FUNCTION: Display the flattened device tree (FDT) information, and copy FDT
information to the data buffer if required
SYNTAX:
fdt_show [] [-o]
where:
fdt_show command
parameter: string
0, 1, 2, 3
ID number of the image for which FDT information
is to be displayed
no other values than those above are supported
when not specified, displays FDT information for
image in the data buffer
-o option: overwrite
copy FDT contents to the data buffer (will overwrite
any image in data buffer)
DESCRIPTION: This command is used to have the NetBootLoader display the
contents of the FDT for the image specified (for the currently specified
core).
Use the “-o” option to force writing of the FDT contents to the data
buffer. Once in the data buffer, the FDT information can transferred to
a server.
The information provided can be used for system analysis or
diagnostic purposes.
Some older NetBootLoader versions do not support the “-o” option. In
this case, the FDT contents are copied to the data buffer and any
image in the data buffer is overwritten.
If the “-o” option is not specified with NetBootLoader versions which
support it, the FDT contents are copied to the top of RAM.
