i ahve a custom board using t2081. with hard coded rcw sysclk=133mhz and ddrclk=66mhz..
followed the connections as per the RDB. But at reset, the configuration inputs which should be pulled '1' automatically by the processor are '0'. Has any one encountered this problem? N what could be the solution? any help please
Please refer to the processor's Data Sheet and doublecheck that following points are considered/fulfilled:
1) note 5 after the Table 1. Pinout list by bus
2) 3.2 Power sequencing
3) 3.5 Power-on ramp rate
