Software package management   

In the Software package management app, the SUMS OEM Manager performs the following activities:

1. Identification: identify the targets (vehicles) by selecting the associated vehicle type, variant, and version and contents of the software update package—specify which are the ECUs that must be updated and mark them if the update includes regulations that are type-approval relevant
2. Assembly: assemble the software update package containing the necessary software, parameters, and metadata for the targets
3. Verification and validation: verify and validate the software update package
4. Release: obtain approval and release the software update package.

Create Software Package #

From the Software packages tab, you can use the Create function to create a software package. This marks the first step and is also referred to as the identification step in which the following are identified: the target vehicle type, the contents of the software package, the purpose, and the ECUs and regulations that are affected.

1. In the Software Update Management System app, from the left navigation pane, in the Software package management section > click Software packages. The Software Packages page is displayed.
   
2. Click Create software package. The Create page is displayed. Select a vehicle type for which the software package is being created.
   
   The list of ECUs associated with the selected vehicle type is displayed.
   

   NOTE:

   You must create a software package against a vehicle type.

3. Select the checkboxes to specify which of the ECUs for this software package will undergo updates for this release.
   

   NOTE:

   In case the software package is being released for a new vehicle type that is being launched for the first time, click the <n> Items checkbox to select all the ECUs.
   For the first release, all the associated regulations are to be selected.

   
4. Click Create. A confirmation dialog is displayed.
   
5. Click Create to confirm. A software package created for the vehicle type is listed on the Software Packages page.
   
   Available columns

Column	Description
Release	Name and version number of the software package
Vehicle Type	Name of the vehicle type for which the software package is created
Status	Software package release state, which could be one of the following: Created, Ready for test, Ready for release, Released, and Rejected. NOTE: Software update refers to a package used to upgrade software to a new version. A version can be created by tweaking a few parameters, for example, for minute level controls, mileage parameters can be finetuned, Rejected’ as a release state is not implemented yet.
Type approval relevance	For a given release, if a regulation is selected for an ECU for which there is a software update, and if this software update contains a code that can cause an impact on the relevant software functionality, it becomes a regulation-relevant change. NOTE: If the type approval relevance is ‘Yes’, it implies that at least one regulation is selected for the software update that can cause an impact on the relevant software functionality.
Created date	Date and time stamp indicating when the software package was created
