Custom nRF5340 Board in NCS

Hello Conner,

I assumed this was somewhat taken care of in this case so I haven't looked into it further unfortunately. As this case is a bit old it might be preferable to create a new one. Though have a look at this webinar about this very topic coming out on Wednesday. It might be it will answer all your questions about it.

I wanted to see if there has been any progress on this? My current solution is still to do what @MartKano recommended below, and simply add an empty block.

This problem seems to be that after creating a new board of type nrf5340_cpuapp (nonsecure), there is an out-of-the-box issue with the device tree labeling.

I've got the same compilation error. I add some lines to define sram0_shared and now it complies:

/ {
	model = "XX";
	compatible = "XX,XX-v1-0-0";

    chosen {
        zephyr,sram = &sram0;
        zephyr,flash = &flash0;
        zephyr,code-partition = &slot0_partition;
        zephyr,ipc_shm = &sram0_shared; 
    };
	
    reserved-memory {
        #address-cells = <1>;
        #size-cells = <1>;
        ranges;


        //sram0_ns: image_ns@20000000 {
            /* Non-Secure image memory */
        //};
        sram0_shared: memory@20070000 {
            /* SRAM allocated to shared memory */
            reg = <0x20070000 0x10000>;
        };
    };
};

Hope that's helped.

Hehe yeah likewise.

[quote user="WesC"]

but i changed my environment to just use NCS 1.9.1 and Toolchain 1.9.1

[/quote]

Gotya. From the log it looks like that didn't get updated completely.

[quote user="WesC"]

if i make no modifications to the custom generated DTS file it will not compile because there are DT nodes with Aliases that are used in main.c

[/quote]

You can for instance run the button example on a custom 52840 board by copying contents of the nrf52840dk dts file. And you can run hello world on a default custom 5340 board. Getting the alias in the nrf5340 dts etc however is a bit more complex, as there are several files that needs to be renamed and modified.

I believe this guide by Simon mentions everything you need to know though (see section 2.2), as well as what the different files are for. I just tried it myself along with the button example, and the build works fine. I haven't tried it in NCS 2.0 yet though.

Do the steps mentioned in the guide work for you?

So I moved to NCS V2.0.0

I started by creating a new board and locating the board directory outside of NCS. I then added some elements of the nrf5340_cpuapp_common_ns.dts to my Custom5340_cpuapp_ns.dts. I have attached my custom dts for reference. Here is the error I get.

RE: Custom nRF5340 Board in NCS

WesC — Thu, 02 Jun 2022 12:25:25 GMT

Sorry for the delay I was working on other things.

So I was working on Main with NCS 1.9.1 toolchain for LE Audio.

but i changed my environment to just use NCS 1.9.1 and Toolchain 1.9.1

my custom board directory is created outside of NCS folder

I was using zephyr/samples/basic/button and created a custom nRF5340_cpuapp_ns board.

if i make no modifications to the custom generated DTS file it will not compile because there are DT nodes with Aliases that are used in main.c

if i look at the nRF5340_cpuapp_common.dts and copy elements of that dts into the custom board that have the button nodes and aliases, i get many more error of the type

C:\Users\Wes\ncs\v1.9.1\zephyr\include\toolchain\gcc.h:61:36: error: static assertion failed: ""
61 | #define BUILD_ASSERT(EXPR, MSG...) _Static_assert(EXPR, "" MSG)

also i get this

CMake Warning at C:\Users\Wes\ncs\v1.9.1\zephyr\cmake\app\boilerplate.cmake:241 (message):
BOARD_ROOT element without a 'boards' subdirectory:

c:/Users/Wes/Documents/Nordic/MyProjects/fund_less2_exer2_solution

Hints:

- if your board directory is '/foo/bar/boards/<ARCH>/my_board' then add '/foo/bar' to BOARD_ROOT, not the entire board directory
- if in doubt, use absolute paths

Do i need to modify the boilerplate to look for custom boards in the other directory?

looking for advice to create a custom board

First of all, it seems to me that you are running the Master branch SDK along with the NCS 1.9.1 toolchain. Is this on purpose?

> BOARD_ROOT element without a 'boards' subdirectory

This also gives the impression that you might have saved the board to another directory, or modified the BOARD_ROOT.

Are you able to build a basic hello world sample with a new default 5340 board? (ie. nothing added besides what comes with its creation in VSC).

i cannot get it to build. So what i did was create a new board and selsct the nRF5340_cpuapp_ns as the base. I then copied what i thought i would need from the nRF5340_cpuapp_common.dts into my test5340.dts. when i compile i get the following error about a DTS error with sram0_sherd

Hey Wes,

Unfortunately, I will have to get back to you next week.

[quote user=""] I have tried using VSC with the nRF5340 and have been unsuccessful[/quote]

What issues are you running into? Is bt_ready() not returning like in this case, or are you not able to build a project with a custom board?

Regards,

Elfving
