Unable to use an RTC example - source files missing in KDS 3.0

[piotrcerba]

Hello, I am willing to implement RTC based on the example app from Kinetis SDK 1.2.0 for KL43.

I added following folders as the header files source, they are the same as the ones for the RTC example (and a couple more):

Header files are successfully recognized, however, I am missing the source files connected to them. For example fsl_rtc_driver.h has the bool RTC_DRV_IsAlarmPending(uint32_t instance); function prototype. It is obvious that its body is present in fsl_rtc_driver.c which is in the folder I also included into project settings. Unfortunately it does not see any of the .c files, even though they are correctly seen in the project tree:

Compiler gives following errors:

Since the path with required .c source files is correctly added - I don't know what am I missing.

There must be some non-manual way to fix this problem. How to do it?

Hello ,

Have you build the KSDK platform library ? Please refer to here :

Freescale\KSDK_1.2.0\doc\Getting Started with Kinetis SDK (KSDK) v.1.2.pdf\5.3 Build the platform library .

Hope it helps

Yes, I have built the platform library right after installing SDK a couple of weeks ago.

EDIT: Of course - the example project with RTC compiles fine and works perfectly on UART.

Hello Piotr Cerba:

Each of the example projects have the KSDK platform library linked. You have built the library but most probably you are missing the step of linking the generated library object file to your project. You can do this from Project -> Properties -> C/C++ Build -> Settings -> Cross ARM C Linker -> Other objects.

To avoid this kind of issue and since you are starting with KSDK then I recommend you to follow the next guide, which will help you understand how to create KSDK projects from scratch in KDS:

If any issues arise just let us know.
