Modifying the Environment

Caution

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.

Memory Size Enable [Y/N] = Y?

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.

ROM First Access Length (0 - 31) = 10?

This is the value programmed into the“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

Memory will be sized for Self Test diagnostics.

(Default)

Memory will not be sized for Self Test diagnostics.
