I have one question regarding the cortex-A15 core of AM5728.
My customer measured the two types performances with AM5728. One is A15 single core. And other one is A15 dual core.
According to the measurement results, dual core performance is lower than single core performance. Because, when AM5728 runs with dual core, main core generates the interrupt to sub core frequently. So dual core performance is lower than single core working.
Do you know why this situation is happenning? OS is Windows embedded compact.
Please advise me.
I appreciate your quick reply.

In reply to Biser Gatchev-XID:
I would like AM5728 to work as single core device, not dual core on linux SDK.
For single core action, to remove the check of Symmetric Multi-Processing is needed, I think.
Is my understanding right? or is other action needed?
I failed to attach the needed picture in my previous post.
