How can I reset C6747 by using software?

Hi

A device/chip level reset cannot be initiated via software/application itself. The power on reset and warm reset can be initiated by a combination of the RESETn and TRSTn pins as specified in the datasheet , Section 6.5.

The only atypical way I can think of is to allow a watchdog timeout event by  deliberately not servicing it.

The device does allow "local" or Sync reset to various modules and c674x core itself via the power sleep controller (PSC). This is explained in the system guide , PSC chapter (Chapter 8)

Using the watchdog timer, you can also write an invalid key value to cause an immediate reset:

void watchdog_reset_now(void)
{
    if(!WATCHDOG_RUNNING)
    {
        watchdog_enable();
    }
    gTimer64P1.regs->WDTCR = (uint32_t)WATCHDOG_SEQ1; //go to service state
    gTimer64P1.regs->WDTCR = (uint32_t)0 ; //Invalid key cause a reset
}
