Hello,
 
I have the following problem on a TQM859 CCM card with MPC859:

I have this problem with a clock frequency of 66,5 MHz,  but if I go at 62
MHZ, the problem disappears and everything works properly.
I investigate on a SDRAM problem, but up to know I am focusing on FLASH.
Do you have any suggestions about how to solve my problem?
 
Thanks
 
Ciao
