Hello, I have a problem of having the PB4.2 to debug my application program. Basically what I did was as follows; 1) Created a new platform with minimum components; i.e. all peripherals/drivers except USB, explorer, command prompt, control panel components, etc. 2) Created a new project (both with and without "HelloWorld" default application program and my own source codes. 3) Set the Platform Settings/Build options to: Enable CE Target Control Support, Enable Eboot Space in Memory, Enable Full Kernel Mode, Enable Kernel Debugger and Enable KITL. 4) Set the Platform Settings/Build type to: Debug, settings for "INTEL DBPXA250 DEV PLATFORM : ARMV4I Win32 (WCE ARM4VI) Debug", and set the release directory to my "C:WINCE420PUBLICXYZPUBLICRelDirINTEL_DBPXA250_DEV_PLATFORMARM4VIDebug". 5) Configured my Remote Connection/Download and Kernel Transport to "Ethernet" and configure the target device. 6) I have also set the "Configurations" and "Set Active Configurations" under "Build" menu all to debug mode. 6) Under Project Setting, I have set all to debug mode too. 7) I have tried 2 methods of setting the breakpoints; [i] I set the breakpoints before building the whole platform. [ii] I set the break after I have downloaded the platform by "Debug" -> "Break" -> insert breakpoints -> "Go" -> run application program. Both methods did not hit the breakpoints. According to the "HELP", I should be able to debug my application program through the Kernel Debugger. However, I could get the program to hit the breakpoints. Could you advise me on how should I solve this. Thank you. Lawrence
