ENV – Set Environment

Processor/Memory Mezzanine Module User’s Manual, listed in Appendix D, Related Documentation, for appropriate values. The default value varies according to the system’s bus clock speed.

Note ROM First Access Length is not applicable to the MVME2600/3600/4600. The configured value is ignored by PPCBug.

ROM Next Access Length (0 - 15) = 0?

The value programmed into the MPC105 “ROMNAL” field (Memory Control Configuration Register 8: bits 28-31) to represent wait states in access time for nibble (or burst) mode ROM accesses. The lowest allowable ROMNAL setting is $0; the highest allowable is $F. The value to enter depends on processor speed; refer to your Processor/Memory Mezzanine Module User’s Manual for appropriate values. The default value varies according to the system’s bus clock speed.

Note ROM Next Access Length is not applicable to the MVME2600/MVME3600/MVME4600. The configured value is ignored by PPCBug.

DRAM Parity Enable [On-Detection/Always/Never - O/A/N] = O?

ODRAM parity is enabled upon detection. (Default)

ADRAM parity is always enabled.

NDRAM parity is never enabled.

Note This parameter (above) also applies to enabling ECC for DRAM.
