problem hardFault generated by sw32k3_FreeRTOS

[michelet1]

Hello,

i have s32ds 3.5 and i'm using the board MCTPTX1AK324(and follow step provided to get started) with installation RTD 4.4 2.0.0,  IPCF 4.0.0.

As a next step i tried to allocate a static task and the related scheduler function(vTaskStartScheduler).

I modified FreeRTOSConfig.h to have static allocation etc.. but when I start the code and debug with PE micro it generates hardFault() when it executes prvPortStartFirstTask(void) function in vTaskStartScheduler.

I also tried looking for possible solution(as insert define MCAL_ENABLE_USER_MODE_SUPPORT)  but i couldn't solve it.

In the attachment i report the image of the main with static task allocation and the scheduler.

 Thank you in advance for your help and availability

Hello @michelet1,

Do you enable the "static allocation"?

If not, please let me the correct statement in the task_scheduler function was occurred hardfault error. Besides, Could you send me your example?

Best regards,

Good evening,

thanks for your answer but my problem is the following:

I started from the following link (https://www.nxp.com/design/development-boards/automotive-development-platforms/s32k-mcu-platforms/s3...)  in order to try dual core reference design of s32k324.

I  need to work with s32ds3.5 but this reference design only work with RTD 2.0.0.   In fact if i try to install RTD 3.0.0 and then open configuration tool from s32ds3.5 it generates the error that i report in the attachment.

So my doubt is: Starting from reference design of the s32k3 it is possible to use RTD 3.0.0?

Using s32ds3.5 i should use RTD 3.0.0 and FreeRTOS 10.5.1 ? it seems to me that this is the only possible combination

Thank you very much for your precious help and collaboration

Hello @michelet1,

Using s32ds3.5 i should use RTD 3.0.0 and FreeRTOS 10.5.1?

=> Yes, because SW32K3_FreeRTOS_10_5_1_UOS_3_1_0_D2304 package based on the RTD 3.0.0.

And RTD 3.0.0 only can install on the S32DS 3.5.

with  RTD 2.0.0, this package based on the  S32 Design Studio IDE v3.4 Update 3.

Best regards,

Good morning, 

thanks for the confirmation regarding RTD 3.0.0.

The doubt remains that how do i make the reference design(https://www.nxp.com/design/development-boards/automotive-development-platforms/s32k-mcu-platforms/s3...) work on the s32ds3.5?

this reference works with RTD 2.0.0, is it possible to make it work with RTD 3.0.0?

Thanks again for your precious help and collaboration.

=> Yes, it is.

good morning,

but once RTD 3.0.0 has been installed I can no longer open the configTool (i.e. the .mex file) and it generates the error in the attachment.

How do I resolve this?

Thanks again for your precious help

Hello @michelet1,

Did you install and use correct S32DS update side for RTD K3 3.0.0 version?

Best regards,

Dan

[michelet1]

Hello, 

first i deleted RTD 2.0.0 and then i went under Help->s32ds design studio extensions and updates->select RTD 3.0.0 as the following image shows.

Do i have to do some further steps? because after installing RTD 3.0.0 i  can no longer open config tool(.mex file) and it generates an error that i showed before here on the forum.

Thanks again very much for your help

Hello @michelet1,

Maybe you was not install development package for S32K3XX before install RTD 3.0.0 package.

This is the sequence to install RTD 3.0.0 package:

First, you need to install development package for S32K3XX, download at the highlighted path as image below.

After install this development package completed, you will install RTD S32K3 3.0.0

Best regards,

Dan

Good evening,

thank you for your precious help.

I only have one more doubt: when i also add FreeRTOS and call vTaskStartScheduler. At a certain point the prvPortStartFirstTask function is executed and at this point the k324 microcontroller generates HardFault.

Why does this behavior happen? Is it due to the address 0XE000ED08? in the attachment i report two screens with the fundamental points of the code that concern this problem

I hope i was clear in explaining my problem. i take this opportunity to thank you again for your precious help.

Hello @michelet1,

Could you send me your project?

Best regards,

Hello,

right now i'm doing some tests with triple motor k3 reference design project.

In attachment i report the project.(is file .exe for install reference design project s32k324 on your PC)

i would like to at least be able to make freertos work on this project(in this case i'm using RTD 2.0.0 and s32ds3.4 with freertos 10.4.5)

thanks again for your availability

Best regards

Hello @michelet1,

I can't install your .exe file into my PC because it violates the secure policy of NXP.

Could you send me the .zip file of your project?

Best regards,

Dan

[michelet1]

Good morning,

I will send you the project in 7z zip format.

Inside there is the dual core s32k324 project. I tried to install FreeRTOS first in core0 and then on core1 but still there was a HardFault when prvPortStartFirstTask is executed.

 Thanks again for your precious help and collaboration

Hello @michelet1,

The FreeRTOS didn't support multi-core scenarios. So, you can't implement FreeRTOS with dual-core.

Best regards,

Dan

Good morning,

thanks for your info.

I still have a couple of questions to understand better:

1) it is not possible to use any operating system in the dual core s32k324 case?

2)is this a temporary thing/ in the future you can use freertos on the dual core?

Thanks again for your precious help.

Best regards

[DanNguyenDuy]

Hello @michelet1,

1) it is not possible to use any operating system in the dual-core s32k324 case?

=> I only can confirm that you can't use the FreeRTOS packages for multi-core.

2)is this a temporary thing/ in the future you can use freertos on the dual core?

=> I only know that, at the moment, there are not any FreeRTOS packages that support multi-core.

Best regards,

Dan
