Hello,
I'm working on a developing an new device at the Draegerwerk AG & Co.KGaA.
I'm also evaluating the possibilities of the Aquaris E4.5 and Ubuntu Phone OS
for the new device.
Therefore I'm trying to connect a USB-to-Ethernet-Adapter to the Aquaris E4.5.
The Goal is to communicate from the Phone to Draeger devices using the Ethernet
network.
To achieve that I downloaded the kernel sources from
https://github.com/bq/aquaris-E4.5.git.
Afterwards I manipulated the 'project' file at
/aquaris-E4.5/mediatek/config/krillin/autoconfig/kconfig:
Here is what I Changed:
# USB Network Adapter
CONFIG_USB_USBNET_MII=y
CONFIG_USB_USBNET=m
CONFIG_USB_NET_AX8817X=m
CONFIG_USB_NET_AX88179_178A=m
CONFIG_USB_NET_CDCETHER=n
CONFIG_USB_NET_CDC_EEM=n
CONFIG_USB_NET_CDC_NCM=n
CONFIG_USB_NET_HUAWEI_CDC_NCM=n
CONFIG_USB_NET_CDC_MBIM=n
CONFIG_USB_NET_DM9601=n
CONFIG_USB_NET_SR9700=n
CONFIG_USB_NET_SR9800=n
CONFIG_USB_NET_SMSC75XX=n
CONFIG_USB_NET_SMSC95XX=n
CONFIG_USB_NET_GL620A=n
CONFIG_USB_NET_NET1080=n
CONFIG_USB_NET_PLUSB=n
CONFIG_USB_NET_MCS7830=n
CONFIG_USB_NET_RNDIS_HOST=n
CONFIG_USB_NET_CDC_SUBSET=n
CONFIG_USB_ALI_M5632=n
CONFIG_USB_AN2720=n
CONFIG_USB_BELKIN=n
CONFIG_USB_ARMLINUX=n
CONFIG_USB_EPSON2888=n
CONFIG_USB_KC2190=n
CONFIG_USB_NET_ZAURUS=n
CONFIG_USB_NET_CX82310_ETH=n
CONFIG_USB_NET_KALMIA=n
CONFIG_USB_NET_QMI_WWAN=n
CONFIG_USB_NET_INT51X1=n
CONFIG_USB_SIERRA_NET=n
CONFIG_MTK_ION_DEBUG=n
CONFIG_USB_MTK_DEBUG_FS=n
CONFIG_USB_MTK_DEBUG=n
I was able to build the kernel using the sudo ./makeMtk -t krillin n k command
and the boot.img using the ./mkbootimg.sh script in the 'testboot' directory.
After flashing the boot.img on the Aquaris and moving the new drivers mii.ko,
usbnet.ko und asix.ko to the Phone I was able to load these three drivers with
'insmod'. Now I added the following lines at the /etc/network/interface:
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0
After I plugged in the USB-to-Ethernet-Adapter and started the eth0 with 'sudo
ifup eth0' I was able to see the interface with 'ifconfig:
eth0 Link encap:Ethernet HWaddr 00:80:C8:F8:4A:51
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0 B) TX bytes:0 (0 B)
Now I it was possible to communicate over Ethernet to different devices. But
another problem occurred. The phone shuts down communication to the
Internet through the SIM card and it isn't possible to make any calls. The
command 'nmcli' gives the following output:
DEVICE TYPE STATE CONNECTION
ril_0 gsm disconnected --
ril_1 gsm unavaible --
etc...
'dmesg' gives:
[ccci/net] (1)CCMNI0 close
The phone starts to react quite slow on all commands, like changing the app.
With the top command I could see that there were like 200 MB free cache space.
Is there any way to fix this Problem or to maybe an easier way to connect an
USB-to-Ethernet-Adapter to the Phone?
