How to configure clock for TCM on S32K3x?

Chris-Sun — Fri, 12 Apr 2024 08:10:16 GMT

I am currently using the TCM feature of S32K3x in my RTD.

I encountered an issue while configuring the TCM clock:

According to the source code of RTD, it is necessary to configure a macro definition, CLOCK_IP_HAS_TCM_CM7_0_CLK, before configuring the TCM clock.

However, there is currently no corresponding place for CLOCK_IP_HAS_TCM_CM7_0_CLK.

I also couldn't find any configuration options for the TCM clock in S32DS software.

Should I manually modify Clock_Ip_Cfg_Defines.h to add this configuration?

(I'm using S32K312 Project)

The version information:

S32DS: 3.5

RTD: S32K3_RTD_3_0_0_D2303_ASR_REL_4_7_REV_0000_20230331

Best regards,
Chris

Hi @Chris-Sun

The PRTN2_COFB1_CLKEN[REQ62] field for Cortex-M7_0 is enabled at reset as you can see from the image below:

Hi Mr.Sun:

------

From your appeal description, I cannot infer a solution to the problem. At present, K312 does not seem to support the enable configuration of TCM-CM7_0_CLK. Can you provide a more detailed solution.

The problem I am currently facing is that after the interrupt is enabled and triggered, I cannot enter the interrupt. I don't know if it is related to TCM-CM7_0_CLK not being enabled?
