SDK 3.0.0 custom board definition

I'm having trouble porting my project from the older SDK (2.6.0) to the new SDK. 

I thought the most straightforward way to do that would be to start with a sample project similar to what I want to do. So I took the Matter Window Cover Sample. I have the nRF54L15-DK so I compiled the project for that board and it seems to work.

Now I use the VSCode button to create a new board. After closing VSCode and opening it again I can select my new custom board as the target for the build. It fails as my custom board is pretty much just boilerplate empty board definitions. So I start copying the contents of the nRF54L15-DK board definitions to my own custom board folder. The aim being to get the project to compile for the same dev kit with my custom board as the target. Ideally I would make no changes to the files but due to custom name I still have to do that. This also means I have to make another partition manager static definition file. I just copy the one used for the DK build and rename it for my custom board.

After fighting with some very hard to fix devicetree errors I get compilation process to reach the partition manager stage and there is something weird happening there. I have the exact same contents for the static definition file as the DK but for my board the build fails complaining about too many gaps in the partitions. I'm attaching the actual file I use for this.

pm_static_blindy_v3_nrf54l15_cpuapp.zip

The error I get from partition manager is this:

-- Found partition manager static configuration : /home/tiit/code/nordic/blindy_matter/pm_static_blindy_v3_nrf54l15_cpuapp.yml

Gaps found (2):0xd800-0x165000 0x17d000-0x172000 The most common solution to this problem is to fill the smallest of these gaps with statically defined partition(s) until there is only one gap left. Alternatively re-order the already defined static partitions so that only one gap remains.

Can you please check what I'm doing wrong here to cause this. This is somehow caused by using the custom board definition. I'm also attaching the whole custom board folder here just in case you can see something weird in there. This is just the folder that has to be extracted into the boards folder and after a VSCode restart it appears as a target for the build.

  • Hello Tiit,

    A couple of starting points here before I get back to you early in the coming week,

    1. You state that you've based your project on the Matter window cover sample, is this from 2.6.0 or is it from a newer version of NCS (if so which version are you referring to with "to the new SDK"?  Nonetheless, there will be quite a few changes between 2.6.0 and 2.9.1 or 3.0.0 (of those are the versions you're referring to), so we'll just go through the hoops until we get there.

    2. The first thing I would like you to verify is the hardware model you're using. Since you're based on 2.6.0 I assume it is hwm2, but could you verify if you've gone through the steps here? https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_hwmv2.html 

    3. The next is, which revision of the nRF54L15 SoC are you using? I.e what I'm asking is if your SoC revision is compatible with the SDK version you intend to use

      • I just copy the one used for the DK build and rename it for my custom board.
      I would say that this is the way to go, unless there are certain things that are set up in the nrf54l15Dk's board files that you've not attached somehow. Could you verify if you've done the following:
      1. Build the window cover sample for the nrf54l15dk
      2. Checked the generated partitions.yml located within build (or build/your_app/ or build/your_app/zephyr I can't quite remember, but there should only be one)
      3. Copy the contents of that and attach in a static partitioning file that your custom board will use
    4. Since you're migrating from child/parent images used in NCS 2.6.0 I would also recommend you to have a look at the sysbuild academy lesson unless you've already done so: https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-sysbuild/topic/sysbuild-explained/ 

    Let me know about this and I'll get back to you when I get back in office next week

    Kind regards,
    Andreas

  • Hi Andreas,

    Thank you for getting back to me so fast and sorry I wasn't able to respond sooner.

    1. I used VSCode to install SDK 3.0.0 and created a new application from the example included with that (using the built in button for that). I changed nothing in that example and built it for my nRF54L15-DK. This worked and I was able to flash and add the device to Alexa through the Echo with Matter support (it did complain about the device not being certified but that is normal as I understand).

