as I mentioned already, Linux is not really my world...
But of course OMV is worth to work with Linux a bit more in details.
Nevertheless, it is not easy to get info about that "burnCortexA9". It is part of "cpuburn", but "cpuburn" does not belong to the normal packages. So where can i find it?
Next problem, I found cpuburn at github as program code for several Arm-Cores.
There is cpuburn-A9 and cpuburn-A53 available. Of course it has to be compiled first, next problem.
But I got it. Executing cpuburn-A9 starts all 4 A9-cores, while cpuburn-A53 starts all 8 cores (4*A9, 4*A53) of the Exynos5422 .
The script mentioned by dleidert has then to be adapted to 8 cores and (so far) unknown burnCortexA9, which I did not find
Is it possible to get that easier?
