The monitor supports optional environment variables that enable additional functionality. The moninit command (see “moninit” on page 11-20)only affects the standard environ- ment variables and does not set any parameters for these optional variables.

Table 11-3:Optional Environment Variables

Variable:1	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.

eready_wait	Sets the EREADY wait timeout value when the eready parameter is set to
	on. This parameter takes a decimal value.

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.
