Reset device from code

TobyM

Hi Folks,

Is it possible to reset/reboot/restart a device from code? E.g. if a detected error cannot be resolved except by restarting the device then call c_init00() or something...

Hi Toby,

There is not true software reset available in the F28xxx devices. You can accomplish this by triggering the Watchdog Timer in software. To do this you need to write the wrong key value to the WDCHK bits of WDCR. This is described in the System Control and Interrupts Reference Guide for your device.

Gautam

Hi, Toby,

at least watchdog is the most robust way to restart in case of failure. Using any software solution will be inferior in reliability when certain kinds of failures.

Igor
