GDB: Watchpoint a fixed address.

Question

For my current embedded application I am trying to put GDB watch point at a fixed memory address.

As an example, my application updates the following address: 0x10793ad0. In order to be sure which part of the code is corrupting the value, I tried

watch 0x10793ad0

Even though GDB does not print any error after this, it is not able to break during execution even though I verified the value is getting modified at between start and end of execution.

Questions:

a) Can I really put watch at a fixed address? I didn't come across any such example online. b) Is this the right way or am I missing something?

Answer 1

The right way to set watchpoint on address is watch *0x10793ad0. See gdb doc
