The Simplicity Studio release that was made on Friday April 26th (SV18.104.22.168) had issues that prevented some Simplicity Studio installations from updating correctly. The installations that would fail were versions SV22.214.171.124 and SV126.96.36.199. If the last time Simplicity Studio was updated was before March 29th (so version SV188.8.131.52 or earlier) then the update worked correctly.
This issue has been resolved with the Simplicity Studio release that was made Tuesday afternoon, April 30th 2019 (UTC-06:00). The version of this release is SV184.108.40.206 (seen from [Help] > [About]). This release will update all versions of Simplicity Studio and it will fix any failed attempts to update to SV220.127.116.11. It will also properly update any installations that had worked around the update issue by manually applying an update to the Simplicity Studio Product package and then applying the other updates.
If Simplicity Studio is configured to automatically check for updates when it starts (the default setting) then the user will automatically be prompted to install the new update after they start or restart Simplicity Studio. If Simplicity Studio is configured to manually or periodically check for updates, then clicking the [Update Software] link will check for updates and then the available updates can be seen from the [Package Manager] [Product Updates] tab.
Depending on when Simplicity Studio was last updated several more updates could be available. To apply all of the available updates click the [Update] button and then after the update completes restart Simplicity Studio.
If any problems are seen with the update, please respond to this Knowledge Base Article or else create a new Simplicity Studio Community Forum thread or support case to report the issue.
Silicon Labs apologizes for the inconvenience this update issue has caused our customers.
Currently if the offline installer archives are used to install and update Simplicity Studio it is hard to tell when the archive files have been updated indicating that an update is available. Since the files tend to be very large (some are over 8 GB) it is inconvenient to download them just to check if they have been updated. So this article will list the latest version of Simplicity Studio and the various SDKs that have been released. The goal will be to update the article each time there is a new release, so that by following this article customers will be notified when Simplicity Studio and the various SDKs have been updated.
I also want to point out that the Simplicity Studio [Help] > [About] functionality has been enhanced to show a unified version number and the versions of the various components that comprise that version of Simplicity Studio. The information is presented in a matrix format that will show the component versions for the last 10 Simplicity Studio releases. The unified version number will make it easier to communicate the installed version of Simplicity Studio to Silicon Labs.
The current version of Simplicity Studio is 18.104.22.168. It was released on November 26th, 2019 and this is a portion of the [Help] > [About] information that also shows the Simplicity Studio Platform version (which was previously the easiest way to report the Simplicity Studio version):
On the About box there is also a "Toolchains and SDKs" tab that shows the versions of the installed toolchains and SDKs. This screenshot shows the information on the latest available SDKs as of November 26th, 2019:
I hope this information proves useful especially to customers using the offline archives files to install and update Simplicity Studio. This article should provide a temporary benefit until an update indication can be added to the offline installer page.
