• Tested on VisionFive2 boards w/ "Headless" IoT profile. Expanding coverage to "Headed" IoT profile.
  • It will require .NET support to cover general "Consumer Electronics"
  • Samsung will test w/ an actual RISC-V based CE SoC and actual product next year, which will be a test basis for a few RISC-V extensions, too. (23'12: Started.)
  • Mostly working on unpopular open source packages (packages interested by Tizen only, usually components for consumer electronics, or .NET libraries)

Reference Board for Testing

  • 2023: VisionFive2
  • 2024: A new board with a RISC-V chip with more extension supports and various HW IPs.
