Config MC33908

Hi Guys,

I'm trying to config the safety mode of the MC33908 SBC, throught an MPC5643L. I have a lot of problems with the Watchdog and the initialization of the safety mode.

Has anybody worked with this chip, or have you any initialization example, that I can use as a template?

I can achive the normal mode, but I get several WD errors, so I think that I am not doing the right thing.

Thanks a lot in advance

Pablo

Hi Pablo,

Sorry for the delay in answering your question.

The example project (KITMPC5643DBEVM Demo Code) available for the KITMPC5643DBEVM might be a good reference for you.

I hope it helps.

Regards,

Tomas

I am facing problems with the MC33907.

I can perfectly work in debug mode, I can successfully refresh the watchdog, everything is fine. However, when I exit the debug mode putting a pull down in the debug pin and do a power on reset. The supply starts putting the reset low during aprox. 8 seconds and then everything is shut down. What am I doing wrong?
