You can start the POST execution manually by invoking the following command at the U-Boot
command line interface:.post_all()
As you can see from the syntax, this command invokes an underlying C function which starts
the POST execution. This command can be invoked at any time and it is independent of the
environment variable post_enable.

POST is executed only after hard resets. A hard reset is a
reset of the entire payload and can be issued by the
following reset sources:

Watchdog inside CPU
 Boot sequence failure
 Software
 Face plate reset key
A hard reset is NOT an CPU internal reset, such as a reset
issued through the U-Boot command reset or the
Linux command reboot.
