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
SB_CONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH=y
SB_CONFIG_MCUBOOT_GENERATE_UNSIGNED_IMAGE=y

SB_CONFIG_NETCORE_HCI_IPC=y
SB_CONFIG_NETCORE_APP_UPDATE=y
SB_CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256=y

#CONFIG_MCUBOOT_SIGNATURE_KEY_FILE="/work/dev/if-device-nrf53/keys/bootloader_priv-ecdsa256.pem"

SB_CONFIG_MCUBOOT_BOOTLOADER_MODE_SWAP_WITHOUT_SCRATCH=y

# nrf7002 firmware handled by sysbuild
SB_CONFIG_WIFI_NRF70=y
SB_CONFIG_WIFI_NRF70_SYSTEM_MODE=y
#SB_CONFIG_WIFI_PATCHES_EXT_FLASH_XIP=y     later

# build of dfu packages
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_BUILD=y
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_APP=y
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_NET=y
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_WIFI_FW_PATCH=y

SB_CONFIG_DFU_ZIP=y
SB_CONFIG_DFU_ZIP_APP=y
SB_CONFIG_DFU_ZIP_NET=y
SB_CONFIG_DFU_ZIP_WIFI_FW_PATCH=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....

What is not correctly installed here?

[BrianW]

This error is caused by my board not being migrated to HWMv2 (despite the migration guide here https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_hwmv2.html explicitly stating that OOT boards do not need to be migrated....)

Once the board is fixed up  to HWMv2, and the build command references the board as board/soc/variant instead of borad_soc_variant (thanks a lot for a meaningless change...) the 'sta' sample gets a lot further (it now has dependances on LEDs in the DTS it seems)

I also had to update my MCP23017 DTS reference to be compatible="microchip,mcp23017" instead of mcp23xxx to let the DTS compile (why? don't know) for this error:

devicetree error: gpio controller <Node /soc/peripheral@50000000/i2c@9000/mcp23017@20 in 'C:/ncs/v2.8.0/zephyr/misc/empty_file.c'> for <Node /soc/peripheral@50000000/pdm@26000/en in 'C:/ncs/v2.8.0/zephyr/misc/empty_file.c'> lacks binding

Now its:

    ioexp0: mcp23017@20 {

        status = "okay";

        compatible = "microchip,mcp23017";

        reg = < 0x20 >;

        gpio-controller;

        ngpios = < 16 >;

        #gpio-cells = < 2 >;

        int-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;        // P1.15 interupt from ioexpander

    };

in case anyone else gets stuck at this one...

My application build is still broken, due to 'KConfig warnings'. Pity it doesnt say which ones:

[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

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

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:

After diving into a maze of nasty twisty little KConfig dependancies, it seems this is because I need CONFIG_FLASH=y in the sysbuild/mcuboot/prj.conf. Previously this was configured just in the main prj.conf for the project.

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?
