The ArcCore team has added support for HCS12 to Arctic Core – the open source embedded platform built on AUTOSAR. The release is currently included in Arctic Core _arc_ repository.
The HCS12 support includes a complete port of OS and we will continue selecting a proper reference board and add support for drivers. More about the HCS12 support can be found here.
Arctic Studio – the embedded development tools set – can be updated to support HCS12 (more about this here). Support for HCS12 in Arctic Studio BSW Builder will be available in the next BSW Builder release – planned in Beta version end of March.
