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.
There is no issue with watchdog. But still wanted to know more information why the core hung happened. Either it can be silicon or SW issue.
Hello,
I'm sorry but I have no answer for your question.
How about trying Undo's debug tools?

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.?
