The implementation uses the DesignWare Core Dual Role Device (DRD) controller, which supports both USB 2.0 and 3.0 modes via two PHYs: the Inno PHY (shared with USB 2.0) and the new USBDP PHY (combo with DisplayPort Alt mode). In gadget mode, a host machine can recognize the board as a mass storage device or use the Rockchip rkdeveloptool to reflash media. A known limitation is that only one cable orientation works with Type-C to Type-C cables. Patches are publicly available for review and contribution. ## Full article daily.dev links to this article rather than hosting it.
