S32K3 HardFault Error

[kranthi]

Hi, 

I am working on S32K3x4EVB_Q257 Evalboard. I have imported the example programs(CAN, UART and I2C) from RTD_4.4_1.0.0 drivers. when I am trying to debug, the execution is going to HardFault handler from Clock_Ip_DistributePll() function in Clock_ip.c file.

Below are the steps followed to import and the build

1. File->New->S32DS Project From Example.
2. S32 Configuration Tool.
3. Update code.
4. Build project.
5. Debug(Flash).

Apart from these steps do I need to configure anything for clocks/peripherals on hardware/software?

Thank you

Regards

Hello @kranthi,

Please try to compile it in Debug_RAM as specified in the description file and run it also in Debug_RAM configuration.

Hi @namnguyenviet 

Thank you for the quick response. I have tried the the UART example by compiling in Debug_RAM and run it with same. The pll clock and HardFault issues was resolved, but the execution going to undefined _handler from the Uart_AsyncSend().

I made the hardware connections(S32K3X4EVB-Q257) as mentioned in the description

PTA0(J352.22) - PTD3(J352.10)

PTA1(J352.19) - PTD2(J352.7)

did i miss anything?

Thank you

Hello @kranthi,

Turned out the interrupt handlers haven't been installed yet. Please add these lines after PlatformInit(NULL_PTR):

Platform_InstallIrqHandler(FLEXIO_IRQn, &MCL_FLEXIO_ISR, NULL_PTR);
Platform_InstallIrqHandler(LPUART3_IRQn, &LPUART_UART_IP_3_IRQHandler, NULL_PTR);

After adding these, I can run the example normally.

Hi @namnguyenviet 

Thank you for the support. yes, after adding the two interrupt handler lines the application is working fine. But if we want to Debug in Debug_Flash mode what we need to configure/change?

What is the issue? How to resolve it?

Thank you & Regards

Hello @kranthi,

The issue is from the RTD driver itself. It will be fixed in the RTM 1.0.0 release (please note that your current version is RTM 1.0.0 Code Drop 01, which is a pre-release version, and it will be replaced by RTM 1.0.0). In the meantime, please try out with Debug_RAM only.

Best Regards,

Hi @namnguyenviet ,

I'm facing issue after updating RTD drivers in S32DS which you have released on 07-oct-2021. After importing an example code into project, I used to update the code in .mex file. But post update, I'm getting some errors in Drivers as well as in MCAL drivers. Some of the errors I'm posting here.

Errors:

Issue: Mcu not found in the toolchain/IDE project. Project will not compile!

Issue: mcl not found in the toolchain/IDE project. Project will not compile!

Issue: port not found in the toolchain/IDE project. Project will not compile!

Issue: Platform not found in the toolchain/IDE project. Project will not compile!

And also I'm unable to see RTD source folder in the project which was automatically added after importing the project in the previous version.

Thank you,

Venkatesh

Hi,

@namnguyenviet  Thank you for all the support

Can please Update us That, when can we expect the  RTM 1.0.0 release, Also We have tried Normal_Can_Example  and Flex_CAN_Example on S32K344 in Debug RAM Mode, In Normal, Can Example we are facing PLL_Clock Issue, So can you please suggest us the solution for the current problems we are facing.

Thanks Again!

Hello @Anil_Kumar_M,

The RTD 1.0.0 is supposed to be delivered on 7-Oct. About the example's issue, what do you mean by normal CAN? Is that the Can_Example_S32K344 and FlexCAN_Ip_Example_S32K344? And both of them have the same issue with PLL clock? 

Best Regards,

Nam

[Anil_Kumar_M]

@namnguyenviet  Yes, We are Facing the PLL issue in  Can_Example_S32K344.

Best Regards,

Hello @Anil_Kumar_M,

The clock was setting incorrectly in both of the two examples. Please update the clock tree for both of the example as below:

Also, in the Can_Example_S32K344, the configuration set was incorrect, it should be pre-compile:

After update above things, I can run the example successfully.

Best Regards,

Hi @namnguyenviet 

I am working on FlexCAN_Ip_Example_S32K344 example. After setting the clock the application is working fine. Thank you for the support.

But I am trying to configure the CAN to interface with CAN simulator. for that I have modified the FlexCAN operation mode from loop-back mode to Normal mode or user mode IP FlexCAN driver.

And also configured the CAN Tx and RX pins.

After these configurations I am able to see the signal toggling on Tx pin while sending data. But I am unable to see the data at CAN transceiver IC out (CAN_H and CAN_L).

I have configured CAN transceiver pins as below

EN - High

STB - High

Do I need configure anything?

Thank you & Regards

Hello @kranthi,

It's a little bit tricky if you are using the CAN transceivers soldered in the EVB board - TJA1153, because these transceivers needs the pre-configuration before starting the communication. I recommend to download the TJA1153 datasheet first to have a glance of how it works. You can request for that document via your local sales representatives (that document might need a NDA contract), and unfortunately I couldn't share it in public.

Best Regards,

Nam

Hi @namnguyenviet 

Sure we will contact for the datasheet and we will go through the configuration. Thank you.
