NRF_FSTORAGE_DEF issue with nRF52810

[BLEPRODUCT]

Hi,

I'm using S112 v6.1.1 with SDK 15.3.0 on nRF52810.( I don't use bootloader )

I tried to search examples for using fstorage api on it.

But I couldn't get anything.( even in SDK examples, there is only for nRF52832 )

My application address range is below:

0x19000 - 0x2A2F8

I think I can use 0x2B000 ~ 0x2FFFF for fstorage.

But it didn't work.

Is it impossible to use fstorage on nRF52810?

Could anyone give me some advice? Thanks.

Hi

Please see our user guide for how to transfer PCA10040 projects to nRF52810 hardware. That should be sufficient to make the fstorage example work on your nRF52810 board.

Best regards,

Thank you for reply, Simonr.

But my question was not about immigration from nRF52832 to nRF52810.

In fstorage example, NRF_FSTORAGE_DEF is below:

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 = 0x3e000,
    .end_addr   = 0x3efff,
};

start_addr is 0x3E000 and end_addr is 0x3FFFF.

That doesn't make sense on nRF52810.

As I know, nRF52810 has only 192kb flash memory( = 0x30000 )

So my question was how can I set the start_addr and end_addr to use fstorage on nRF52810.

Okay, sorry about the misunderstanding. I thought you were having trouble making the application run on your nRF52810. Seeing as your application only extends to 0x2A2F8, you should indeed be able to use the remainder of the Flash memory for fstorage. Have you tried editing the start and end addresses in NRF_FSTORAGE_DEF to, for example, 0x2B000 and 0x2F000 respectively?

Thank you for reply.

Yes, I tried editing the start and end addresses so many times as  different values.

0x2B000 - 0x2F000 / 0x2B000 - 0x2CFFF / 0x2C000 - 0x2DFFF or etc.

I am using lesc with peer manager and I noticed that peer manager is using fds.for this.

I guess this must be related to this problem.

[Simonr]

What kind of problems are you encountering when you try these values (any error codes of some kind)? If the fstorage files and header files aren't in your project it makes sense that you're struggling. If your application already uses the FDS module, you might have more luck storing data using the Flash Data Storage library to store data in flash in that case.

Best regards,

Simon
