Dear Sir,
Our product is installed on an automotive environment.
Currently, we meet a problem with DM642 DSP reset.
When we turn on and turn off our system power repeatedly & quickly and the last power state remains on, but our system does not boot as normal.
But when we push our hardware reset button to re-trigger the reset pin of DSP DM642, the system can boot normally.
Why the DM642 DSP can not boot normally when the power state change rapidly?
What can we do to avoid the problem?
Really appreciate your help!!
Best Regards,
Eric Fang
