gk7202v300: no ultimate build available + RTL8188FTV (0bda:f179) WiFi not working in lite build

[KoenD96]

Summary

Two related issues affect the GK7202V300 platform with an RTL8188FTV USB WiFi module:

1. No ultimate build is published for gk7202v300
2. The lite build does not include the 8188fu driver or firmware blob needed for RTL8188FTV

Hardware

• SoC: Goke GK7202V300 (RNCSV300 D1FF AA)
• Flash: XMC 25QH128CHIQ (16MB NOR)
• WiFi module: Realtek RTL8188FTV via USB (USB ID 0bda:f179)
• Board: BM002-IPC-GK7202-PCB-V10-20231012A
• WiFi board: BL-M8188FU3 (Realtek 8188FTV daughterboard)

Firmware tested

• openipc.gk7202v300-nor-lite.tgz (nightly 2026-05-26, BUILD_SHA=85babed)
• Stable build from: https://openipc.org/cameras/vendors/goke/socs/gk7202v300/download_full_image?flash_size=16&flash_type=nor&fw_release=lite
• No openipc.gk7202v300-nor-ultimate.tgz exists among the releases, however it appears in the drop down menu in the Installation Guide generator

Issue 1: No ultimate build for gk7202v300

Checking the nightly releases page, only a lite variant is published for gk7202v300.
Other platforms (e.g. gk7205v200) have both lite and ultimate builds.
Is the ultimate build needed to include WiFi drivers like kmod-rtl8188fu?

Issue 2: RTL8188FTV not working

With the lite build:

• lsusb correctly detects the module as 0bda:f179
• No 8188fu.ko exists anywhere in /lib/modules/4.9.37/
• Only r8188eu.ko is present, which does not support USB ID f179
• /lib/firmware/rtlwifi/ does not exist

This is related to issue #1906 (same root cause on HI3518EV200) where
BR2_PACKAGE_RTL8188FU_OPENIPC=y is set but the firmware blob is misplaced.

Expected behaviour

• An ultimate build should be available for gk7202v300-nor (16MB flash)
• Or both builds should include 8188fu.ko and rtl8188fufw.bin in the correct locations
• WiFi should work out of the box with fw_setenv wlandev rtl8188fu-generic

Workaround attempted

None successful without internet access on the device.
The r8188eu.ko staging driver does not bind to 0bda:f179.
