µVISION DEBUGGER: error 65: access violation...: no 'read' permission


Information in this knowledgebase article applies to:

  • MDK-ARM V5
  • Simulation

SYMPTOM

I have build an application with MDK-ARM, but when I the Debugger, which configured as Simulator, I see the error message:

error 65: access violation at 0x40023800 : no 'read' permission

At the Command window I see this error appearing like:

CAUSE

The problem is that the STM32Fx series is not fully simulated and therefore any peripheral access causes an access violation.

RESOLUTION

Use target debugging instead.
