Error Handling in WinKFPT
The process of flash programming an ECU with WinKFPT is very complex and depends on trouble-free interaction of the following components:

· Hardware connection – Test computer Ö Diagnosis HW interface Ö ECU

· Software connection – WinKFPT Ö EDIABAS Ö Diagnose interface driver Ö ECU program

· Configuration of WinKFPT and COAPI

· Description files PABD and P-SGBD

· Logistics files

· Programming data files (PAF, DAF, etc.)



Each component contains a multitude of potential errors that must be trapped by WinKFPT and displayed to the user in a manner that enables him to recognize the cause from the error message displayed and eliminate this cause on his own initiative.



The functions built into WinKFPT can be roughly split into two types: namely, into functions with and without COAPI calls. The manner in which errors that arise while executing these functions differs between the two types.



· Displaying errors in WinKFPT functions without COAPI calls:

Display of informative error, diagnosis and info texts in appropriate message boxes.

The texts are loaded dynamically from the text file "winkfpt.txt". It is possible to improve on the explanatory power/correctness of the texts at any time without making changes to WinKFPT.



· Displaying errors in WinKFPT functions with COAPI calls:

Each time an error occurs when a COAPI function is called, an error dialog is displayed. The top text box in this dialog contains a text that informs you of which active WinKFPT function the error has occurred in. The list box below this contains a detailed list of errors traced through all the COAPI call levels run through.

This error list should not be viewed as a list of different errors, rather as a breakdown of just a single error, with the respective information that has been able to be established from the relevant COAPI call levels.

The COAPI error texts are loaded dynamically from the text file "coapierr.txt".


................................................................
Displaying Errors


The figure below shows the "Normal view" display of a WinKFPT error associated with a defective COAPI call.

Switching to the "Extended view" is of no benefit to "normal" users. This view is intended merely as an additional debugging aid for WinKFPT or COAPI experts.





Fig.: Error display window in WinKFPT

In the example above, you can see that initialization of the COAPI by WinKFPT has failed.

The list of errors from the respective COAPI call levels clearly shows the user which of the many initialization errors possible is the actual cause of the error.

The first line of the error list displays the error message of the "lowest" COAPI call level and generally contains comprehensive and crucial information for debugging purposes.

In this case, the user must check whether the file "KFCONFXX.DA” is present in the <root>\DATA\gdaten directory, or whether or not he has read rights to it.
