Publish a Pack

There are multiple ways to distribute a Software Pack:

# Local Installation

The easiest way to distribute a Software Pack is attaching it to an email or using other means of electronic distribution (for example using a company internal file server). The installation of a Software Pack is usually triggered by double-clicking the PACK file. The Pack management tool is invoked and the Pack is installed on the local machine. After installation, the Pack will be shown in the list of installed Packs (tool dependant). If the PDSC file does not contain a valid `<url>` element, a manual installation is required to update a Software Pack. Otherwise, Pack management tools can check for updates on the server that is specified by `<url>`.

Local installation and update from URL

# Web Download

Any web server can be used to host a Software Pack (specified by the `<url>` element in the PDSC file). At this location, at least two files need to be present (refer to Pack Conventions):

1. <vendor>.<name>.pdsc
2. <vendor>.<name>.<version>.pack, where <version> refers to the latest version specified in the PDSC file.

All previous versions listed in the <releases> section of the PDSC file should be present in that folder as well. This will enable customers to revert updates or to be able to download a specific version of a Software Pack (for code maintenance purposes for example).

Depending on the Pack management tool, a Pack Index Server might be in place that gathers information about published Packs in an index file. This information is then used in the management tool to retrieve version information and to trigger updates of Packs within the development environment.

Note
  - If the URL or the PDSC/PACK files become unavailable (temporarily or permanently), users will not be able to retrieve updates.
  - Do not replace PDSC/PACK files without updating the version number because the Pack management tools will not recognize the update unless the version has been changed.
  - Older PACKs should remain available.

# Publishing on www.keil.com/pack

ARM tries to maintain a list of all available Software Packs. If a Software Pack is intended to be on that list, its PDSC file needs to be sent to to the following email address: cmsis.nosp@m.@arm.nosp@m..com. The PDSC file will be manually XML validated. The following content will be processed in order to generate the web site and index file (www.keil.com/pack/index.idx):

- Version
- Release Notes
- Devices
- Boards
- Examples
- Software Components

Please allow up to seven working days for the process. If the file contains any errors, you will be notified. Otherwise, it will be uploaded to www.keil.com/pack.
