I have a JTAG with xbdm installed and I'm using xdevkit to read and write memory. I can create instruction breakpoints using DebugTarget.SetBreakpoint() which is useful, but I REALLY need a memory breakpoint. DebugTarget.SetDataBreakpoint() is an available function, but it doesn't appear to have any effect? Either that, or some way to trace which addresses read/write to a memory address. Any solutions? Thanks for your time!
