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??
