How to store a .fw image in internal flash in NCS

user2315

We need to store a .fw firmware (or any binary/hex) image for an external device hanging off the nRF52833 in internal flash.

What is the best way to integrate the image into the nRF application image?  

Is there an example someone can point me to that I am not seeing?

    Sorry, I wasn't very clear.  This is an image that the nRF52 will store in its internal flash.  When the nRF52 starts, it will send that image to another device on the board via I2C.  The image would be an header (*.h) file in the format like:

    const unsigned char firmware_image[] = {
    0x2b, 0x66, 0x0, 0x0, 0x0, 0x0, 0x67, 0x17, 0xa3, 0x27, 0x19, 0x5d,
    0xd2, 0x1b, 0x19, 0xb2, 0x2e, 0xc8, 0x39, 0xde, 0x2c, 0x97, 0xd9, 0xfb,
    0x7e, 0xbb, 0x8b, 0xc9, 0x54, 0x33, 0x8c, 0x19, 0xe4, 0x2a, 0x5c, 0x6c,
    0x8d, 0x5f, 0x98, 0xe, 0x0, 0x0, 0x0, 0x0, 0x45, 0xc3, 0xda, 0x85,
    0xe8, 0xbc, 0x7c, 0x3e, 0xdf, 0xfa, 0xb5, 0x29, 0x39, 0x35, 0x86, 0xad,
    0x0, 0x0, 0x0, 0x0,
    };

    I want to be able to put this image in a specific location in nRF52 flash during the build.  This was fairly easy with the old SDK.  All of us here are still learning the NCS environment.  Thanks for the assistance!

    Perfect!  That is what I needed.
