hbreak reads memory

[Alexandru-Adrian Oltean]

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
