Has anyone used it, please give me feedback😀

Can you provide your built image? I never build one before

I try your prebuild image, and no luck with wifi/Bluetooth. My tv box new revision and have YC8800D wifi chip.

Can i do something to get work WiFi?

Tried your image on an SD card but tried several way to get it to boot from SD was unsuccessful. I tried the toothpick on the button inside the 3.5 mm port. I tired ADB reboot update and ADB reboot recovery. But all those times, I just receive the android recovery menu when failed to boot SD.

Is there any thing special I need to do to get this box to boot from SD? I will solder some dupont pins soon so I can get a better reading what is happening with serial console.

But for now, do you know why it is so difficult to boot from SD. I never had this much issue with an AMLogic S9xx before.

How can I tell if bootloader is locked? If locked what options do I have?

More to say

Hello,

I guess this is the right forum for my topic: I have got a T95zplus H618 TVBox with AW869A. People having this box may know, there exist an armbian image by LYU4662 at github: https://github.com/LYU4662/t95zplus-h618-build

However, after installing it, there is no wifi. I did some analysis with claude, it concluded that there are only some small changes necessary in the dtb and the wifi is working. These are claude's words:

"

T95ZPLUS (AW869A / AIC8800) with LYU’s image: fix for mmc1: error -110 whilst initialising SDIO card

Box: T95ZPLUS, H618, AW869A (SDIO 5449:0145, detected as AIC8801). Image: LYU4662’s Armbian build, 6.7.12-edge-sunxi64, with his aic8800 DKMS driver.

Symptom: aic modules load, but modprobe aic8800_fdrv gives “No such device”, /sys/bus/sdio/devices/ is empty, dmesg shows the CIS tuple being read and then mmc1: error -110 whilst initialising SDIO card / Failed to initialize a non-removable card.

I compared LYU’s DTB with the live Android DT. Pins, supplies and power sequence already match (SMHC1 on PG0–PG5, vmmc = DLDO1 3.3 V, vqmmc = ALDO1 1.8 V, 32 kHz clock out on PG10 via &rtc 1, reset PG18 active low). So it’s not a pinning problem.

What fixed it, in the mmc@4021000 node:

max-frequency: 50 MHz -> 25 MHz

removed: cap-sd-highspeed, cap-mmc-highspeed, mmc-ddr-3_3v, mmc-ddr-1_8v

wifi_pwrseq: added post-power-on-delay-ms = <200>

After that both SDIO functions enumerate, firmware loads, wlan0 shows up, nmcli connects, and it comes back after a reboot without the Ethernet cable.

I changed these together and didn’t test them individually, so I don’t know which one is essential. Only tested on this image/kernel and one box; Bluetooth untested. Newer revisions with other chips (e.g. YC8800D) are a different case.

If you use LYU’s image, replacing /boot/dtb/allwinner/T95zPlus-H618.dtb wt95zplus-aw869a-wifi-fix.zipith the patched one and rebooting should be all that’s needed. Happy to share the DTB/DTS if anyone wants it."

I tested it at my t95zplus, wifi is working. I attach the dtb and dts claude found out. Simply replace the DTB in /boot/dtb/allwiner/T95zPlus-H618.dtb by the dtb of the zip file:

Flash the image at an SD card

unzip the attached file in ~/Downloads

find your SD card sdX1 with lsblk (typically sdX1 is sda1 or sdb1)

then:

sudo mkdir -p /mnt/sd

sudo mount /dev/sdX1 /mnt/sd

ls /mnt/sd/boot/dtb/allwinner/ | grep T95

sudo cp /mnt/sd/boot/dtb/allwinner/T95zPlus-H618.dtb /mnt/sd/boot/dtb/allwinner/T95zPlus-H618.dtb.stock

sudo cp ~/Downloads/T95zPlus-H618.dtb /mnt/sd/boot/dtb/allwinner/T95zPlus-H618.dtb

sha256sum ~/Downloads//T95zPlus-H618.dtb /mnt/sd/boot/dtb/allwinner/T95zPlus-H618.dtb

sync

sudo umount /mnt/sd

Start your t95zplus and do the armbian installation.

Then you can initilize wifi on the box:

# 1. Hold kernel packages

sudo apt-mark hold linux-dtb-edge-sunxi64 linux-image-edge-sunxi64 linux-u-boot-t95zplus-h618-edge

apt-mark showhold

# 2. Optional: back up /boot

sudo cp -a /boot ~/boot-backup-$(date +%F)

# 3. Check WiFi state (rfkill needs sudo)

sudo rfkill list

sudo rfkill unblock wifi

# 4. Enable WiFi and scan

sudo nmcli radio wifi on

sudo nmcli device wifi rescan

sleep 5

nmcli device wifi list

# 5. Connect WiFi

sudo nmcli device wifi connect 'YOUR_WIFI_NAME' password 'YOUR_PASSWORD'

# 6. Verify

ip -br addr

ping -c3 -I wlan0 1.1.1.1

# 7. Test auto-connect (unplug the LAN cable first)

nmcli connection show

sudo reboot
