µVISION DEBUGGER: DISPLAYING RTX KERNEL VIEWER

Information in this knowledgebase article applies to:

• MDK-ARM V4.12

SYMPTOM

Attempting to display RTX task information in the debugger (Debug — OS Support — RTX Kernel) causes the debugger to crash.

CAUSE

This will happen if the RTOS1= parameter in the Tools.ini file is not set properly during installation.

RESOLUTION

To correct this, do the following:

1. Close all instances of µVision.
2. Using a text editor, open the Tools.ini file located in your installation folder (Default installation folder is: C:\Keil\).
3. Within the [ARMADS] section, find the line that starts with RTOS1=, and make sure it reads as follows:

   RTOS1=VARTXARM.DLL ("RTX Kernel - Viewer")
   

4. If there is a [KARM] section, make the same change within that section.
5. Save the Tools.ini file.
6. Restart µVision.

STATUS

This will be corrected in the next MDK-ARM release.
