I'm trying to fix problems related to Dcache enabling on Cortex-A9 based board.
Is it possible to inspect cache line data? How I should do it? Shall I use CP14?
I do know that with Lauterbach's TRACE32 it was possible to modify and inspect cache content on the
Cortex-A8 core.
However, such functionality is not available on my Cortex-A9 core. Any hint would be more than welcome.
Thanks in advance,
Łukasz
Łukasz,
Unfortunately there is no such functionality on the Cortex-A9 nor for the L2C-310 cache usually connected to it. The ability to inspect the contents of caches is an implementation-defined feature in ARM Architecture, and even the ones that ARM designs have varying functionality. This has been discussed before.
Ta,
Matt
