To get unstuck you just need to update Index to be non Zero. I've also used this technique for JTAG debuggers. For an EFI App I generally use CpuBreakpoint(). The advantage to using getchar() is the "otherwise press enter to continue..." path. So I agree the command line option seems like a reasonable thing to do.</div><div class=""><br class=""></div><div class="">The other trick I played in this area was to have both a `run` and `lldb` option to the script. The `run` option launches the debugger, the 'lldb' (or gdb) option drops you into a debugger prompt so you can set breakpoints early in boot. </div><div class=""><br class=""></div><div class="">Long term maybe we could have a common Python based build commands for both Windows and Unix and at that point we could move to launching via the debugger for all paths?
