Can you describe the method you use to do this? Our process is a bit cumbersome, involving putting a breakpoint in a driver's ioctl() function that will only be called by our application. Once it is hit, we use add-symbol-file to get the information for our application's binary, and we are able to proceed. This is on a PowerPC chip, with the special "BDI2000 support" hack turned-on. Is your method any "cleaner"? Thanks, John -- John W. Linville LVL7 Systems, Inc.
