Adapting the FCS950U (UWE5622) SDIO Wi-Fi Module on the OK3576-C Platform

Porting wireless modules to modern Android GKI architectures often brings roadblocks—hashtag#SDIO recognition failures, missing interface nodes, and DLKM driver loading errors.

Our latest technical guide covers the end-to-end adaptation of the FCS950U (UNISOC UWE5622) SDIO Wi-Fi + Bluetooth combo module onto the Forlinx OK3576-C (Rockchip RK3576) running Android 14 (Linux 6.1).

What this guide covers:
Hardware & DTS: Power timing compliance, SDIO 4-bit interface setup, and Device Tree nodes.

Kernel & GKI: Linux 6.1 driver porting, Vendor DLKM packaging, and firmware deployment.

Android Layer: HAL adaptation, wpa_supplicant tuning, and STA / SoftAP / Wi-Fi Direct verification.
