µVISION DEBUGGER: Adding Third-party DLL Support In TOOLS.INI

Information in this article applies to:

• µVision Version 2.20a and later

QUESTION

I want to add support for the Cygnal 8051F JTAG debugger. I see all the other chip debugger DLL's in the \Keil\C51\BIN subdirectory. I put my Cygnal debugger in the \BIN\ directory but can not get it to run. What am I doing wrong?

ANSWER

The Cygnal DLL must be added to the TOOLS.INI file found in the \KEIL\ folder. To add third-party or custom debugger DLL support to this file you must:

1. Add the DLL to the \KEIL\C51\BIN subdirectory.
2. Add the driver to the TOOLS.INI file. Locate the [C51] section and add the Cygnal driver to the list. For example:

   TDRV0=BIN\MON51.DLL ("Keil Monitor-51 Driver")
   TDRV1=BIN\ISD51.DLL ("Keil ISD51 In-System Debugger")
   TDRV2=BIN\CYGC8051F.DLL ("Cygnal 8051F Driver")
