@sicxnull I ran into the same issue when flashing "Armbian-unofficial_26.02.0-trunk_Mxqpro_bookworm_current_6.12.65_minimal" (worked only in SD Card). The issue was gone when I switched to "Armbian-unofficial_25.05.0-trunk_X96q-lpddr3-v1-3_bookworm_edge_6.12.11_server" built by @Nick A

While reviewing the system logs, I noticed several ftrace warnings appearing in dmesg. After investigating the root cause, I have applied the necessary configuration updates to eliminate these logs. The driver is now running cleanly without any ftrace-related noise.

@Nick A Yes, I used the MT7601U for a few days, but I wasn’t really satisfied with it. So, with the help of AI, I decided to port the SV6256P anyway—and to my surprise, it actually worked.

@jock The driver-related knowledge is vast and quite complicated, with many pitfalls, so porting really requires strong assistance from AI. I don’t have an SSV6051, so I can’t actually complete the porting myself. Btw, the "ssv6x5x-sw.bin" I’m using is the file you posted on the forum.

I’m really happy to share that I finally managed to port the SV6256P (SSV6X5X) SDIO Wi-Fi driver from the legacy Linux 4.4 kernel to modern kernels. This repository contains my working port for Linux kernel 6.12 and newer, with updated mac80211/cfg80211 integration so the driver can build and run on recent Armbian systems. The chipset is commonly used in many low-cost TV boxes and embedded devices, but the original driver only supported legacy kernels (4.4). Now it’s functional again on modern systems, at least on my tested hardware (Allwinner H616 / X96 Q via SDIO). Repository link: https://github.com/cdhigh/armbian_sv6256p I’m quite excited to finally see this old Wi-Fi chip working on a 6.x kernel 🙂 [ 4.774151] ssv6x5x: importing configuration from /lib/firmware/ssv6x5x-wifi.cfg [ 4.778281] tu_ssv6xxx_sdio_init, probe @(____ptrval____) [ 4.779483] TU_SSV6XXX_SDIO mmc3:0001:1: Probing SDIO bus [ 4.779513] ssv6xxx_set_sdio_clk: set sdio clk 25000000Hz [ 4.799668] TU_SSV6XXX_SDIO mmc3:0001:1: vendor = 0x3030 device = 0x3030 [ 4.825421] TU_SSV6XXX_SDIO mmc3:0001:1: dataIOPort 0x10000 regIOPort 0x10020 [ 4.849181] TU_SSV6XXX_SDIO mmc3:0001:1: dataIOPort 0x10000 regIOPort 0x10020 [ 4.849530] TU_SSV6XXX_SDIO mmc3:0001:1: CHIP ID: SSV6006C0 [ 4.850373] ssv6x5x ops chk: tx=1 start=1 stop=1 config=1 add_if=1 rm_if=1 conf_filter=1 wake_txq=1 [ 4.850402] ssv6x5x chanctx chk: any=1 all=0 emulate=1 add=1 rm=1 chg=1 assign=0 unassign=0 [ 4.850409] ssv6x5x chanctx ops set but not complete [ 4.850424] Attach SSV6006 family HAL function [ 4.858285] MAC address from e-fuse [ 4.858311] EFUSE configuration [ 4.858315] Read efuse chip identity[79000000] ip link show: 6: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DORMANT group default qlen 1000 link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff

@Nick A Thank you for your excellent work! I managed to compile it myself and shared it with someone who has the same board (IK316-EMCP_V1.0). 1. Changed kernel preemption mode from full preemption to voluntary preemption. 2. Added MediaTek Wi-Fi drivers (MT7601U etc). 3. Embedded kernel headers. https://github.com/cdhigh/armbian_build/releases/tag/v20250306

@Nick A I agree with your point — for modern SBCs, the difference is probably not that significant, and it’s more of a psychological feeling. However, it would be even better if the new version could switch to CONFIG_PREEMPT_VOLUNTARY.

@Nick A Thanks for the reply. I don’t have enough Linux knowledge, so should I just wait for your new release? My box isn’t an X96Q — it’s a generic no-name one — but after trying many, many images, I found that the version you compiled happens to work perfectly and runs smoothly. So far I haven’t found any issues (the only thing missing is Wi-Fi, but that’s not a problem with your build: SV6256P). Even other images made for X96Q LPDDR3 by different people have all kinds of problems. Another small issue: your current compilation option is fully preemptive scheduling. This option is not suitable for server use. I suggest changing it to voluntary preemption or non-preemptive, thank you. The option of your images: CONFIG_PREEMPT_BUILD=y # CONFIG_PREEMPT_NONE is not set # CONFIG_PREEMPT_VOLUNTARY is not set CONFIG_PREEMPT=y # CONFIG_PREEMPT_RT is not set CONFIG_PREEMPT_COUNT=y CONFIG_PREEMPTION=y # CONFIG_PREEMPT_DYNAMIC is not set # CONFIG_SCHED_CORE is not set # CONFIG_SCHED_CLASS_EXT is not set

@Nick A Could you create a current version image? I’ve tested all the images I could find, and only yours runs perfectly. Armbian-unofficial_25.05.0-trunk_X96q-lpddr3-v1-3_bookworm_edge_6.12.11_server.img.xz However, since this is an "edge" build, it doesn’t include MT7601U wifi card support, while the current version does. I tried compiling it myself, but ran into many errors and couldn’t complete the build. If you could create a "current" branch image, that would be ideal. Thanks in advance!
