sd_flash_write writes corrupted data when BLE is enabled

[David]

Hi,

I wrote some code that writes to the flash perfectly when BLE is not enabled but when it is enabled, some of the data are correct while others are either missing or shifted to a later address. Below is a snippet of the code:

uint32_t retval;
while(NRF_ERROR_BUSY == (retval = sd_flash_write(p_dst, p_src, num_words)));
ASSERT(NRF_SUCCESS == retval);

I'm trying to avoid pstorage since I'm want to write to a contiguous block of flash much greater then the page size.

Thanks.

I think the write flash require you to write per page only. You cannot cross the page boundary. What you are experiencing look like cross boundary issue. Try pstorage_store, it handle cross boundary for you. I think, can't confirm at the moment. You can try and see.

SDK uses pstorage to store bond data. In many examples you can find that the pstorage is initialized in device_manager_init. Exactly where it stores its data I have no idea. It is managed by pstorage. before you can use pstorage you need to allocate space for it. I haven't touch this part of the code for a long while. Don't know how much has been changed then.
