S32k314 Timer

Dear All,

Hello, I using S32k314 board (RTD3.0.0), but i have a question about STM in GPT module.

According to S32k3xx RM.pdf,  I found S32k314 allowed 2 instances of STM, STM_0 and STM_1 .

But, S32k314 don't have a clock about STM_1 in example code at design studio 3.5 version.

I wonder "S32K314 also supports STM_1, but why is there no clock configuration for STM_1 in the example code?"

Thanks.

Thank you for your reply.

I tested adding the STM1 module, but the S32k314 board doesn’t boot properly when it runs GPT Init.

After looking into it, I found out that the S32K314 doesn’t actually have a clock for STM1.

As a result, after removing STM1,  the S32k314 board boot normally,

It operation doesn’t match what’s described in the S32k3xx reference manual.

Hello,

Ok, but once you configure clock you also have to enable it to the peripheral.

Did you enabled it in ME module for STM0 and 1?

It is in MCU plugin:

I have tested it here and everything is running as expected:

Attached is the example file if you like to test it

Best regards,

Peter

Hello,

Example code usually implement only basic demo features to show the functionality.

I wonder "S32K314 also supports STM_1, but why is there no clock configuration for STM_1 in the example code?"

I have just open the example for GPT and simply added STM0 and 1 modules and everything works as expected. Both are supported.

Simply follow the example or screenshot above and add STM1.

Best regards,

Peter
