Honored Contributor --- Quote Start --- Hi thanks for reply. clock frequency is 300 MHz. Yes I will look with a scope but since the problem is only present after particular resets/calibrations I'd not thought of it as a possible cause of the problem. I will also try slowing down the clock as you suggest. Thanks Dave --- Quote End --- Hi I've slowed the clock down to 250MHz with no improvement. :(
