Description
|
|
-----------
|
|
|
|
The *efidebug* command provides access to debugging features for the EFI-loader
|
|
subsystem.
|
|
|
|
Only one of the subcommands are documented at present.

efidebug log
|
|
~~~~~~~~~~~~
|
|
|
|
This shows a log of EFI boot-services calls which have been handled since U-Boot
|
|
started. This can be useful to see what the app is doing, or even what U-Boot
|
|
itself has called.
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
This shows checking the log, then using 'efidebug tables' to fully set up the
|
|
EFI-loader subsystem, then checking the log again::
