Exception Handling Messages (Windows Embedded CE 6.0)
1/5/2010
The following table shows some of the exceptions that the kernel debugger can handle.
| Exception | Microprocessor exception | Description |
|---|---|---|
STATUS_DATATYPE_MISALIGNMENT |
MIPS: 4, 5 SH3: 0x0e0, 0x100 |
An address is unaligned. Verify that all data references are aligned and that the process is in the correct mode, either User or Kernel. |
STATUS_ACCESS_VIOLATION |
MIPS: 1, 2, 3 SH3: 0x40, 0x60, 0xa0, 0xc0 |
An attempt was made to access data through an invalid pointer or you do not have permission to access the object to which the pointer refers. |
STATUS_BREAKPOINT |
MIPS: 9 SH3: 0x160 |
A breakpoint was generated by a call to the DebugBreak function. |
STATUS_ILLEGAL_INSTRUCTION |
MIPS: 10 SH3: 0x180, 0x1a0 |
The microprocessor tried to execute an unknown instruction or an instruction that is invalid in a delay slot. This exception is only encountered if you are writing assembly language code. |
STATUS_INVALID_DISPOSITION |
NA |
The structured exception handler code called a handler to handle an exception, but the handler returned an erroneous or unknown disposition. |
Note
Using try{...} catch(){...} causes an error message to be displayed, stating that the -GX options must be set. Starting with Windows CE 5.0, C++ Exception Handling is supported.
Use the Exceptions dialog box to control how the debugger handles exceptions. The Exceptions dialog box displays system-defined and user-defined exceptions and their actions for your project.
By default, the debugger stops on all exceptions except for C++ exceptions.
