How to make ARM core hung

Srikanth kumar muppandam

Hello All/ARM,

I would like to know if there is any way of process to hang a specific core for certain duration of time? Either from Kernel/User space? Also i have trying to understand if that is possible or not?

Correct me if something is there already to do it.

Thanks in advance.

    Thank you for the pointers. In order to try anyone of the methods we need either one of the dependency like JTAG, DS5 tool etc.. what i am trying is to dump the information from a driver through SW when ever an PMU event triggers. But i don't know how to test it. How easily i can replicate a core to hung for certain time to meet the time interval or timeout. If you have some solution for it, then let me know.?
