Subject: cortex a8: only physical read/write's are available when target is
running
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Memory read/writes to virtual memory, requires that the CPU is
halted.
Use 'phys' option to write to memory while target is running.
