Hi AURIX Community,

Do you know what is the difference between CPU watchdog and safety watchdog?

Thank you.

Hi Bernie,


CPU watchdog timers:
Help recover from an accidental malfunction of a CPU core
Provides protection against unintended writes to critical CPU registers

Safety watchdog timer:
Provides an overall system level watchdog, independent of CPU cores
Provides protection against unintended writes to safety critical system registers


Best regards

Hello,

Similar to the CPU Watchdog example as in https://www.infineon.com/dgdl/Infineon-AURIX_Watchdog_1-Training-v01_00-EN.pdf?fileId=5546d4626f2295...

Is it possible to provide an example of using the safety watchdog timer? It will be really useful.

Best regards
Padma
