash has to be also aligned!!!!

Best regards.
