T1023-07C监测模块,ABB配置说明
如果使用NIOT调试器命令，则需要保存在偏移范围$00001000到$000016F7的某处。这个NIOT参数的大小不超过128字节。此环境的设置指针确定其位置。如果您已将相同的空间用于如果您拥有程序信息或命令，它们将被覆盖并丢失。您可以在此中重新定位网络接口配置参数通过使用ENV命令更改网络自动引导配置参数从默认值$00001000偏移到您需要清除NVRAM中的数据。默认结束地址是本地内存的计算大小。
T1023-07C监测模块如果内存开始从$00000000更改，该值也需要待调整。以纳秒为单位的DRAM速度=60？此参数的默认设置将根据速度而变化安装在电路板上的DRAM内存部件。默认设置达到可用DRAM内存库中的最低速度。ROM第一次访问长度（0-31）=10？这是编程到MPC105“ROMFAL”字段中的值（内存控制配置寄存器8：位23-27）以指示访问ROM时使用的时钟周期数。最低允许的ROMFAL设置为$00；允许的最高价格为1美元。这个输入的值取决于处理器速度；请参阅中列出的处理器/内存夹层模块用户手册附录D，相关文件，以获取适当的值。这个默认值根据系统的总线时钟速度而变化。注：ROM首次访问长度不适用于MVME2600/3600/4600。配置值被忽略PPCBug。
ROM下一个访问长度（0-15）=0？编程到MPC105“ROMNAL”字段中的值（存储器控制配置寄存器8：位28-31），表示等待状态半字节（或突发）模式ROM访问的访问时间。最低的允许的ROMNAL设置为$0；允许的最高金额为$F输入的值取决于处理器速度；参考您的
理器/内存夹层模块用户手册价值观默认值根据系统的总线时钟而变化速度注：ROM下一个访问长度不适用于MVME2600/MVME3600/MVME4600。配置值为被PPCBug忽略。初始化中的PIRQx（PCI中断）路由控制寄存器IBC（PCI/ISA总线桥控制器）。ENV参数是32位的值除以4得到路线控制值寄存器PIRQ0/1/2/3。默认值由系统类型决定。对于PCI/ISA中断分配和建议值的详细信息输入此参数，请参阅MVME2600程序员参考指南，见附录D，相关文件。配置VMEbus接ENV提出了以下一系列问题来设置VMEbus接口适用于MVME2300/MVME2600/MVME3600/MVME4600系列模块。要执行此配置，您应该有一个程序员手册中描述的通用ASIC知识参考指南。
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.
