Unable to save image to slot 1 (External QSPI Flash) on nRF52840

[Moh]

Hi ,

I am trying to implemenent DFU on nRF52840. Aim is to store new image to slot on QSPI external flash but it seems like nothing is sored on slot 1 as when I upload image via DFU manager, nothing is on slot 1. Please confirm my dts, mcuboot and prj.conf files. Thanks Moh

Hello,

You can add/edit the configuration of mcuboot file in the following way:

CONFIG_BOOT_MAX_IMG_SECTORS=512
CONFIG_MULTITHREADING=y
CONFIG_MAIN_STACK_SIZE=10240
CONFIG_LOG_MODE_MINIMAL=y

You need  add this to your DTS file to properly identify the external flash for the partition manager

chosen {
nordic,pm-ext-flash = &at25xe32;
}

If you're using a different flash chip (AT25XE321D) than the default one (MX25R6435F) that comes with the nRF52840 development kit, you should delete the default flash node in your devicetree overlay.

&qspi {
    /delete-node/ &mx25r64;
    status = "okay";
    pinctrl-0 = <&qspi_default>;
    pinctrl-1 = <&qspi_sleep>;
    pinctrl-names = "default", "sleep";
    
    at25xe32: at25xe321d@0 {
        /* Your existing configuration */
    };
};

After adding the above-mentioned configuration and changed in the DTS file, you can try to run the sample again and let us know.

Thanks.

Hi Kazi,

I have made above suggestions. When I upload the image via Device Manager or nrf Connect app, I got the error Hash not Found (8). I am using the custom board based on nRF52840. See the updated files changes below. Thanks Moh
