AGDI is an Application Program Interface (API) third-party developers can use to create hardware debugger drivers that interface directly with the Keil µVision Debugger. The purpose of AGDI is to provide a way to interface the Keil Debugger user-interface to a third-party‘s hardware debugging interface.
AGDI drivers are DLLs that are created using Microsoft Visual C++ and template files provided by Keil.
For further information please download Appnote 173 for ARM-based target systems or Appnote 145 for 8051 and C166 based systems.
AGDI drivers can interface to:
#define _EXPO_ __declspec(dllexport) extern _EXPO_ U32 AG_Init (U16 nCode, void *vp); extern _EXPO_ U32 AG_MemAtt (U16 nCode, UL32 nAttr, GADR *pA); extern _EXPO_ U32 AG_BpInfo (U16 nCode, void *vp); extern _EXPO_ AG_BP *AG_BreakFunc (U16 nCode, U16 n1, GADR *pA, AG_BP *pB); extern _EXPO_ U32 AG_HistFunc (U32 nCode, I32 indx, I32 dir, void *vp); extern _EXPO_ U32 AG_GoStep (U16 nCode, U32 nSteps, GADR *pA); extern _EXPO_ U32 AG_Serial (U16 nCode, U32 nSerNo, U32 nMany, void *vp); extern _EXPO_ U32 AG_MemAcc (U16 nCode, UC8 *pB, GADR *pA, UL32 nMany); extern _EXPO_ U32 AG_RegAcc (U16 nCode, U32 nReg, GVAL *pV); extern _EXPO_ U32 AG_AllReg (U16 nCode, void *pR);
All functions that start with AG_ need to be defined in the target driver DLL. If a function executes correctly, the value 0 is returned to µVision, otherwise an error code should be returned. Note that the following exported functions must be defined, either fully functional or just as dummies:
| Function | Description |
|---|---|
| AG_Init() | AGDI Initialize function. |
| AG_MemAtt() | Memory Attribute access function. |
| AG_BpInfo() | Breakpoint Set / Reset / Enable / Disable / Kill function. |
| AG_BreakFunc() | Breakpoint access function. |
| AG_GoStep() | Go / Step / Stop commands. |
| AG_Serial() | Read / Write a Serial Window function. |
| AG_MemAcc() | Access target memory function. |
| AG_RegAcc() | Read / Write a single Register function. |
| AG_AllReg() | Read / Write Registers function. |
| AG_HistFunc() | Trace History access function. |
If this is not the case, µVision considers the target driver as invalid and cancels using it.
AGDI can borrow some of the functionality from µVision. This can be done by using the pCbFunc callback pointer, a function code and the appropriate parameters. Note that only the most important callback functions are described here. The additional ones can be found in AGDI.H near the end of the file.
