Trouble migrating from NCS 2.6 to 2.8

[BrianW]

Due to issues with the wifi stack, I have to move my project from 2.6 to 2.8.

I downloaded the new tools set (toolchains\cf2149caf2) and new nordic connect version 2.8.0 as per

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/installation/updating.html

I read the migration guides for 2.7 and 2.8, and the 'using sysbuild for multi-image builds guides:

https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/build/sysbuild/index.html#sysbuild

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_sysbuild.html

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_guide_2.8.html

Mostly this gave me a headache.

I created sysbuild.conf (at the root where I run west - is this right?), and filled in the stuff from the migration guides for mcuboot and nrf70 support.

# MCU boot config now handled by sysbuild
SB_CONFIG_BOOTLOADER_MCUBOOT=y

# put slot2 in external flash
SB_CONFIG_PARTITION_MANAGER=y
SB_CONFIG_PM_MCUBOOT_PAD=y
SB_CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y

I updated my prj.conf for the changes to nrf70 config option names

I created sysbuild/mcuboot and copied in the prj.conf from the previous child_image/mcuboot.conf

There was already a sysbuild/hci_ipc/prj.conf, I updated it with changes I had made to child_image/hci_ipc.conf 

Then I set west to use my board and sysbuild and try to build:

> west config build.board cc1medv1_nrf5340_cpuapp

> west config build.sysbuild True

> west build --build-dir cc1-med/build cc1-med --board cc1medv1_nrf5340_cpuapp --pristine -DBOARD_ROOT=%CD%

This got me cmake failing.

The DTS also seems to now fail (didn't with 2.6) with:

Now I'm stuck....I'll look at the DTS thing tomorrow... I think I already knew that the DTS stuff had changed 2.6 to 2.8... but the migration guide doesn't reference it as far as I can see?

[BrianW]

1st error: sysbuild.conf goes int he build target sub directory.

This generates many kconfig errors:

-  the DFU building part is now complex... remove for later

- the option noted int he migration guide SB_CONFIG_PM_MCUBOOT_PAD requires a hex value - but no explanation of what this option is for that I can find (both the nordic site and zephyr search options find no responses...). set to 0x200 as a likely value

- option SB_CONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH=y as noted in the migration guide is rejected as unknown

- and the option SB_CONFIG_NETCORE_HCI_IPC gets a warning, with a handy link that leads to a search page... that doesn't find that option..

And again, the CMake fails with a useless error that doesn't give any indication of what is causing the issue....

The kconfig warning that causes trhe mcuboot build to fail is for kconfig setting that are NOT in my sysbuid/mcuboot/prj.conf file :

How can I fix this?

[AHaug]

Hi,

I see you've started looking into this quite a bit since yesterday, but I'll start with breaking down the abstraction layer a bit w.r.t sysbuild and the change from using parent/child images. This level of understanding is most likely where you're already at, but I'm doing it to ensure we're on the same page.

In nRF Connect SDK we've previously used the child and parent-image system to manage multi-image builds such as for instance the nRF5340 which has both an image for the application core, for the network core (hci_rpmsg) and in most cases an image for a bootloader (mcuboot). To match what is used in Zephyr, the migration to sysbuild was done and thus in turn deprecating child and parent images in favour of companion images instead. I.e it is as good as the same, but different to comply with the norm in the Zephyr RTOS.

What you previously had within <your_project>/child_images/mcuboot.conf is now present within <your_project>/sysbuild/mcuboot.conf as shown in this sample: https://github.com/nrfconnect/sdk-zephyr/tree/main/samples/sysbuild/with_mcuboot/sysbuild and what you had in prj.conf that is related to adding multi-images is now within sysbuild.conf.

I created sysbuild.conf (at the root where I run west - is this right?),

Yes, this is correct. The second big thing is as you mention sysbuild.conf. Since the build system is changed to use sysbuild, it's now sysbuild that manages your multiple images, and it is within sysbuild.conf you need to add configurations to enable said additional images (such as MCUboot through SB_CONFIG_BOOTLOADER_MCUBOOT=y).

The third big thing that has happened is the migration from hardware model 1 to hardware model 2 (which you've referred to), and the third big thing is the sysbuild.conf

Next to your work from today:

It's a bit hard to separate build logs from questions, could you edit the 3 earliest replies to use "insert -> code" insert for whats from the build log and the rest outside?

Do you have SB_CONFIG_BOOTLOADER_MCUBOOT=y within sysbuild.conf or is it just within sysbuild/mcuboot.conf?

Kind regards,
Andreas

[BrianW]

Hi Andreas

Ok. Lets start with the migration to HWMv2. I have managed to rename/update my board files so that doing west boards can see the board, and that it manages to do the dtc part.

I have 3 issues I think here:

1/ warnings about depreciated labels

-- Found BOARD.dts: C:/work/dev/if-device-nrf53/boards/infrafon/cc2v1/cc2v1_nrf5340_cpuapp.dts
'label' is marked as deprecated in 'properties:' in C:/ncs/v2.8.0/zephyr/dts/bindings\audio\nordic,nrf-pdm.yaml for node /soc/peripheral@50000000/pdm@26000.
'label' is marked as deprecated in 'properties:' in C:/ncs/v2.8.0/zephyr/dts/bindings\i2s\nordic,nrf-i2s.yaml for node /soc/peripheral@50000000/i2s@28000.

