CanMV K230 SDK Release Notes v1.5-legacy
This is a Legacy/Baseline release. It captures the stable state of the CanMV K230 RTOS environment (based on RTOS SDK v0.6 submodules) before a major transition in the codebase.
If your project requires the current workflow and submodule structure, please use this version. Future releases will introduce significant changes that may not be backward compatible.
📌 Release Overview
This version synchronizes all core submodules (rtsmart, mpp, u-boot, etc.) to the rtos-v0.6 milestone, providing a feature-complete environment for AI, media processing, and RTOS development on the K230.

cv_litewith support for corner detection, undistortion, and rectangle drawing. - Networking: Integrated the
mqttclientlibrary for IoT applications. - New Demos: Added AI + RTSP streaming examples and a media pipeline demo for saving encoded video to the small core.
🛠 Stability & Bug Fixes
- Fixed USB CDC 100ms stall and potential kernel crashes during
lsusb. - Optimized I2C transfer reliability and fixed touch screen interrupt handling.
- Improved memory management and task scheduling stability in the RT-Smart kernel.
⚠️ Important Notice for Developers
This version is tagged as legacy because it represents the "end of an era" for the current SDK structure.
