Hi Peter,

I am working on S32R274 and I need help for SWT_2.

I need your help regarding above code :

I am not able to see the NCFS_CFG0 is getting updated with my value 0x40000000 .

FCCU.NCFS_CFG[0].R = 0x40000000;.

and I can see that, NCF_S0  is showing value 0x00070000.

Below are the screen shot during debug :

Could please help me,. why this value NCF_S0 = 0x00070000, as I have just configure SWT_2 only.

and why I am not able to see the my written value in NCFS_CFG0.

Thanks !

Hi,

Hmm, and do you performing FCCU configuration in FCCU CONFIG mode?

Peter

Hi Peter, 

If timeout expires the SWT causes a reset, after this reset next timeout the SWT no longer reset.

I try the interrupt mode and the IR is correctly triggered in both cases but no reset after first reset.

What could be the problem?

What can I check?

Thank in advance.

Salvatore.

Hi,

Since you did not share much about your test setup, I guess it can be debugger whose preventing the code run or simply disable SWT as most debuggers do automatically.

Peter

Sorry, I've solved the problem. I had commented FCCU_clear_faults(). Now work.

Thanks
