# RSL15 CMSIS-Pack Installation Procedure

1. Extract the RSL15 Firmware package to a temporary folder.
2. Create a new workspace at, for example, C:\workspace, using the onsemi Launcher, by following these steps:
   1. Open the onsemi IDE by going to the Windows Start menu and selecting onsemi > onsemi IDE.
   2. From the onsemi IDE Launcher screen, edit the suggested workspace name to a new name if needed, and click Launch.

NOTE: We recommend creating a new workspace for each new version of the IDE to ensure compatibility.

3. On the top row of the Workbench perspective, click the "Make the CMSIS Packs manager perspective visible" icon. (See the "Opening the CMSIS-Pack Manager Perspective" figure.)

NOTE: If you have trouble opening the CMSIS-Pack manager perspective, re-install the IDE in your user folder (i.e., C:\Users\<user_name>).

4. Click the Import Existing Packs icon, select your pack file (ONSemiconductor.RSL15.<version>.pack), where <version> is a number such as 1.0.0-464, and click Open. (See the "Installing the RSL15 CMSIS-Pack" figure.)

NOTE: If this is the first time an onsemi CMSIS-Pack is being installed on your system, you are likely to see the following error message:
The CMSIS-Pack root folder "C:/Users/<user_id>/AppData/Local/Arm/Packs" is empty. Please import the CMSIS-Pack.
To resolve this, click the icon shown in the "Reload Packs in the CMSIS-Pack root folder" figure.

NOTE: The default CMSIS-Pack location is:
C:\Users\<user_id>\AppData\Local\Arm\Packs\ONSemiconductor\RSL15\<version>\
where <user_id> is your userid on your system, and <version> is the RSL15 version number.

5. The RSL15 CMSIS-Pack now appears in the list of installed packs. In the Devices tab, if you expand All Devices > ONSemiconductor > RSL15 Series, you can see RSL15 listed there. You can manage your installed packs in the Packs tab. Expanding ONSemiconductor > RSL15 and selecting the device makes the Pack Properties tab display the details of the RSL15 CMSIS-Pack (see the "Pack Manager Perspective after RSL15 CMSIS-Pack is Installed" figure). Selecting the device in the Devices tab also displays the RSL15 information in Pack Properties.
