From 68101e67ac16bdead3bd6d48cbe0a2bfd63aac02 Mon Sep 17 00:00:00 2001 From: Paul Fertser Date: Mon, 20 Apr 2015 00:29:37 +0300 Subject: [PATCH] target/cortex_a: examination should be done every time it's asked for It was observed on AM437x that after every reset the target's debug regions are unpowered. To be able to properly communicate with the target and perform cortex_a init debug access after a reset event the examination need to be performed every time, not just on OpenOCD start.
