Altera cyclone 5 cache awareness

Hi everybody,
I’m trying to debug memory caches on the Altera cyclone 5 board, in particular on Terasic de0-nano-SoC. I’m using ARM DS-5 Ultimate Edition and the linux kernel running on my board is Linux socfpga 3.13.0-00298-g3c7cbb9-dirty. The big issue is that I cannot see cache memories in the debugger! The Data cache view is empty and the cache list comand returns No cache awareness for core “Cortex A9_0”.

I’m fairly sure that the caches (L1 and L2) are provided by the hardware.
How can I resolve this??

Thanks.
BR,

HI!!
Bad news!! I think, cache debug doesnt work for CortexA9! :pensive:
Check the arm doc!
Look at the note on http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.swdev.ds5/index.html
"Note:Cache awareness is dependent on the exact device and connection method."

bye
please write back if I’m wrong!
