Caution

Note

Refer to the PPCBug Firmware Package User’s Manual for a listing of network controller modules currently supported by PPCBug. (Default = $00)

Network Auto Boot Abort Delay = 5?

The time in seconds that the NETboot sequence will delay before starting the boot. The purpose for the delay is to allow you the option of stopping the boot by use of the BREAK key. The time value is from 0-255 seconds. (Default = 5 seconds)

Network Auto Boot Configuration Parameters Offset (NVRAM) = 00001000?

The address where the network interface configuration parameters are to be saved/retained in NVRAM; these parameters are the necessary parameters to perform an unattended network boot. A typical offset might be $1000, but this value is application-specific. (Default = $00001000)

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.

This number is still an offset within NVRAM. However, the NVRAM image for Bug is stored at the end of flash bank A (in the last 32K).

Memory Size Enable [Y/N] = Y?

YMemory will be sized for Self Test diagnostics. (Default)

NMemory will not be sized for Self Test diagnostics.

Memory Size Starting Address = 00000000?

The default Starting Address is $00000000.

Memory Size Ending Address = 02000000?

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.