    2. My original code is based on SDK 2.5.0 with some changes it does work with 2.6.0 and that is what I have been using to develop the Matter branch of our firmware. There are still issues with that but the Matter build itself works and can also be added to most Matter controllers with the warning about certification. I spent two days trying to port that to SDK 3.0.0 without luck. So in frustration I decided to just take the clean example from 3.0.0 and get that example to build on my custom board as a starting point. I have a button and an RGB led on my board so the example should be very close to compatible. I also have the exact same external memory chip and had experience with doing a similar thing when we first started our firmware on 2.5.0. Now I'm guessing the hardware model thing should be correct when I start from the example in 3.0.0. SO what I want to do first is take the code that is working on the dev board and get this to compile on a custom board that still describes the exact same dev board. I'm not sure if I'm explaining this right. What I want to do is compile the clean example code but instead of selecting "nrf54l15dk/nrf54l15/cpuapp" I want to select "blindy_v3/nrf54l15/cpuapp". I clicked create new board and named it "blindy_v3". This created the board and I can select it as the target. But this fails because the board created is pretty much empty. Now I tried copying in all the required things from the SDK folders that defined the devkit but it still fails to build.

    3. I think my dev kit has the engineering sample. The markings on the chip say QFAABB. The sticker on the dev kit says PCA10156, 0.9.1, 2024.44

    The example does build and it does generate the partitions.yml file. But there is already a static partition file that is defined for each board in the project folder and I copied the one for the DK with no changes and I can see in the build process that the correct file does get included (Found partition manager static configuration :/home/tiit/code/nordic/blindy_matter/pm_static_blindy_v3_nrf54l15_cpuapp.yml). Should I just replace that with the one from the successful DK build? If so - why would it not work with the copy that works for the DK build? I would feel hesitant using this in production without understanding the reason for the problem.

    4. I will definitely take a look. I did use sysbuild for the Matter version already but I don't really understand it. I just know that whenever I make a build configuration I have to select sysbuild or things will fail in weird and interesting ways.

    Thank you for elaborating

    All here sounds good to me

    From 2.5 to 3.0 there are several significant changes in the SDK, including Matter, so yeah.. I understand the struggle when doing such a big leap.

    Tiit said:

    Correct, the default from 2.7.0 and is Hwm2.

    I'm following.

    I think this topic in our academy pages might be exactly what we need: https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-3-adding-custom-board-support/. Could you have a look through here and see if there's something you've missed when creating the files for your custom board based on the DK?

    That should be within the supported devices, so the issue you're seeing should not be due to the revision not being too old.

    Tiit said:

    I would recommend this as a starting point to verify that it works with that memory layout and then move to something more custom for your use case and your custom board in case required

    Tiit said:

    Could you clarify one thing for me; what would not work with the copy for the successfull DK build? There are a few versions up in the air at this point in our discussion. For instance

    • Custom board with sample from 3.0.0 with overlay from DK built successfully with 3.0.0
    • Custom board with sample from 2.5.0 ported to 3.0.0 with overlay from DK built successfully with 3.0.0
    • Custom board with sample from 3.0.0 with overlay from DK built successfully from 2.5.0
    • other?

    It should make more sense soon, hopefully. The course explains the difference between child/parent images and sysbuild quite well in my opinion, but if you have any follow ups from the sysbuild topic I'm more than happy to discuss them.

    Kind regards,
    Andreas

  • Hi Andreas,

    I looked at the linked linked academy guide and it seems I did pretty much exactly what is recommended there. And while I was working on that I did get a lot of devicetree errors until I reached my current state where I'm now stuck. Since the board I have defined for now is pretty much just SDK definitions copied into the custom board files I can safely share that here publicly.

    2210.soma.zip

    Maybe you can see what is happening with that. To try that all you have to do is unpack this into the boards folder of the Matter Window Cover sample and add the pm_static file from my first post to the root folder of the sample. 

    At the moment I'm not worrying at all about sysbuild or child/parent images. All I wan tot do is take the clean example from SDK 3.0.0 and compile that with toolchain 3.0.0. Instead of selecting the nRF54L15-DK as the target board I want to be able to select a board named "blindy_v3". The custom board definition can just be a copy of the dev board. I want to do that to have a starting point for changing the board into my actual custom board. That is the way I did that once before and it went kind of smoothly.

    I spent all day yesterday with another person from your support team coming to the conclusion that there is something wrong with SDK/toolchain 2.7.0 specifically that breaks when any newer versions are installed on Linux. So I seem to be in a really unfortunate position where I think I basically have to take the clean example from 3.0.0 and just port all of the business logic of my application over manually. I guess having a clean start can't really hurt. But for some reason I'm stuck getting the very first step of the custom board to working on the dev board. I hope you can take a look at the custom board I have attached here and let me know why this is happening.
