TMS320C6657: RESETFULL not functioning the same as a power cycle

Part Number:TMS320C6657

Hi

We are experiencing an issue where the DSP does not appear to initialise properly (possibly cache issues) after RESETFULL.

It is our understanding that a RESETFULL should be functionally equivalent to a power cycle of the device but this does not seem to be the case everytime. In a previous thread there was mention of the software running having some effect on the behaviour of RESETFULL but that thread went dead.

Our reset pulsewidth is 150mS and the reset stat timing appears to be correct.

Any help would be appreciated.

Thanks
