The current S32 SDK available for the S32K144 has been updated since the video was recorded. The video will not likely be updated unless there are significant changes in the SDK or IDE which cause it to not be useful.
If you find any content or videos which are no longer useful due to changes in the tools, please inform us so that we might get them updated.
