Synopsis

--------

|
|
::
|
|
|

config [<str>]
|
|
|
|
Description
|
|
-----------
|
|
|
|
The config command prints the `.config` file used when building U-Boot
|
|
to the console. Note that the `.config` file is usually several 1000
|
|
lines long.
|
|
|
|
If the optional argument is given, only lines containing that string
|
|
(case insensitively) are printed. That can be useful if one wants to
|
|
check whether a specific option is enabled, or just to limit the
|
|
output to the subsystem of interest.
|
|
|
|
The `.config` file is stored inside the U-Boot binary in
|
|
gzip-compressed format.
|

Examples

|
