Hi:

 When I entered the “poweroff” command, I found that it would restart in about one minute on the ls1028 platform.

$:poweroff

The LS1028ARDB board does not support power off possibility from software. See the Section 2.2 in the LS1028ARDB board Reference Manual:

Only power switch for the LTC2955-2 provides power off for this board.

Hi:

Will you implement software poweroff in the future?We have designed the development board according to ls1028ardb board. If we want to realize the software poweroff, do you have any suggestions?

Add the R431 and the R432 on the LS1029ARDB board to generate KILL from 12V directly.
