Driver IP for CLOCKOUT configuration

[DirkEtzler]

When using RTD PlatformSDK_S32ZE_S32Z270_R52_0_0 version 2.0.1 are there driver IP functions to set the multiplexer and dividers in GPR and MC_CGM registers to configure the CLKOUT_x functionalities?  (E.g., what clock source to bring out and what divider value to use.)  Or do I need to write them myself?

Hello @DirkEtzler,

Thanks for reaching out to us. It is possible to configure the configuration for the CLKOUT_X, I am going to use CLKOUT_2 as an example. First I started a project from the Dio example and added the clock driver:

Now go to the clock configuration tool and scroll down and search for CLKOUT_2, you can also select it in the dropdown list as in the image:

Double click on the MUX symbol and select P4_CLK_SRC_CLK:

Now you can select the source by scrolling down to 

Again, double click on the MUX symbol and select the source you want to use:

After that, several errors may appear in the clocks and peripeharls view, most of them can be corrected by right clicking on them and using the suggested solution:

For the one that cannot be solved like that, double click on the error and match the configuration you did in the clocks view now in the peripherals view:

Let me know if you were able to solve the problem with these steps above.

Hello @alejandro_e,

following your guidance below, I have been able to configure the corresponding multiplexer and dividers using the S32DS clock configuration tool.  Checking the registers after initialization show correct values of all involved registers and also the correct frequency at the CLOCKOUTx outputs.

Thank you for your assistance.
