/package/devices element

The level <devices> contains all devices for which support is provided by the Software Pack.

Devices can be organized in hierarchy groups to limit redundancy. The hierarchy levels are:

  • family: the attributes of a device family which includes also the processor.
  • subFamily: attributes of an optional sub-family; this adds or modifies features of a family.

Device characteristics can be defined in:

  • device: attributes of a specific silicon device
  • variant: attributes of a device variant (for example, with different package or temperature range) or an OEM device or board that integrates the device.

A device is described by the following properties:

  • description: textual device description
  • feature: categorized list of device peripherals and features
  • book: documentation about the device and its processor(s)
  • processor: processor and processor features embedded in the device
  • compile: device specific general settings for the build tools
  • debugconfig: default settings for a debug connection
  • debugvars: global debug access variables for use in sequences.
  • sequences: debug access sequences.
  • debugport: debug port description of the device for the debugger to configure a debug connection.
  • debug: device specific information for the debugger to configure a debug connection including System View Description files.
  • trace: device specific information for the debugger to configure trace.
  • memory: memory layout of the device for internal and external RAM and ROM regions
  • algorithm: device specific Flash programming algorithms

A device will inherit the specifications from both the family and sub-family levels. Some properties are required to be unique. For example, the name of the svd file attribute of the <debug> property. Therefore, the svd file specified on the family level can be redefined by the attribute on the sub-family or device level. Information like the description and feature entries are concatenated, starting with the information from the family and sub-family level and finalizing with the information on the device level.
