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.
The debugger's default behavior is to stop on all exceptions except for C++ exceptions.
Message Abbreviations
The following table describes the meaning of abbreviations commonly found in exception handling messages
| Abbreviation | Meaning | Description |
|---|---|---|
| PC | Program Counter | Instruction pointer at the time of fault. |
| RA | Return Address | Current return address, which points to some offset in caller function. Useful when PC is corrupted and stack trace is not valid. |
| BVA | Bad Virtual Address | Indicates the Virtual Address being accessed which resulted in fault. |
| AKY | Access Keys | Used by thread to access memory amd handles. |
| FSR | Fault Status Register | Fault Status Register 7 indicates a Page/Address Translation error. |
