Description
|
|
-----------
|
|
|
|
The host command provides a way to attach disk images on the host to U-Boot
|
|
sandbox. This can be useful for testing U-Boot's filesystem implementations.
|
|
|
|
Common arguments:
|
|
|
|
<label|seq>
|
|
This is used to specify a host device. It can either be a label (a string)
|
|
or the sequence number of the device. An invalid value causes the command
|
|
to fail.
|
|
|
|
|
|
host bind
|
|
~~~~~~~~~
|
|
|
|
This creates a new host device and binds a file to it.
|
|
|
|
Arguments:

|
|
|
|
|
host unbind
|
|
~~~~~~~~~~~
|
|
|
|
This unbinds a host device that was previously bound. The sequence numbers of
|
|
other devices remain unchanged.
|
|
|
|
|
|
host info
|
|
~~~~~~~~~
|
|
|
|
Provides information about a particular host binding, or all of them.
|
|
|
|
|
|

|
Allowing selecting a particular device, or (with no arguments) seeing which one
|
|
is selected.

|
|
dev blocks label path

|
|
|
Bind a device::
|
|
|
|
=> host bind -r test2 2MB.ext2.img
|
|
=> host bind fat 1MB.fat32.img
|
|
=> host info
|
|
dev blocks label path
|
|
0 4096 test2 2MB.ext2.img
|
|
1 2048 fat 1MB.fat32.img
|
|
|
|
Select a device by label or sequence number::
|

|
|
Current host device: 1: fat
|
|
=> host dev 0
|
|
Current host device: 0: test2
|
