@jock, but wifi was working with original firmware. Doesn't it implies that there is a kernel that can correctly start wifi?

Hello, @jock After a bit of researching i found out that actually rockchip devices initialize wifi in rfkill and there are even some special drivers in kernel for it. I studied a source code of rfkill and saw there hardcoded names of device tree properties that are present in original device tree. There is armbian/linux-rockchip repository where those drivers are present. Maybe that's somehow could help with my case? Does your kernel image have them? Or is it dead end too? Best regards)

@jock, maybe we should take a pause and get back to it later? no signs of wifi chip, log attached rk3328log

@jock, here is the new one similar errors - http://ix.io/4BoF sorry for bothering you upd: added a new full log file( pasted file seems to be not full) devicelog2

@jock, here is another log https://pastebin.com/pGU6rLah Here are errors: 3957 [ 2.804106] mmc_host mmc4: Bus speed (slot 0) = 50000000Hz (slot req 50000000Hz, actual 50000000HZ div = 0) 3958 [ 2.804204] mmc4: error -84 whilst initialising SDIO card 3959 [ 2.804404] dwmmc_rockchip ff5f0000.mmc: card claims to support voltages below defined range 3960 [ 2.808379] mmc4: error -110 whilst initialising MMC card 3961 [ 2.831332] mmc_host mmc4: Bus speed (slot 0) = 300000Hz (slot req 300000Hz, actual 300000HZ div = 0)

Hello, @jock Here is new log(with no wifi) https://pastebin.com/GrTWVfWu(last boot in the end)

@jock, here is my debug log - http://ix.io/4AOO It contains few last boots of system so led-conf5 and led-conf5-alt overlay are included. Wifi still not working

@jock, thank you for overlays. I was busy yesterday, i will try your overlays and get back to you with feedback as soon as possible .

Hello, all Problem: WIFI and Bluetooth is not working on my board with Armbian installed on it Details: I have following TV Box(Photos in spoiler) It has: CPU - RK3328 WIFI + Bluetooth - AP6330 RAM - 1GB SKHynix eMMC - 8Gb Samsung Originally installed OS - Android 7.1 Managed to backup original firmware using rkdeveloptool(but image seems to be broken, anyway that was not an obstacle to extract original dtb, also recovered a lot of files using testdisk utility) I installed following Armbian image on it - Armbian_22.08.0-trunk_Rk3318-box_jammy_edge_5.18.14_kde-plasma_desktop.img. It boots, seems to work ok, but Wifi and Bluetooth is not working. Things I tried that didn't work: Run rk3318-config and choose appropriate device specs Only thing that was fixed using this utility is LEDs Manually choosing overlay rockchip-rk3318-with-wlan-ap6330.dtbo Writing this overlay in armbianEnv.txt didn't help to detect my wifi chip. Folder /sys/bus/sdio stays empty I didn't find anything useful in dmesg output because bcrmfmac kernel module is not loaded at all. When I load it manually only line in dmesg i get is [ 3.841829] usbcore: registered new interface driver brcmfmac So seems that kernel doesn't know anything about WIFI chip. Extracted dtb files in dts format are in attachments. They are almost the same except of two differences(but they where in original img so i decided to keep them) Could please someone look if it worth efforts to do something with it or should i just leave this board as is? rk3328.dts rk3328_1.dts
