MPC5644A mounted on S32DS can not open interrupt S32DS is a big bug IDE?

[alexhuang5367]

I've porting CW10.6 project into S32DS and it use MPC5644A

then CW10.6 it can be work but S32DS can not work

error message is here and attachment is source code

when i run this code i always find "Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000004 in RCHW2 ()" this problem, then S32DS stop debug

Could someone can provide a MPC5644A moounted on S32DS example?

Hi Alex,

I will try to port your code to S32DS next week.

Just one question. Are you able to load default project for MPC5644A to your microcontroller?

Regards,

Martin

Hi Martin

Thank you so much.

Yes, I've used the default head file and source code in the project.

If you have any questions or whole project, please do not hesitate to contact me

Sincerely,

Alex

Hi Alex,

I have created simple example based on the code you shared in the first post. I am able to load to to microcontroller flash memory and also RAM memory. It is important to use S32 Design Studio version 1.1 (the older version does not support MPC5644A).

Which debug probe you use for loading the code?

Import the project I created and try to load it to your microcontroller.

Regards,

Martin

PS: I did not implement interrupt handler, so PIT interrupt does not work, but you should be able to debug the rest of the code. Do not forget you have to use only debug icon for loading the code. Run icon does not work.

Regards,

Martin

This is my problem, when i open the PIT interrupt

I'm so confuse about the error message

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000004 in RCHW2 ()

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000006 in RCHW2 ()

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000004 in RCHW2 ()

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000006 in RCHW2 ()

Program received signal SIGTRAP, Trace/breakpoint trap.
0x00000004 in RCHW2 ()

This page just show you what debug prob i use

Hi Alex,

I found the issue. In MPC56xx__Interrupts_Init.c file is function InitIVORS, which is not compiled, because neither symbol E200Z4 nor symbol E200Z7 is defined. If you use e200z4 core, it is necessary to initialize IVOR registers (which is not done in the project).

So the simple workaround is to define symbol E200Z4 for compiler. Open project properties, open tab Symbols in compiler sub-menu and add new symbol. Recompile the project.

Now it will work.

Regards,

Martin

AWESOME!!

Thank your so much for your help, I really appreciate it.

How did you find it? Compare with MPC574x or MPC5643 project or Assembly code?

I really want to know that, if you convenience please tell me.

Hi Alex,

I did not compare any project. I took the project I shared here and I loaded it to microcontroller using Lauterbach debugger. Then I stepped through xcptn_xmpl function. I saw there is no code in InitIVORS function. From my knowledge of e200z4 core I know, I have to initialize single IVOR registers with correct values and that is it.

I had opened MPC56xx_interrupt_Init.c file and I found there is conditional compilation and neither E200Z4 symbol nor E200Z7 symbol is defined.

I have escalated this issue to appropriate team. So it should be fixed in next S32DS release. 

If you have any other question, please feel free to write me back.

Regards,

Martin
