to check the issue. Re: RTC example can't build successfully in frdm_mcxw72 board Hi RomanVR, The example: zephyr/samples/drivers/counter/alarm worked well, but the RTC example still have problem during build even i created the overlay file the same as the snapshot. anliu114036_0-1784094520929.png below is the key error message during the build process, it should be the hint to solve the issue under your help. many thanks!

The current implementation of the RTC driver of MCXW72 is meant to be used with the counter.h Zephyr library. Considering this, I'd suggest testing RTC functionality with the example: zephyr/samples/drivers/counter/alarm. As shown in the image below:
RomanVR_0-1784070722139.png
This project template will configure the RTC as a counter with an alarm functionality. To test it, please create in the /boards folder an overlay file [frdm_mcxw72.overlay] and add the following contents to the file:
/ {
aliases {
rtc=&rtc;
};
};
&rtc{
status = "okay";
counter_rtc: counter_rtc {
status = "okay";
};
};
Please let me know if these modifications help on your development. Re: RTC example can't build successfully in frdm_mcxw72 board Hello @anliu114036,
For the RTC example to build properly you have to add the following setting to your prj.conf file:
CONFIG_RTC_INIT_PRIORITY=70
Please let me know if this works for you. Re: RTC example can't build successfully in frdm_mcxw72 board Hi RomanVR, i did add the prj.conf file with the setting CONFIG_RTC_INIT_PRIORITY=70 anliu114036_0-1784163152280.png but it still can't pass the building, and the error prompt message is the same, you can find the whole build log in the attachment. hope it can help to find the issue point. Best regards! Re: RTC example can't build successfully in frdm_mcxw72 board Hi @anliu114036,
Would you please add the setting inside the file named prj.conf? As adding it in the created file named as frdm_mcxw72.conf will not be fetched automatically by the Zephyr build system like it does for an overlay file.
RomanVR_0-1784217266337.png
Please let me know if this helps. Re: RTC example can't build successfully in frdm_mcxw72 board Hi RomanVR, it worked after add the setting in the prj.conf, thanks for your help! but there is still a problem that after i flashed the image into the evk, the RTC function looks still broken, because the time information is keep the same from the print message anliu114036_0-1784258576109.png can you help check it, many thanks! Re: RTC example can't build successfully in frdm_mcxw72 board Hi @anliu114036, glad to know you got the example built properly.
Regarding the RTC functionality, currently, the RTC driver from Zephyr (rtc.h) is not compatible with our lower-level driver used for the MCXW72 RTC node (counter_mcux_rtc.c), the usage of the W72's RTC should be through the counter.h driver as the APIs are compatible with the defined in the lower-level driver.
The alarm example I shared before (zephyr/samples/drivers/counter/alarm) demonstrates the full current functionality of our RTC driver.
Please let me know if this information clears out your doubts.
