Help complining Firmware support KPN superwifi

Hi everyone,

I’ve successfully installed OpenWrt on a KPN Super WiFi Point (Arcadyan hardware exactly type not know) using the firmware from the KPN Experia (Arcadyan WE420223-99), as outlined here: OpenWrt Arcadyan WE420223-99. The device boots into OpenWrt, and many functions work, but I’m facing some issues and need help generating a custom firmware.

Current Status:

  • The device boots successfully into OpenWrt.
  • One of the WiFi chips (Mediatek MT7615N) works, but only on the 5 GHz band. The 2.4 GHz band is not functioning.

Hardware Details:

  • Flash Chip: Winbond Q250JVFJQ 2045
  • WiFi Chips: 2x Mediatek ARM MT7615N 2105BFSL ACMSAK1P
  • RAM: 1GB DDR3 (Winbond W631GG6KB12J 60218L100ZZ2 110PUA TWN)
  • CPU: Mediatek MT7621AT

Each wifi chip is in its own band.
Do

iw list | tee -a /tmp/wifi_info.txt

Then transfer it to your PC and use like notrepad++ to locate channel maps.

(Thats Belgium, Should be same down north)

no i dont think that is it my board have 2 mt7615n chips
almost the same as shown in this topic: Need help adding support for the bt wifi disc - For Developers - OpenWrt Forum except i have 1gb of Ram

and this device [OpenWrt Wiki] D-Link DIR-878 A1 except i have 1gb ram and only 1 gbs ethernet port

4

Please check in place. Picture with 2 kind of 5GHz radios seems wrong.

5

i have also 2 wlan chips on the pcb i think 1 is for the mesh and the other for the wifi?

6

Does it detect good powers ie if it got correct calibration data from system partitions?

7

Looks like the firmware you have used isn't actually compatible. post the bootlog - I expect we will see firmware load failures due to incorrect DTS.

You can get the bootlog from luci or via dmesg command in an ssh session

There's the 'smoking gun' - the mtk kernel modules aren't able to load config data while booting. You will need to review the correct partition layout from the factory firmware, edit the openwrt dts to match and recompile.

There also looks to be only 2 mt7615e's devices being brought up, where you would expect to have 3, 1x 2.4ghz and the 2x 5ghz interfaces. Your dts will need to correctly specify all of them for the kernel to attempt to enabled them.

Thank you for your quick reply,

Is it posible tonread out the original dts layout trough spci and a raspberry connected directly to the flashchip?

11

if dtc is installed you can unpacked like

dtc -I fs -O dts /sys/firmware/devicetree/base

if no dtc , try to install it

opkg install dtc

or backup contents of /sys/firmware/devicetree/base, and transfer it to a linux machine and run dtc from a terminal there.

thank you,

when i do this i get a lot of information also of my raspberry pi
but i think we need this:

you cannot use it directly, you'll have to pick out the useful information and translate it into your dts as needed. Fill in the blanks for lack of better words

14

thanks i dont understand how to do that
can i adjust an existing firmware file like the one of de arcadyan? en where do i start?

i have check the dts of accespoint and the one from de arcadyan and they are the same sizes?

15

best place to start would be the some docs
https://openwrt.org/docs/guide-developer/hw.hacking.first.steps
https://openwrt.org/docs/guide-developer/add.new.device

they're outdated, but enough to give you the generally idea of the work flow.

next find a supported device most similar to yours and go thru the sources, use or edit the dts to work for your device with the information gained in from your unpacked dts.

i have got wifi working!
i have found a workaround on the web:

opkg update

opkg install kmod-mt76-connac

opkg install kmod-mt7615-common

opkg install kmod-mt7615-firmware

opkg install kmod-mt7615e

wifi reload

i can create and connect to a 2,4 and 5 ghz band.

unfortunatly after an reboot my wireless config is back to stock.

17

that's strange, perhaps a uci commit before wifi reload...

you could also use a uci defaults script to set these values on boot, a quick and dirty solution, which may be sufficient for testing it for the time being ? it comes down to the time you are willing to invest and your intentions ie adding official support for the device, or personal use etc.

as an example you could add the following file and contents below

/etc/uci-defaults/99_set_wifi

#!/bin/sh


uci set wireless.radio0.disabled=0

uci set wireless.radio1.disabled=0

service network restart

cat << EOF > /etc/config/wireless

config wifi-device 'radio0'

option type 'mac80211'

option htmode 'HT20'

config wifi-iface 'default_radio0'

option device 'radio0'

option network 'lan'

option mode 'ap'

option ssid 'openwrt'

option encryption 'psk2'

option key 'password'


config wifi-device 'radio1'

option type 'mac80211'

option channel '36'

option hwmode '11a'

option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0'

## return 1 so script runs on each boot

return 1

from a terminal, make the script executable and reboot

chmod +x /etc/uci-defaults/99_set_wifi
reboot

this is not a solution, any changes to your wireless settings would need to be reflected in the script. But it may allow you to test before deciding to put in the effort to add the device officially.

How did you flash the Experia Wifi image on the Superwifi? With the webinterface or by writing directly to the flash chip?

19

i have writen it directly to the flashchip

20

I'll see if I can get my hands on a Superwifi 1 for cheap, would be nice to give these devices a second life with OpenWrt. Also a Superwifi 2, if only for device discovery.
