Optional Environment Variables
TROUBLESHOOTING
To bypass the full board initialization sequence, attach a terminal to the console located on
the front of the module. Configure the terminal parameters to be:
9600 bps, no parity, 8 data bits, 1 stop bit
Reset the module while holding down the ‘s’ key. Pressing the ‘s’ key forces a configuration
based on default environment variables.
Variable
1
:
1. 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 configuration variables.
Description:
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.
dcache
Enables the processor L1 data cache. If not defined, the default is (on).
Valid options: on, off
ecc
Enables ECC initialization—all of memory is cleared during ECC initialization.
If not defined, the default is (on). Valid options: on, off
eready
Wait for PCI EREADY signal before enumeration as a Monarch? This only
applies to power-up enumeration when the board is a Monarch. If not
defined, the default is (on). Valid options: on, off
eready_wait
Sets the EREADY wait time-out value when the eready parameter is set to
on. This parameter takes a decimal value.
icache
Enables the processor L1 cache instruction. If not defined, default is (on).
Valid options: on, off
l2cache
Turns the L2 cache on or off. If not defined, default is (on).
Valid options: on, off
pci_bus
Selects the PCI bus for enumeration. If not defined, default is (0).
Valid options: 0, 1
pci_memsize
Sets the amount of SDRAM memory made available on the PCI bus. This
parameter is applicable when the board is either the Monarch or non-
Monarch. The minimum setting is 16 megabytes. If not set, 128 MB of
SDRAM are available over PCI.
Valid options: all, size in hex (0x8000000=128 MB)
pri_bootargs
Sets the boot arguments that are passed into the primary application
images when using the bootv command. If not defined, the bootv will pass
the
bootargs
configuration parameters into the primary application image.
sec_bootargs
Sets the boot arguments that are passed into the secondary application
images when using the bootv command. If not defined, the bootv will pass
the
bootargs
configuration parameters into the secondary application
image.
