I change the address to 0x27000 and it could write data to flash after fstorage initialization. But I also meet a strange problem. I get the data from uart then write to the flash, it couldn't write to flash. The clear and write function havn't return any error. Also I have delay 100ms then to read the data after writing. What problem do you think? Thanks.

Those look fine. Does it work now? If not, what error do you get?

Now I set start_addr to 0xFD000 and end_addr to 0xFFFFF in the fstorage instance, then I write data at 0xFD000 or 0xFD100. Is there any problem with the address? I couldn't understan it.

Hi Alice, I will try one last time:

You should try to write to an address within the start_addr and end_addr that you have set in the fstorage instance. Good luck.

In the attached file I see you set the start_addr to 0xFD000 and try to write at address 0xFC000....

You set the instance start_addr to 0xFD000 then you define FLASH_ADDR to 0xFC000 and pass that to nrf_fstorage_write(), this is wrong. Am I explaning myself?

Yes. I also try to set the start_addr to 0xFD000 and try to write at 0xFD000 or other address, it also couldn't write data to flash. I have attached the function, could you help me have a look?

You can't set the start_addr to 0xFD000 and try to write at 0xFC000, right?

The error 0x10 is NRF_ERROR_INVALID_ADDRESS, from the documentation for nrf_fstorage_write():

@retval NRF_ERROR_INVALID_ADDR If the address dest is outside the flash memory boundaries specified in p_fs, or if it is unaligned.

It returns 0x10 error.The NRF_FSTORAGE_DEF init a instance to use address from 0xFD000, why FLASH_ADDR start at 0xFC000?

Could you at least provide the value returned by those functions?

Yes, I have read the migration notes of SDK 14 for the fstorage and do as the experimental Flash Storage, but it couldn't write data to the flash. Could you help me have a look as the attachment? Thanks.
