Under the debug menu there is "attach to process", then from the resultant dialog box I select the "secmain.exe" image.
So maybe we need: 1. Open the source file in VS 2. Press F9 to set a breakpoint 3. Run 'build run' in the dos box 4. Attach the debugger to the running process from 3 above. -----Original Message----- From: Jordan Justen [mailto:jljus...@gmail.com] Sent: Friday, December 13, 2013 2:01 PM To: Carsey, Jaben Cc: Amit Kulkarni; edk2-devel@lists.sourceforge.net Subject: Re: [edk2] How to debug application running in secmain with WinDbg/VS2010 Importance: High On Fri, Dec 13, 2013 at 1:47 PM, Carsey, Jaben <jaben.car...@intel.com> wrote: > In visual studio, you can press F9 and get a breakpoint on the line of > code you cursor is on... that way there is no "special" code to > add/remove... Right, but normally when you run 'build run' it is outside of VS, so how do you get VS to debug SecMain.exe? I didn't think VS could set a breakpoint on a line until it was debugging the process, or had somehow associated the code with a particular executable that it expected to debug. Anyway, the CpuBreakpoint was one way I knew to force it into the debugger. It does seem likely that a more elegant solution exists. :) I guess you are saying it is as simple as: 1. Open the source file in VS 2. Press F9 to set a breakpoint 3.
