Reduce flash write_block_size

[Shikamaru]

HI,

    I am working on nrf52833 board, while working with flash in dts file i could see that write_block_size is 4 bytes. Is there any way to reduce that , i need it as 1 byte. kindly suggest me

Hi Shikamaru,

Thank you for contacting DevZone at NordicSemi.

You want to reduce the write_block_size. For that, you could use overlay file for your board.

Here is sample overlay:

&flash0 {
    write-block-size = <1>;
};

Here is sample DTS output using such an overlay file. 

I hope it helps.

Regards,

Naeem

thanks Naeem Maroof ,

                      Yes this one I have tried already. it will get update is .dts file (zephyr.dts ). However , while writing flash if I provide one byte it won't take it. it will generate error.

How are you writing? 

Can you provide the code / zip-folder and log file if any.

I will try that here.
