Brendan Szymanski 666e8edd5f bcmdhd: set FW_AMPAK_PATH for vendor firmware directory 
Define FW_AMPAK_PATH as vendor/firmware/brcm so the driver's
dhd_conf_add_filepath constructs the correct absolute firmware
path /vendor/firmware/brcm/fw_<chip>.bin.

README.md

Orange Pi 5 Ultra — Kernel Source

Source kernel for the Orange Pi 5 Ultra (Rockchip RK3588). Forked from dvab-sarma/android_kernel_rk_opi (android-16.0-hwaccel-testing branch).

Based on mainline Linux 6.15 with Rockchip DRM patches and Android kernel features (binder, memfd, cgroups, SELinux, etc.).

Device Tree

WiFi (brcmfmac SDIO) and Bluetooth (hci_uart BCM serdev) are enabled in the rk3588-orangepi-5-compact.dtsi shared DT include. PIN mappings follow jimmyhon/linux max-wifi branch:

Function Pin
WIFI_REG_ON GPIO2 PC5
BT_REG_ON (shutdown) GPIO4 PC4
BT device wake GPIO4 PC5
BT host wake GPIO0 PA0
WiFi host wake GPIO0 PB0
SDIO sdiom0_pins
BT UART uart7m0_xfer + ctsn/rtsn

Building

Built via LineageOS's TARGET_KERNEL_SOURCE mechanism. The kernel is compiled by AOSP clang during mka:

TARGET_KERNEL_SOURCE := kernel/rockchip/tart
TARGET_KERNEL_CONFIG := tart_defconfig

Output: Image + rk3588-orangepi-5-ultra.dtb at $(KERNEL_OUT)/arch/arm64/boot/.

Defconfig

tart_defconfig is based on android_orangepi5_defconfig with the same driver set. Key options:

  • CONFIG_DRM_PANFROST — Mali-G610 GPU (Panfrost)
  • CONFIG_BRCMFMAC_SDIO — AP6611S WiFi
  • CONFIG_BT_HCIUART_BCM — SYN43711 Bluetooth
  • CONFIG_R8169 — RTL8125BG 2.5GbE Ethernet
  • CONFIG_SND_SOC_ES8388 — Audio codec

Branch

lineage-23.2 — for use with LineageOS 23.2 (Android 16).
