25 seconds problem!

I am posting this mail for Vijay since he was unable to get through 
for some reason.

Vijay - you should look at the following:

1) HRESET to see if the part is getting reset. This could indicate 
the watchdog is kicking in after 25seconds.

2) Examine the reset status register to see what the reset source was.

3) Look at CLKOUT relative to POR and HRESET as an indication of PLL 
status.

4) temporary comment any startup code you have that waits for PLL to 
lock to see if that is the cause of delay.

5) ENGCLK - what you describe sounds like your s/w must have ran and 
changed sysclk to 40MHz but doesn't get as far as changing the ENGCLK 
from default /64 to /1 (which I presume your s/w does at some point).

Regards, 
Allan

Hi Allan
        I have a strange problem. If you remember I had explained 
earlier about our project we are trying to develop an MPC565 board 
for Gas Engine ignition management. Our first prototype worked fine 
but this new prototype has a problem. After board is powered up 
for "25 seconds" the MPC565 does nothing then normal execution from 
my firmware resumes. I use the TouCAN,QADC,QSMCM,TPU and it is single 
chip configuration. There are no special options, I am just using it 
with defaults. I checked my firmware operation it works fine after 25 
seconds. I checked the RCW, crystal, POR etc and I am unable to track 
the cause of this problem.
 The interesting thing is the processor always sleeps for 25 seconds 
and during that time the engclk is 40MHz/64 and once it starts 
executing it goes back to 40MHz.My part number is MPC565CZP40. So my 
question is why is there such a large delay in execution and 
what is the cause of it? What is puzzling is that there are no 
changes between the two boards on the processor side yet we have this 
problem.
I tried posting my message on the group but it somehow doesnt get 
through? and I checked the archives nobody had this problem before. 
Can you please provide me some pointers regarding this. I appreciate 
your help.

Thanks& Regards
Vijay Lakshminarayanan
