https://devzone.nordicsemi.com/f/nordic-q-a/89959/how-to-debug-undefined-reference-to-__device_dts_ord_xx-errorsHi! Currently, I&#39;m trying to create a new board. I have a source code for the Thingy52 board and the code just compiles. With my own board I get __device_dts_ord_10 linker errors. And I don&#39;t know, why. I have no idea how to debug such errors sinceen-USTelligent Community 13Thu, 11 Aug 2022 11:50:43 GMThttps://devzone.nordicsemi.com/thread/381182?ContentTypeID=1Thu, 11 Aug 2022 11:50:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:709c9d6f-b837-44d6-ba0a-f4add7a905b9Einarh<p>Hi</p> <p>I can&#39;t immediately see anything wrong with this devicetree.</p> <p>Are you still having this issue? have you made any progress?</p> <p>Did the thread with the similar issue give you any leads?</p> <p>-Einar</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/378378?ContentTypeID=1Fri, 22 Jul 2022 19:14:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7e8af97e-2507-41b1-be8b-e02eb7c29cc1who9vy<p>Here is the zephyr.dts of the build directory</p> <p><pre class="ui-code" data-mode="text">/dts-v1/;

As I noted, the code does work with the Thingy52 (and with the nrf52 DK). There is one further difference. The board I created is based on the nRF52810 and the others on the nRF52832. But why these errors appear? And is there a guide how to debug such errors?</p> <p>The static const struct gpio_dt_spec led is from the esb_ptx example (<a id="" href="https://github.com/nrfconnect/sdk-nrf/blob/main/samples/esb/ptx/src/main.c">https://github.com/nrfconnect/sdk-nrf/blob/main/samples/esb/ptx/src/main.c</a>). Since I only use one LED, I removed the other 3 of them.</p> <p>The dts part of my question is from the board dts file. Here is the complete file:</p> <p></p> <p><code>/dts-v1/; #include &lt;nordic/nrf52810_qfaa.dtsi&gt; / { model = &quot;XXX&quot;; compatible = &quot;xxx,example&quot;; chosen { zephyr,sram = &amp;sram0; zephyr,flash = &amp;flash0; zephyr,code-partition = &amp;slot0_partition; }; aliases { led0 = &amp;led0; sw0 = &amp;button0; }; leds { compatible = &quot;gpio-leds&quot;; led0: led_0 { gpios = &lt;&amp;gpio0 7 GPIO_ACTIVE_LOW&gt;; label = &quot;Red LED&quot;; }; }; buttons { compatible = &quot;gpio-keys&quot;; button0: button_0 { gpios = &lt;&amp;gpio0 11 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)&gt;; label = &quot;Button&quot;; }; }; }; &amp;gpio0 { status = &quot;okay&quot;; }; &amp;flash0 { partitions { compatible = &quot;fixed-partitions&quot;; #address-cells = ; #size-cells = ; boot_partition: partition@0 { label = &quot;mcuboot&quot;; reg = ; }; slot0_partition: partition@c000 { label = &quot;image-0&quot;; reg = ; }; slot1_partition: partition@16000 { label = &quot;image-1&quot;; reg = ; }; scratch_partition: partition@20000 { label = &quot;image-scratch&quot;; reg = ; }; storage_partition: partition@2a000 { label = &quot;storage&quot;; reg = ; }; }; }; </code></p> <p></p> <p>Here is the error message:</p> <p><code>[146/157] Linking C static library app/libapp.a<br />[147/157] Linking C executable zephyr/zephyr_pre0.elf<br />FAILED: zephyr/zephyr_pre0.elf zephyr/zephyr_pre0.map <br />: &amp;&amp; ccache /opt/nordic/ncs/toolchains/v2.0.0/opt/zephyr-sdk/arm-zephyr-eabi/bin/arm-zephyr-eabi-gcc zephyr/CMakeFiles/zephyr_pre0.dir/misc/empty_file.c.obj -o zephyr/zephyr_pre0.elf -fuse-ld=bfd -Wl,-T zephyr/linker_zephyr_pre0.cmd -Wl,-Map=xxx/build/zephyr/zephyr_pre0.map -Wl,--whole-archive app/libapp.a zephyr/libzephyr.a zephyr/arch/common/libarch__common.a zephyr/arch/arch/arm/core/aarch32/libarch__arm__core__aarch32.a zephyr/arch/arch/arm/core/aarch32/cortex_m/libarch__arm__core__aarch32__cortex_m.a zephyr/arch/arch/arm/core/aarch32/mpu/libarch__arm__core__aarch32__mpu.a zephyr/lib/libc/minimal/liblib__libc__minimal.a zephyr/lib/posix/liblib__posix.a zephyr/soc/arm/common/cortex_m/libsoc__arm__common__cortex_m.a zephyr/soc/arm/nordic_nrf/nrf52/libsoc__arm__nordic_nrf__nrf52.a zephyr/drivers/clock_control/libdrivers__clock_control.a zephyr/drivers/console/libdrivers__console.a zephyr/drivers/timer/libdrivers__timer.a modules/nrf/lib/fatal_error/lib..__nrf__lib__fatal_error.a modules/nrf/subsys/esb/lib..__nrf__subsys__esb.a modules/hal_nordic/nrfx/libmodules__hal_nordic__nrfx.a modules/segger/libmodules__segger.a -Wl,--no-whole-archive zephyr/kernel/libkernel.a zephyr/CMakeFiles/offsets.dir/./arch/arm/core/offsets/offsets.c.obj -L&quot;/opt/nordic/ncs/toolchains/v2.0.0/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/thumb/v7e-m/nofp&quot; -Lxxx/build/zephyr -lgcc zephyr/arch/common/libisr_tables.a -no-pie -mcpu=cortex-m4 -mthumb -mabi=aapcs -mfp16-format=ieee -Wl,--gc-sections -Wl,--build-id=none -Wl,--sort-common=descending -Wl,--sort-section=alignment -Wl,-u,_OffsetAbsSyms -Wl,-u,_ConfigAbsSyms -nostdlib -static -Wl,-X -Wl,-N -Wl,--orphan-handling=warn &amp;&amp; cd xxx/build/zephyr &amp;&amp; /opt/nordic/ncs/toolchains/v2.0.0/Cellar/cmake/3.20.5/bin/cmake -E echo<br />/opt/nordic/ncs/toolchains/v2.0.0/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.bfd: app/libapp.a(main.c.obj): in function `button_pressed&#39;:<br />xxx/src/main.c:179: undefined reference to `__device_dts_ord_10&#39;<br />/opt/nordic/ncs/toolchains/v2.0.0/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.bfd: app/libapp.a(main.c.obj): in function `main&#39;:<br />xxx/src/main.c:254: undefined reference to `__device_dts_ord_10&#39;<br />collect2: error: ld returned 1 exit status<br />ninja: build stopped: subcommand failed.<br />FATAL ERROR: command exited with status 1: /opt/nordic/ncs/toolchains/v2.0.0/bin/cmake --build xxx/build<br /><br /></code></p> <p>That is the error message. <strong>Fun fact:</strong> The second error at line 254 cannot happen there because there is no line 254 in main.c.
