I want to set in IDA breakpoint when a specific value is written on the stack.

I know how to set hardware breakpoint, but I can set it only by address.

You simply cannot. There are no mechanisms by which you can break execution on a specific value write. You'll have to use any other mechanisms, probably a memory breakpoint, and a conditional check of what's at the top of the stack.

  • That'd be slow, but you can set a conditional memory breakpoint in IDA on stack pages.
