Can I break and trace in the popup window (Start condition) field on a pointer?
Code:
[RSP]==0x00007FF7C89C3D70

Code:
readPointer(RSP)==0x00007FF7C89C3D70


Of course none of them work but is there a way to use them without using the Lua engine? If there isn't could you give me an idea of how to do that using the Lua engine?

It's a LUA expression.

I know it's Lua but could you give me an example?
I've never done that before.

I could track registers' content but never a pointer/address.

This is a valid simple Lua condition for a breakpoint. If it doesn't do what you expect it to, the problem is likely somewhere else. e.g. data breakpoints (write or access) trigger after an instruction has executed, while code breakpoints (execute) trigger before the instruction has executed.

Get more information such as what type of breakpoint you're using (break-and-trace can be used on either code or data), what instruction triggered the breakpoint, the code around that address, and information on the stack (value of RSP and the top few values of the stack) including when and where that information was recorded.
