µVISION: Loading PDSC Debug Description failed for STM32F7xx


Information in this knowledgebase article applies to:

  • MDK 5
  • STM32F7xx_DFP 2.10.0 and higher
  • STM32H7xx_DFP 2.1.0 and higher

SYMPTOM

After updating the STM32F7xx or STM32H7xx Device Family Pack, you might see the following error message when loading an existing project in µVision:

Loading PDSC Debug Description failed for STMicroelectronics STM32F7...

The Build Output windows looks similar to this screenshot:

CAUSE

The Debug Description for STM32F7xx and STM32H7xx devices was updated and became incompatible to previous versions. This issue appears if you are using a STM32F7xx pack version 2.10.0 (or higher) or STM32H7xx pack version 2.1.0 (or higher) with a µVision project that was created with a previous version of these packs. Debug Description files (*.dbgconf) are automatically copied from the corresponding pack folder to your µVision project folder when a project is created.

RESOLUTION

  • Close your µVision project.
  • Delete all *.dbgconf files in your µVision project folder ProjectFolder\DebugConfig\*.dbgconf.
  • Start µVision and load your project. A Debug Description file *.dbgconf (one per µVision target) will be copied automatically from the latest installed Device Family Pack.
