Apr 1, 2025April 2025 highlights: Completed cross-subsystem firmware bringups and integration across VCFRONT, VCPDU, and VCREAR, enabling pedal monitoring, vehicle state control, and a baseline output-driver stack with TPS20xx usage. Strengthened maintainability with Module Manager cleanup/reorder, added a generic shared HSD driver and software fuse library, and fixed a YAMCAN RX signal bus issue. These efforts deliver end-to-end capability and lay groundwork for more reliable vehicle control software.
