If you use the NIOT debugger command, these parameters need to be
saved somewhere in the offset range $00001000 through $000016F7. The
NIOT parameters do not exceed 128 bytes in size. The setting of this ENV
pointer determines their location. If you have used the same space for your
own program information or commands, they will be overwritten and lost.
You can relocate the network interface configuration parameters in this
space by using the ENV command to change the Network Auto Boot
Configuration Parameters Offset from its default of $00001000 to the
value you need to be clear of your data within NVRAM.
The default Ending Address is the calculated size of local memory. If
the memory start is changed from $00000000, this value will also need
to be adjusted.
DRAM Speed in NANO Seconds = 60?
The default setting for this parameter will vary depending on the speed
of the DRAM memory parts installed on the board. The default is set
to the slowest speed found on the available banks of DRAM memory.
ROM First Access Length (0 - 31) = 10?
This is the value programmed into the MPC105 “ROMFAL” field
(Memory Control Configuration Register 8: bits 23-27) to indicate the
number of clock cycles used in accessing the ROM. The lowest
allowable ROMFAL setting is $00; the highest allowable is $1F. The
value to enter depends on processor speed; refer to yourProcessor/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.Initializes the PIRQx (PCI Interrupts) route control registers in the
IBC (PCI/ISA bus bridge controller). The ENV parameter is a 32-bit
value that is divided by four to yield the values for route control
registers PIRQ0/1/2/3. The default is determined by system type. For
details on PCI/ISA interrupt assignments and for suggested values to
enter for this parameter, refer to the 8259 Interrupts section of the
MVME2600 Programmer’s Reference Guide, listed in Appendix D,
Related Documentation.
Configuring the VMEbus Interface
ENV asks the following series of questions to set up the VMEbus interface
for the MVME2300/MVME2600/MVME3600 /MVME4600 series
modules. To perform this configuration, you should have a working
knowledge of the Universe ASIC as described in the Programmer’s
Reference Guide.
