When enable coresight and hang on Hikey, could you try to disable CPUIdle totally? You can remove CPUIdle related configurations in .config or you can add 'nohlt' into kernel command line.
Leo is correct - this is the first thing to look at.
Thanks Leo and Mathieu for the suggestion. With that change my board still does not boot correctly. Here is how I disabled CPUIDLE in my config file:
--- .config-1 2017-05-15 10:21:48.157466820 -0500 +++ .config 2017-05-16 15:26:55.955816933 -0500 @@ -559,15 +559,7 @@ # # CPU Idle # -CONFIG_CPU_IDLE=y -CONFIG_CPU_IDLE_GOV_LADDER=y -CONFIG_CPU_IDLE_GOV_MENU=y -CONFIG_DT_IDLE_STATES=y
This will definitly disable CPUidle - and you are using a perf-opencsd-v4.11 kernel?
