Erase flash memory
Syntax
eflash <address> [ <size> ]
Parameters
address
defines the starting address of the flash memory to be erased
size
defines the size of the flash memory to be erased

pflash
env
Create, modify or remove environment variable
Syntax
env [ <name> [ <value> ] ]
env clear
env load
env save
Parameters
name
defines the name of the environment variable or the environment function
value
defines the value of the environment variable
Description
The env command allows several functions depending on the parameters passed:
<name> <value> Function
no
no
All the current environment variables are displayed
yes
no
The <name> environment variable is removed
yes
yes
The <name> environment variable is created or modified with <value>
Any environment variable name can be used except 'clear' (remove all current environment
variables), 'save' (save all current environment variables in the non-volatile RAM), and 'load' (load
current environment variables from the non-volatile RAM).
Please note :
The 'BOOTARGS' environment variable is used during a call to an external routine.
The 'AUTOBOOT' environment variable is used as the first command line after power-up.
The 'AUTOWAIT' environment variable defines the timeout (number of seconds) for the
AUTOBOOT condition (0 = disabled). After a power-up, ECMon uses these both
environment variables to provide an autoboot feature (during the waiting time, while the
keystroke 'carriage return' start the autoboot command, the keystroke 'escape' abort the
autoboot command).
If the <value> parameter must contain space or tabulation characters (such as for the
'AUTOBOOT' environment variable), the double-quote character must start and end the
<value> data (e.g. env AUTOBOOT "nboot 2 0 0 bootfile").
The 'TERM' environment variable can be set to 'ansi' to provide an ANSI console.
