I have working device, that operates with RAM (random access memory). I want to grab RAM dump. I think it must be a hardware option. Is there a way to do this? Maybe anybody have some expirience?

  • What OS? What chipset? I'm afraid this question might be too broad. – JAL Nov 24 '16 at 14:54
  • OS is Linux. But I haven't access to OS. – Hari Seldon Nov 24 '16 at 15:00

You'll need to get access to the OS to run your code to dump the RAM (could be as simple as dd if=/dev/mem of=/tmp/ramdump). There may be hardware workarounds to get the data directly from the RAM chips or logic traces but they likely involve multi-K$ professional logic analyzers or testing tools. In any case, you gave us too little information for a really useful answer.
