Configuration
|
||
|
|
-------------
|
||
|
|
|
||
|
|
The bootz command is only available if CONFIG_CMD_BOOTZ=y.
|
||
|
|
|
||
|
|
Return value
|
||
|
|
------------
|
||
|
|
|
||
|
|
Normally this command does not return. If an error occurs, the return value $?
|
||
|
|
is set to 1 (false). If the operating system returns to U-Boot, the system is
|
||
|
|
reset.
