@jock Thank you, I will try.

Hi all, I have an RK3318 TV box (A95X R2_V20). The front panel controller is TM1628. I’m running Armbian 23.11.1 with kernel 6.19.0‑edge‑rockchip64. Problem: tm16xx is not enabled in this kernel (CONFIG_TM16XX_* not set), and there is no rk3318x-config in this image. I tried to locate tm16xx sources in current Armbian kernel trees and mainline, but the driver is missing, so I can’t build it from the local headers. I have active Docker projects (avito-bot) on this box and don’t want to reinstall the system, and previous two reinstalls ended with apt issues, so I’d prefer to avoid a fresh image. Question: Is there a known external tm16xx driver repo (or patch) that can be built as an out‑of‑tree module for RK3318? If yes, could you point me to the source and any required device‑tree overlay/pin mapping for TM1628? I already posted board photos and dtb above (my post is still unanswered), so please refer to that if needed. Thanks!

@jock Thanks. My box is A95X R2 (rk3318), mainboard A95X R2_V20 (2019‑07‑02). Front panel board A95XCX1_IO_V1.0 (2019‑03‑05). The LED controller on the front panel is TM1628 (photo available). So I should use the tm16xx kernel driver (tm1628), not openvfd. I’ll try rk3318x-config to enable the front panel. If the board isn’t in the list, I can provide front/back photos and dtb.

Hi all, I’m trying to enable the front VFD/LED display on an RK3318 TV box. OS: Armbian 23.11.1 Jammy, kernel 6.18.10-current-rockchip64 DTB: rk3318-box.dtb (fdtfile=rockchip/rk3318-box.dtb) In DTB I found: fd628_dev { compatible = "fd628_dev"; fd628_gpio_clk = <0x7a 0x10 0x00>; // bank2, offset16 fd628_gpio_dat = <0x7a 0x0f 0x00>; // bank2, offset15 }; I built linux_openvfd and added an openvfd node in DTB: openvfd { compatible = "open,vfd"; dev_name = "openvfd"; status = "okay"; }; Module loads, /dev/openvfd appears with: vfd_gpio_clk=2,16,0 vfd_gpio_dat=2,15,0 vfd_gpio_stb=2,19,0 vfd_display_type=0,0,0,0 vfd_chars=0,1,2,3,4,5,6 vfd_dot_bits=0,1,2,3,4,5,6,0 dmesg shows: OpenVFD: Select FD628 controller OpenVFD: SPI 3-wire interface initialized (LSB mode) /sys/class/leds/openvfd exists, but no indicators light up. Tried multiple display_type values and STB pins (bank2 offsets 18–22 + other banks) — still no output. Question: Does anyone know the correct GPIO pins (CLK/DAT/STB) for rk3318-box VFD, or a working driver/service for FD628/FD650 on this board? Any confirmed configs for RK3318 boxes would be greatly appreciated. I’ve been working on this for ~2 weeks and tried multiple configs/drivers without success. Thanks!
