Hi, I tried to migrate my project from nRF Connect SDK v2.5.3 to v2.9.0, switching to sysbuild and creating my own board definition instead of using a overlay file.
I decided to go for v2.9.0 because I used this version for another project already and I have made the local changes in the SDK directory for correct netcore updates already.
I'm using the mcp2515 CAN controller which worked fine with SDK v2.5.3. But if I try to put the configuration into my new board definition, I get the following error message during the build process:

What could be the reason? I correctly defined the SPI interface and I set the chosen information. But the error message says that something is wrong with the device IDs... sounds like my devicetree entry is removed again during the build process...
&spi4 {
status = "okay";
pinctrl-0 = <&spi4_default>;
pinctrl-1 = <&spi4_sleep>;
pinctrl-names = "default", "sleep";
cs-gpios = <&gpio1 1 GPIO_ACTIVE_LOW>;
my_can: can@0 {
compatible = "microchip,mcp2515";
spi-max-frequency = <8000000>;
int-gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
status = "okay";
reg = <0x0>;
osc-freq = <24000000>;
bitrate = <1000000>;
//sjw = <1>;
sample-point = <875>;
};
};
[...]
/ {
chosen {
zephyr,canbus = &my_can;
};
};
The CAN configuration is enabled in prj.conf, not in the board definition. I hope this is okay, as there may be software that doesn't use the CAN.
Any ideas what is going wrong here?
Best regards,
Michael
