-------------- U-Boot consoles ------------------
|
||
|
|
||
|
U-Boot supports multiple consoles which may be simultaneously active.
|
||
|
Depending on the configuration none, the first or all consoles are
|
||
|
activated on startup, see CONSOLE_ACTIVATE_FIRST and CONSOLE_ACTIVATE_ALL
|
||
|
options.
|
||
|
|
||
|
During runtime the behaviour of the consoles can be controlled with the
|
||
|
'active' parameter each console has. The console system recognizes three
|
||
|
characters: 'i' for stdin, 'o' for stdout and 'e' for stderr. These options
|
||
|
may be concatenated together as needed, so setting an 'active' parameter
|
||
|
of a console to 'io' would enable it for stdout and stdin while leaving
|
||
|
stderr disabled.
