Doubt about the REST on Proto Board

I met a strange situation that my propeller core seem getslow its processing speed after I push "REST" button instead of power-off then restart. I use alsmot 8 cogs in my system including ultrasonic sensors, GPS sensor receiver, IMU sensor, RS232 communication, datalogger, and the other two for checking procedures.

Whenever I REST the propeller, I will get a slow speed of my program. If I use power-off the propeller, it can work normally as I wish. How can I debug this situation ?

    KevinKK,

    That sounds a little odd.. one way to debug this might be to issue a "REBOOT" command from within the Propeller. This essentially is a software reset button.

    Another method would be to post your code, you could be over-writing something in your EEPROM that could be causing the problem.

    very thanks for your instruction.
    Finally, we choose two steps for this event.
    1. we remove some data storage commands to decrease the time delay between Datalogger.
    2. We purchase your SD card and adapter to replace datalogger.

    Once we get better response, I will go back post again.
