6. The moninit command does not initialize these variables. Each parameter is only defined if a change from
the default setting is desired and is not defined after initialization of the environment variables.
TROUBLESHOOTING
To bypass the full board initialization sequence, attach a terminal to the console located on
the front of the KAT4000. Configure the terminal parameters to be:
9600 bps, no parity, 8 data bits, 1 stop bit
Reset the KAT4000 while holding down the ‘s’ key. Pressing the ‘s’ key forces a configura-
tion based on default environment variables.
app_lock_size Size of user NOR (soldered) flash protection area.
bootverifycmd Sets the U-Boot boot command that is used to execute the primary and
secondary application images when using the bootv command. If not defined,
bootv uses the U-Boot go command as the default.
dhcp-client-id Populates the Client Identifier (Option 61) in the DHCP request Packet. See
“dhcp” on page -10.
dhcp-user-class Populates the User Class Information (Option 77) in the DHCP request Packet.
See “dhcp” on page -10.
e_keying Enables the Update Channels and payload ports that go off the KAT4000: fat
pipe switch module to high-speed fabric, fat pipe switch module to AMCs, and
GbE from fat pipe switch module to Ethernet core switch. For debug use only. If
e-keying is set to ”on” or if the variable is not present, the ports are disabled. The
e-keying variable is only used on power-up.
pri_bootargs Sets the boot arguments that are passed into the primary application images
when using the bootv command. If not defined, bootv will pass the bootargs
configuration parameters into the primary application image.
pci_memsize Sets the amount of SDRAM memory made available on the PCI bus. The
minimum setting is 16 megabytes. If not set, 128 MB of SDRAM are available
over PCI. This parameter takes a hex value.
Valid options: all, size in hex (0x8000000=128 MB)
pram This memory region is at the very top of memory and can be reserved—not to be
cleared on start-up or reset. Default size of the protected memory region is 0.
pram is defined in kilobytes and is a base 10 number. The smallest allowable size
is 4 (4 kB) and the largest recommended size is 32768 (32 MB). pram should be 4
kB aligned, otherwise U-Boot will round pram to the next 4 kB size.
sec_bootargs Sets the boot arguments that are passed into the secondary application images
when using the bootv command. If not defined, bootv will pass the bootargs
configuration parameters into both the primary and secondary application
images.
