Subject: hbreak reads memory
Date: Wed, 27 Jul 2016 06:29:00 -0000	[thread overview]
Message-ID: <VI1PR0401MB2671E54864682705BFABFC6BF10F0@VI1PR0401MB2671.eurprd04.prod.outlook.com> (raw)

Hi everyone,

I noticed that setting a hardware break using hbreak will trigger a memory access at the address where the breakpoint is supposed to be installed. Can someone explain why is that memory access needed? I'm thinking that we might be in a situation where that memory area is not yet initialized/accessible (maybe MMU not configured yet) and the access corrupts the debugged target.

Thanks,
Adrian
