Caution
If you use the NIOT debugger command, these parameters need
to be saved somewhere in the offset range 0x00001000 through
0x000016F7. 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
0x00001000 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 0x00000000.
Memory Size Ending Address = 02000000?
The default Ending Address is the calculated size of local memory. If
the memory start is changed from 0x00000000, this value will also
need to be adjusted.
DRAM Speed in NANO Seconds = 15?
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.
Y
Memory will be sized for Self-Test diagnostics.
(Default)
N
Memory will not be sized for Self-Test diagnostics.
