Hi all



I'm using i.MX6Solo and have a question about ERR005198.

I can't understand the conditions of PL310 internal access request.



According to the errata, there are following description.

I understand the information will be sampled when PL310 requested.


This information is associated with each individual RAM access, and is only meant to be sampled

by the PL310 internal access requestor at precise cycles, depending on the programmable latencies

of the accessed RAM.


What situation will make the PL310 internal access request ?
