CAN configuration for s32K324

LavanyaR — Fri, 15 Dec 2023 11:47:56 GMT

Hi,

Here we are working in s32k324. We tried s32k312 CAN example code configuration into s32k324. But it is not working. If you CAN driver code for s32k324 means kindly share it to us.

Thank you in advance

Hi @LavanyaR

Sorry for the inconvenience this might cause.

We do not have an example for S32K324, but you can use the available ones for S32K344 devices (included with the RTDs).

Example S32K344 FlexCAN_Ip TX/RX/EnhanceRXFIFO test S32DS3.4 RTD200

As you can see in the following image, the S32K344 is pin-to-pin compatible with S32K324. So it is easier to port the examples to the MCU you are using.

Hello all,

I have tried this code for s32k324 but this is also not working. Same s32k344 code we checked in Evolution Board. It send the data in one time. In s32k324 controller CAN code not working and producing Bus error. Kindly give the clarification for CAN configuration.

Thanks you in advance

Hi @VaneB,

I've entered the following values for FlexCAN bitrate configuration and updated the code.

But the code does not get updated. Old config values are still there in the FlexCAN_Config0 structure variable. But other parameter values are gets updated.

I'm using RTD V3.0.0

Please check and update.

Hi @LavanyaR

Could you share an image of the error you are getting? Also, could you provide more details about the project's behavior?

Hi @Riyasma07

Please check the following post. Here, I am helping another customer with the same situation.

Hi @VaneB

I have checked Loop-back mode and Normal mode. But we are receiving the

Bus Error. And i don't have the clarity about those mode. Kindly explain about the modes and which mode need to choose.

Hi @LavanyaR

Sorry for the inconvenience this might cause. I am not familiar with the tool you are using.

Also, the CAN_Example was developed as a LoopBack example, so no external tools or external connections are needed.

Hi @VaneB

In Example code clock configuration have the below options are enabled.

If i enabled these options means whether it occur hard fault error or get stuck in below condition.

Hi @LavanyaR

The function Clock_Ip_GetClockFrequency returns the frequency of a given clock, in this case, FXOSC. Make sure that the clock configuration on Config Tools has the same value as your external clock/oscillator.

Hi @VaneB

In FXOSC and CAN0 to CAN5 having the same frequency. I have configures as 16MHz.

Hi @LavanyaR

Could you share your example project so I can test it from my side? Or, if it is not possible, could you share all the configurations made in COnfigTools? So I can try to replicate the problem using an example code.

Hi @VaneB

CAN driver is working now.

Thank you

Hi @VaneB

Shall we use s32k344 example driver code for s32k322 microcontroller? or Do you have driver code for s32k322 microcontroller

Hi @LavanyaR

I will be helping you with this topic in this post (Driver configuration for S32K322).
