Error E171

Summary
*** Error E171


AGDI: Unsupported interface function.
Description

An optional AGDI interface function is called but not implemented in the debug driver DLL.

Cause

Either the debug driver DLL reports unimplemented features or the upper software layers of µVision ignore such information.

Resolution

This is an internal error and needs investigation. Please contact Keil support or the debug driver DLL vendor.

In case you have enabled the debug description, try to:

  • Submit the screen shot of Options for Target - Debug - Settings - Pack to support.
  • Disable the use of CMSIS Pack Debug Description in Options for Target - Debug - Settings - Pack.
  • Configure the target manually for debugging.