I can ignore these, yes?

2/ a more serious looking warning, but related (as far as I can tell) to dts definitions in the SDK

-- Including generated dts.cmake file: C:/work/dev/if-device-nrf53/cc1-med/build/mcuboot/zephyr/dts.cmake
CMake Warning at C:/ncs/v2.8.0/zephyr/cmake/modules/dts.cmake:389 (message):
  dtc raised one or more warnings:

  <stdout>: Warning (avoid_unnecessary_addr_size):
  /soc/peripheral@50000000/i2s@28000: unnecessary #address-cells/#size-cells
  without "ranges" or child "reg" property

Call Stack (most recent call first):
  C:/ncs/v2.8.0/zephyr/cmake/modules/zephyr_default.cmake:133 (include)
  C:/ncs/v2.8.0/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:66 (include)
  C:/ncs/v2.8.0/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:92 (include_boilerplate)
  CMakeLists.txt:12 (find_package)

The dtsi file that defines the i2s reg and address-cells for the controller is in the SDK: file zephyr/dts/arm/noridc/nrf5340_cpuapp_peripherals.dtsi :

i2s0: i2s@28000 {

    compatible = "nordic,nrf-i2s";

    #address-cells = <1>;

    #size-cells = <0>;

    reg = <0x28000 0x1000>;

    interrupts = <40 NRF_DEFAULT_IRQ_PRIORITY>;

    status = "disabled";

};

 

My dts just enables it and adds pinctrl definition, as well as a gpio used for the sdmode of the amp.

&i2s0 {          

    status = "okay";

    compatible = "nordic,nrf-i2s";

    label="I2S audio out MAX98357A";

    pinctrl-0 = <&i2s0_default>;

    pinctrl-1 = <&i2s0_sleep>;

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

    i2s_sdmode: sdmode {

        compatible = "nordic,gpio-pins";

        gpios = <&gpio1 14 GPIO_ACTIVE_HIGH>;        // P1.14

    };

};

Is there a way for me to 'correct' the warning for the base definition?

3/ enabling the PDM driver 

My DTS has the PDM defined as:

&pdm0 {          

    status = "okay";

    compatible = "nordic,nrf-pdm";

    label="PDM micro in";

    pinctrl-0 = <&pdm0_default>;

    pinctrl-1 = <&pdm0_sleep>;

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

    pdm_en: en {

        compatible = "nordic,gpio-pins";

        gpios = <&ioexp0 12 GPIO_ACTIVE_HIGH>;        // GPB.04

    };

};

This doesn't cause an issue for the dtc, but I saw a problem for KConfig which didn't like having CONFIG_NRFX_PDM=y (which was ok for v2.6). Do I need to evolve something in the dts to allow me to define the CONFIG to include the PDM driver?

btw, I updated the nrf7002/wifi bits of the DTS, and it now accepts that the DTS has a valid wifi DT to let the wifi stuff in prj.conf be accepted.

thanks

 

[BrianW]

Now for sysbuild with mcuboot. btw, if I build without sysbuild (build.sysbuild=False), then the KConfig part gives some warnings buit gets further. With sysbuild, it breaks at the KConfig checking stage.

What you previously had within <your_project>/child_images/mcuboot.conf is now present within <your_project>/sysbuild/mcuboot.conf

Ok, I see the example has the file called mcuboot.conf, however if I name it that then I get:

CMake Error at C:/ncs/v2.8.0/zephyr/cmake/modules/extensions.cmake:2861 (message):
  No prj.conf file(s) was found in the
  C:/work/dev/if-device-nrf53/cc1-med/sysbuild/mcuboot folder(s), please read
  the Zephyr documentation on application development.

So I will name it prj.conf.

It seems it doesn't like something about the flash driver? But this worked fine in 2.6... and also I don't get this error if using child_images build system...

Note I have a pm_static.yml to define my partitions as I have an external flash chip also - does this make a difference? (again, all fine on 2.6)

[BrianW]

And, as I said, with the old childimage system it gets further thru the config process (does the CPUNET, and mcuboot, then gets (I assume) to app), and it stops with this:

I don't understand?

[BrianW]

after finding the fix for the CONFIG_FLASH for the sysbuild, it also stops at this step. Can you explain why, given it seems to be using all the elements from the correct toolchain?

Without a fix for this I am completely blocked.

Its failing to link a cmake tool?

The only other error I see is this:

but this seems to be linked to the nrf70 wifi stuff? Maybe no link to the cmake error?

I also see this:

warning: DISK_DRIVER_FLASH (defined at drivers/disk/Kconfig.flash:4) was assigned the value 'y' but
got the value 'n'. Check these unsatisfied dependencies: DT_HAS_ZEPHYR_FLASH_DISK_ENABLED (=n). 

which makes me wonder why it can't find the flash disk definition in my DTS? What exactly does the DT_HAS_... macro look for? I have defined 

        zephyr,flash-disk = &mx25r64;

Hi,

HWM2

BrianW said:

I can ignore these, yes?

