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?
