About templates and firmware files

The debug hardware unit stores templates for each supported device. Each template defines how to communicate with the device and the settings that you can configure for that device. The templates ar provided in a firmware file.

ARM periodically releases updates and patches to the firmware that is installed on a debug hardware unit. Each update or patch is released as a firmware file. The firmware filename has the following syntax:

ARM-RVI-N.n.p-bld-type.unit

where:

N.n.p

is the version of the firmware. For example, 4.2.0 is the first release of firmware version 4.2.

build

is a build number.

type

is either:

base

the first release of the firmware for vesion N.n

patch

updates to the corresponding N.n release of the firmware.

unit

identifies the debug hardware unit, and is one of:

  • dstream for a DSTREAM debug and trace unit

  • rvi for an RVI debug unit.

For example, patch 10 for DSTREAM firmware v4.2 is in the file:

ARM-RVI-4.2.10-10-patch.dstream

These might extend the capabilities of your debug hardware, or might fix an issue that has become apparent.
