nrf5340 XIP with mx25l25645g

[LucosidE]

Hello, 

We are trying to get the XIP example working with a custom nrf5340 board with the mx25l25645g memory chip.
Using VSCode, 2.7.0 toolchain, 2.7.0 sdk  

The project builds successfully but gets stuck on checking image validity, never progresses any further and I have to kill the terminal.

[ #################### ] 1.177s | Verify file - Done verifying
[ #################### ] 0.035s | Check image validity - Finished
 

The pinout for the custom board exactly matches the development kit:

qspi_default: qspi_default {

        group1 {

            psels = <NRF_PSEL(QSPI_SCK, 0, 17)>,

                <NRF_PSEL(QSPI_IO0, 0, 13)>,

                <NRF_PSEL(QSPI_IO1, 0, 14)>,

                <NRF_PSEL(QSPI_IO2, 0, 15)>,

                <NRF_PSEL(QSPI_IO3, 0, 16)>,

                <NRF_PSEL(QSPI_CSN, 0, 18)>;

            nordic,drive-mode = <NRF_DRIVE_H0H1>;

        };

    };

I have defined qspi as follows following the mx25l25645g datasheet:

&qspi

{

    status = "okay";

    pinctrl-0 = <&qspi_default>;

    pinctrl-1 = <&qspi_sleep>;

    pinctrl-names = "default", "sleep";

    mx25l25: mx25l25645g@0

    {

        compatible = "nordic,qspi-nor";

        reg = < 0x0 >;

        writeoc = "pp4io";

        readoc = "read4io";

        sck-frequency = < 6000000 >;

        jedec-id = [ C2 20 19 ];

        sfdp-bfp = [ e5 20 fb ff  0f ff ff ff  44 eb 08 6b  08 3b 04 bb

                     fe ff ff ff  ff ff 00 ff  ff ff 44 eb  0c 20 0f 52

                     10 d8 00 ff  d6 59 dd 00  82 9f 03 db  44 03 67 38

                     30 b0 30 b0  f7 bd d5 5c  4a 9e 29 ff  f0 50 f9 85 ];

        size = < 0x10000000 >;

        quad-enable-requirements = "S1B6";

        has-dpd;

        t-enter-dpd = < 0x2710 >;

        t-exit-dpd = < 0x88b8 >;

        enter-4byte-addr = <0xb7>;

        address-size-32;

    };

};

With this definition we are able to read and write to the flash but are not able to use XIP. 

Any tips for solving this issue are appreciated, at this point I am out of ideas. 

Thanks you.

Hello,

I apologize for the delay in my response; I was away for the past two days attending some workshops.

Are you working with any of the samples from the SDK, or is this your own custom application? Have you tried the SMP server with the external XIP sample?

Kind regards,
Abhijith

That is the sample we are using, the only change is the &qspi node definition for the mx25l25645g chip. 
We have used another application to test that we can read and write to the external flash using that &qspi node definition and that works without any problems.
