Hi, I have X88 Pro 13 hardware revision 1.7 and tested both Armbian releases v0.6 and v0.7 from the repository. Unfortunately, neither WiFi nor USB 3.0 are working. Hardware info: Device: X88 Pro 13 (Rev 1.7) WiFi chip: AIC8800 (device ID 0x6621, SDIO) Tested images: v0.6 and v0.7 What I tried: USB 3.0: DTB already has maximum-speed = "super-speed" configured USB 3.0 controller exists (Bus 002, 5000M) But only USB 2.0 PHY available (usb2-phy only, no usb3-phy) All USB devices connect to Bus 001/003 (480M) instead of Bus 002 USB Ethernet adapter limited to 100 Mbps Result: USB 3.0 not functional (no PHY in RK3528?) WiFi (AIC8800): Firmware present in /lib/firmware/aic8800/ Drivers load: aic8800_bsp_sdio, aic8800_fdrv_sdio SDIO device detected: mmc2:0001:1, device 0x6621 Error: aicbsp_platform_power_on fails with "fail to set AIC_WIFI power state to 1" No wlan0 interface appears Tried manual GPIO reset (GPIO1_6 = pin 38) - no effect WiFi (EA6621q/SKW drivers): Applied DTB patches from user 8lall0 (GPIO remapping for seekwcn_boot) Built ea6621q DKMS drivers successfully DTB patches verified correct: gpio_chip_en = GPIO1_6 Error: Kernel segmentation fault when loading/unloading SKW modules SDIO scan timeout: "wait scan card time out" Current status: ✅ Armbian boots successfully from SD card ✅ Ethernet via USB adapter works (100 Mbps) ❌ WiFi not working (power-on failure) ❌ USB 3.0 not working (no PHY available) Questions: Is Rev 1.7 supported? Are there different GPIO configurations needed? Does RK3528 actually have USB 3.0 PHY or only controller? Any suggestions for WiFi power issue with AIC8800? Thanks for any help!
