Adding System Viewer Windows

System Viewer windows display peripheral register information when debugging an application. The mechanism to display peripheral register information is the peripheral register file. These files are named according to the device or device series they belong to. The files are located in the folder ..\ARM\SFD\vendor\device_series and have the extension *.SFR.

Devices supported by MDK are configured to display the peripheral register information automatically. However, in case the peripheral register file is missing, you can add the file to the Device Database or to the project as described below.

Adding the peripheral register file to the Device Database has the advantage that all future projects based on that device will show the peripheral register information automatically. No further modifications are required.

  1. Add the peripheral register file to the device definition in the µVision Device Database using the parameter SVD. Refer to C. Device Database Parameters.
  2. Add the *.SFR file to the current project as described below.

Adding the peripheral register file to the project amounts to less work, but these steps have to be completed for each new project based on that device (unless the Device Database has been configured).

  1. Open the dialog Options for Target - Target.
  2. Enable Use Custom File and enter the file name into the field System Viewer File.

The *.SFR file is missing in MDK

In case the peripheral register file cannot be found, developers can create *.SFR files with a few steps. Silicon vendors maintain and publish device-specific CMSIS-SVD files, which describe the device peripherals and properties. Developers can process that XML-based file to create an .SFR file.

  1. Download the CMSIS-SVD description file from the CMSIS-SVD web page. Description files could have the suffix *.xml instead of *.svd.
  2. Create the peripheral register file with the System View Description Converter.
  3. Add the peripheral register file to the Device Database or project.

Note

  • Future MDK releases might include the missing System Viewer file in the configuration of the Device Database.