I wouldn't recommend you to ignore any compilation warnings. The warnings you mention are labeled as deprecated.

BrianW said:

2/ a more serious looking warning, but related (as far as I can tell) to dts definitions in the SDK

This warning seems to be interesting as it is not present in the default audio application configuration (and in neither of the other samples I've built to test). Could you add your modification to the i2s0 device within for instance https://github.com/nrfconnect/sdk-nrf/tree/main/applications/nrf5340_audio or any of the other audio samples and see if you're able to force the warning w.r.t address and size from there?

BrianW said:

3/ enabling the PDM driver 

Looks to me that this has changed from _PDM to _PDM0 in 2.8.0: https://docs.nordicsemi.com/bundle/ncs-2.8.0/page/kconfig/index.html#CONFIG_NRFX_PDM0

Sysbuild:

I see you've addressed some of the sysbuild questions/uncertainties in the reply following the longer set of sysbuild questions so I'll start there:

BrianW said:

I'm thinking that with sysbuild the 'main app' prj.conf is NOT merged in with the mcuboot one, so this has to stand on its own?

Yes, this is correct. You still need to have a prj.conf for your app. Sysbuild only handles companion images

BrianW said:

Ok, I see the example has the file called mcuboot.conf, however if I name it that then I get:

You can see the structure of sysbuild companion images here as well: https://github.com/nrfconnect/sdk-nrf/tree/main/applications/nrf5340_audio/sysbuild. I'm not sure if my explanation of the structure caused any misunderstandings.

It is unfortunately too many changes simultaneously that causes the build crashes with no useful information you listed in your replies from yesterday.

Here's a breakdown of what I would've done if I were to migrate from 2.6.1 to 2.8.0:

1. Start with the audio app and montior changes from 2.6.1 to 2.8.0. Pay attention to changes from child_image/ to sysbuild/ as well as the addition to sysbuild.conf together with prj.conf
2. Compare the board files within said project and the board files for the 5340 in 2.6.1 and 2.8.0. These are the changes w.r.t hwm1 and hwm2 in addition to the migration note for this https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_hwmv2.html
3. After you've migrated to hwmv2, try to build with "--no-sysbuild". This should allow you to build with child and parent images. This is still supported in 2.8.0, but will not be in 2.9.0.
4. Resolve any configuration errors and make it compile without sysbuild
5. Start with migration from child/parent images to sysbuild. Make note of the changes in item 1 and the two links you sent in the start
   

   https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_sysbuild.html

   https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_guide_2.8.html

Unfortunately there will be some downtime in the coming weeks due to holidays here in Norway, so activity will be slow on devzone until early Janaury. I'm sorry for not being able to help you pinpoint the migration issues before now but I strongly believe that if you methodically follow the 5 steps I listed you will succeed.

Kind regards,
Andreas

Two more notes:

See https://github.com/nrfconnect/sdk-zephyr/blob/7f8d857bf1f57b07e832d52263beaa23c91fef24/boards/nordic/nrf5340_audio_dk/nrf5340_audio_dk_nrf5340_cpuapp_common.dtsi#L122 w.r.t i2s0 device and how it is set up for the audio dk and https://stackoverflow.com/questions/21871362/how-to-put-comments-in-device-tree-source-files#21892052 w.r.t commenting out lines in dts (which is present within our dts files. Interesting...)

Edit: Never mind the commenting, it is a syntax in dts: https://www.kernel.org/doc/Documentation/devicetree/booting-without-of.txt

Kind regards,
Andreas

[BrianW]

thanks for the info above. Its true the jump 2.6->2.7/2.8 is very hard, especially due to the zephyr updates, and lacking a set of detailled release notes that show exactly what is been deleted/updated/added doesn't help. 

My strategy since yesterday is that I have started with the wifi/sta sample prj.conf (which doesn't build completely but gets past the config step to actually compile source files), and worked forwards from that... somehow this has resolved the CMake ld error, but I have no idea why.

I hope to get the non-sysbuild working first as ou suggest, but I'm still stuck with a couple of issues

1 points quickly (I hope)

USB FAT32 flash disk operation

warning: DISK_DRIVER_FLASH (defined at drivers/disk/Kconfig.flash:4) was assigned the value 'y' but
got the value 'n'. Check these unsatisfied dependencies: DT_HAS_ZEPHYR_FLASH_DISK_ENABLED (=n). See
docs.zephyrproject.org/.../kconfig.html and/or look up
DISK_DRIVER_FLASH in the menuconfig/guiconfig interface. The Application Development Primer, Setting
Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful
too.

which leads to:

CMake Warning at C:/ncs/v2.8.0/zephyr/CMakeLists.txt:952 (message):
No SOURCES given to Zephyr library: drivers__disk

Excluding target from build.

What is required to satisfy DT_HAS_ZEPHYR_FLASH_DISK_ENABLED  ? (again, this is a change from 2.6)? I have tried the usb disk example from 2.8, but can't work out what the key difference is between the dts files?

thanx
