Monitor: Environment Parameter Commands

ENVIRONMENT PARAMETER COMMANDS

The monitor uses on-board, non-volatile memory for the storage of environment parame- ters. Environment parameters are stored as ASCII strings with the following format.

<Parameter Name>=<Parameter Value>

Some environment variables are used for board configuration and identification by the monitor. The environment parameter commands deal with the reading and writing of these parameters. Refer to “Environment Variables” on page 11-22for a list of monitor environment variables.

printenv

The printenv command displays all of the environment variables and their current values to the display.

DEFINITION: Print the values of all environment variables.

printenv

Print the values of all environment variable (exact match) ‘name’.

printenv name …

saveenv

The saveenv command writes the environment variables to non-volatile memory.

DEFINITION: saveenv

setenv

The setenv command adds new environment variables, sets the values of existing environ- ment variables, and deletes unwanted environment variables.

DEFINITION: Set the environment variable name to value or adds the new variable name and value to the environment.

setenv name value

Removes the environment variable name from the environment.

setenv name

TEST COMMANDS
