22 Append string to debugger script file, create file if needed.
24 This library can show up in multiple places so we need to append the file every time we write to it.
25 For example Sec can use this to load the DXE core, and the DXE core would use this to load all the
26 other modules. So we have two instances of the library in the system.
28 @param Buffer Buffer to write to file.
29 @param Length Length of Buffer in bytes.
37 // Working around and issue with the code that is commented out. For now send it to the console.
38 // You can copy the console into a file and source the file as a script and you get symbols.
39 // This gets you all the symbols except for SEC. To get SEC symbols you need to copy the
40 // debug print in the SEC into the debugger manually
41 SemihostWriteString (Buffer
);
44 I'm currently having issues with this code crashing the debugger. Seems like it should work.
