    you didn't tell what target platform you use.

    i assume that you have external memory at adr 0x00800000

    if yes you use external memory, have you tried to run from internal memory ?

    do you have timing violations ?

    do you use SDRam ? if yes, what about the sdram clock phase shift ?
