Does hifive unleashed freedom u540 have suspend state

I am running kselftest on hifive unleashed freedom u540.
In selftests it has breakpoints test suite, which has step_after_suspend_test test.
After running step_after_suspend_test it gives the following log:


selftests: breakpoints: step_after_suspend_test

TAP version 13


Bail out! Failed to enter Suspend state

# Planned tests != run tests (229 != 0)

# Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0

not ok 1 selftests: breakpoints: step_after_suspend_test # exit=1

So my question is does freedom u540 supports any suspend state?

I believed FU540 doesn’t have the power management implemented
