nRF Connect SDK Intermediate - Lesson 9 (DFU/MCUboot, formerly Lesson 8), exercise 2 solutions won't compile for nRF7002DK

Saxman58

I've had trouble getting the MCUboot to compile for our application which runs on the nRF7002DK board, and I have similar trouble with the Lesson 8 examples on the nRF7002DK board.  They worked fine on an nRF52833 board (except for the lack of a serial Flash).  I am using NCS v2.6.1.

Why can't I even get your solutions to compile for this board?

Here is the output when I build the exercise 2 solution from Nordic for an nrf7002dk_nrf5340_cpuapp target:

Why do these work for the nRF52833DK, but not the nRF7002DK?  The nRF7002DK is listed as a board that should work since it has USB.

    I also tried this with NCS v2.6.2.  Same results.  I can build the solutions for Exercise 1 for the nRF52833DK, nRF52840DK and nRF5340DK boards, but not the nRF7002DK.  For Exercise 2 the nRF52833DK doesn't work because it doesn't have the serial flash, but nRF52840DK and nRF5340DK work and again nRF7002DK does not.

    An update:  When I changed CONFIG_PM_PARTITION_SIZE_MCUBOOT to 0x20000 as suggested in the lesson I was able to get it to compile and work.  I am confused about a few things, however, that might be worth clarifying in the lesson text for v2.6.x:

    Exercise 2, step 8 gives a broken link to https://github.com/nrfconnect/sdk-nrf/tree/main/samples/net/aws_iot/child_image/mcuboot/boards which should give more information about how to configure to use SPI for the external Flash instead of QSPI since the QSPI is connected to the nRF7002 chip.  I found this under the sysbuild folder that looks mostly like what you have in the `child_image/mcuboot/boards` folder in the solution.

    In the `nrf7002dk_nrf5340_cpuapp.conf` file in the `child_image/mcuboot/boards` folder in the solution, the CONFIG_PM_PARTITION_SIZE_MCUBOOT value is set to 0x10000.  If I had to change this to 0x20000 in the `mcuboot.conf` to get the nRF7002dk build to work, why is it 0x10000 in the nRF7002dk specific config file?  I would have thought that board specific settings would take precedence over the more general settings in `mcuboot.conf`, but apparently not since the generated `autoconf.h` file has the 0x20000 value.

    So if `child_image/mcuboot.conf` file takes precedence over the `child_image/mcuboot/boards/nrf7002dk_nrf5340_cpuapp.conf`, then the `CONFIG_PM_PARTITION_SIZE_MCUBOOT=0x10000` setting is ignored, and the `CONFIG_BOOT_MAX_IMG_SECTORS=256` setting is redundant.

    It seems odd that the board specific config file can add new config settings, but not override the more general settings in `mcuboot.conf`.

    So now that I have a working example, I can go back to figuring out why MCUboot is a problem to add to our app.  But I am curious about the above questions about config setting precedence.  How would one go about overriding a setting just for a particular board?  (For our app I'll just make all the settings in the mcuboot.conf to keep it simple.)

    Hi Glen,

    Thanks for the report! I have reported this to our DevAcademy team and they will get it fixed so the lesson works for the nRF7002DK as well.

    Yea this is a oversight from us. When I wrote this lesson I assumed that the board file should take precedence over mcuboot.conf, but if you see the oppsosite I assume it does not do that.

    Instead, if you want to use the board file, you have to have child_image/mcuboot/prj.conf which overwrites the mcuboot default config. So I suggest that you copy this prj.conf into child_image/mcuboot/prj.conf.

    However, since you likely just use one board, it is simpler to just have it all in mcuboot.conf. We just try to make it more flexible to make the solution work for more different boards.

    PS:
    In v2.7.0 and later we have updated to Sysbuild! If you intend to update your application soon, I suggests learning that method instead. While it is similar, it differs in some ways as well.
    And we just released Lesson 8 on just Sysbuild, which will hopefully help with these things as well.

    We are also working on updating Lesson 9 to Sysbuild now. E1-E3 are already updated.

    Thanks, Sigurd.  I did decide to put everything in mcuboot.conf since we just have one board, but it is good to see the technique for supporting multiple boards in the MCUboot build.

    And thank you for the new prj.conf.  That has some good tips for how to shrink the MCUboot size further, which may become important as our application grows.
