=============
|

|
|
|
||
|
|
This is a tiny procfs file system that allows read-only access to a few
|
||
|
|
attributes of a task or thread. This tiny procfs fs file system can be
|
||
|
|
built into the system by enabling::
|
||
|
|
|
||
|
|
CONFIG_FS_PROCFS=y
|
||
|
|
|
||
|
|
It can then be mounted from the NSH command like like::
|
||
|
|
|
||
|
|
nsh> mount -t procfs /proc
|
||
|
|
|
||
|
|
Example::
|
||
|
|
|
||
|
|
NuttShell (NSH) NuttX-6.31
|
||
|
|
nsh> mount -t procfs /proc
