Management Processor Monitor: Environment Parameter
10009109-01 ATCA-9305 User’s Manual
9-19
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 “MPC8548 Environment Variables” on page 9-26 for a list of monitor
environment variables.
Redundant environment parameters allow you to store a “backup” copy of environment
parameters should they ever become corrupt. The redundant environment parameters are
only used if the main parameters are corrupt.
To save environment variables:
1 Use moninit to save default environment variables to both primary and secondary
environment parameters.
2 Use saveenv to save to the primary environment variables.
3 Set the next save to the secondary image.
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.
