New Blank S32K344 project Bus Fault and Hard Fault

[Yown]

Hi, 

I have create a new S32K344 blank project in S32Ds 3.5 with RTD 4.0.0. when I am trying to debug, the execution is going to HardFault , The same goes for using sample projects,

but when i create a new blank S32K324 project, it work

Below are the steps followed to import and the build

1. File->New->S32DS application project
2. add sdk
3. Update code.
4. Build project -> no error.
5. Debug(Flash).

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

Thank you

Regards

Hi @Yown,

Are the cores decoupled or in the lockstep mode?

Can you read Processor X Configuration 2 (CPXCFG2) register.

i fix it and it works, thank you very much, Are there any references for this knowledge, For example, is the default operating mode of core is decoupled 

[Yown]

thanks for your guidance, it took me a while to find them

so in decoupled mode, should i need to change configuration of dtcm size

[danielmartynek]

S32K344 is in the lockstep mode by default, whereas S32K324 is decoupled by default.

It can be changed in the DCF record.

Here is an example that programs a new DCF record on S32K344 to decouple it:

Sorry Daniel, I'm a little confused, i didn't change anything but create a new project, according to the CPXCFG2, is decoupled mode, is there any project configuration wrong i should check?

at this stage, i just want to make sure S32K344 start normal, so i can keep rtos kernel develop on it , the way i fix the issue above is change itcm size to 32KB and dtcm to 64KB, seem i need to run core in lockstep

and in the example you provided, "C40_Ip_Cfg.h" missed, how can i get it

[danielmartynek]

C40_Ip_Cfg.h is not missing, it is in this directory:

Example_S32K344_decouple_RTD400_Ip_C40_DS35_v1.zip\Example_S32K344_decouple_RTD400_Ip_C40_DS35_v1\generate\include

You don't have S32K344 but S32K324 now.

Check the DCF records at 0x1B000768.

If you had S32K344 with the default DCF, at 0x1B000768, there would be all 0xFFFF_FFFF.

Thanks for your patience~ it really isn't all 0xFFFF

in the board, Silicon: P32K344EHVMMS 1P55A CTSA2128A
I can't figure out their relationship, So do I need to continue to develop refer to S32K324 project?

[danielmartynek]

Probably one of your colleagues decoupled the S32K344 MCU into S32K324.

You need to program a new DCF record (at the next 0xFFFF_FFFF after the current record) from an S32K324 project to make it S32K344 again.

i think the problem is about dtcm initialize, i can't step out this loop but get hardfault
