Hi,
I am looking for porting EM7595 drivers into Linux 2.6 Kernel. Can you please let me know what changes are required.
does this help?
Hi,
My linux kernel is 2.6. So looking forward to backport the qmi and qcserial drivers in 2.6 kernel. Any inputs on it?
can you see the USB enumeration after adding VID/PID in your qcserial driver?
We were able to add vid/pid in qcserial. Below are the logs. We backported some patches in to 2.6 kernel to make the driver works. we are not sure all the necessary changes are there to make a connection. How do we make a connection now? Can we use the sample application under MBPL (lite-qmi-connection-manager) ? which binary works with mips64 arm architecture?

First of all, the MBPL officially only supports linux kernel equal to or larger than 4.4.
So I would suggest you to use some tool directly coming from linux.
If you are using RMNET port in AT!USBCOMP, you can first try qmi-network tool to see if it can establish data connection:

64 bytes from 8.8.8.8: icmp_seq=3 ttl=117 time=29.6 ms
On the other hand,. EM7595 has MBIM interface which is from Linux generic MBIM driver.
You can try the following:
- sudo apt-get install libmbim-utils
- Make sure MBIM interface has been enabled in AT!USBCOMP
AT!ENTERCND=“A710”
AT!USBCOMP=1,1,100D
AT!RESET
- Modify /etc/mbim-network.conf to include APN/username/password of SIM card, e.g.
owner@CNHKG-EX-001367:~$ cat /etc/mbim-network.conf
APN=CMHK
APN_USER=
APN_PASS=
APN_AUTH=
PROXY=yes
- sudo mbim-network /dev/cdc-wdm0 start
- sudo dhclient wwan0
- “ifconfig wwan0” should show IP address
- ping 8.8.8.8 -I wwan0
Thank you so much. Where is this files and binary available?

You need to first install
libqmi-utils and libmbim-utils
Here is the o/p from qmi-network . Not sure it is success. Could not see any interface.

Can you ping 8.8.8.8 via the wwan0 interface?
Did you try MBIM mode by the following?
- sudo apt-get install libmbim-utils
- Make sure MBIM interface has been enabled in AT!USBCOMP
AT!ENTERCND=“A710”
AT!USBCOMP=1,1,100D
AT!RESET
- Modify /etc/mbim-network.conf to include APN/username/password of SIM card, e.g.
owner@CNHKG-EX-001367:~$ cat /etc/mbim-network.conf
APN=CMHK
APN_USER=
APN_PASS=
APN_AUTH=
PROXY=yes
- sudo mbim-network /dev/cdc-wdm0 start
- sudo dhclient wwan0
- “ifconfig wwan0” should show IP address
- ping 8.8.8.8 -I wwan0
No, I am running only with qmi mode. I dont have the mbim driver port to 2.6 kernel yet to try mbim.
Below is the error log when running in qmi mode.
Device link layer protocol retrieved: raw-ip
Getting expected data format with ‘/opt/libqmi-stack/bin/qmicli -d /dev/cdc-wdm0 --device-open-qmi --get-expected-data-format’…
cdc-wdm wdm_open() submit validity rv=0
error: cannot get expected data format: Expected data format not retrieved properly: Failed to open file ‘/sys/class/net/usb0/qmi/raw_ip’: No such file or directory
The usb0 interface is created but no ip address is getting and the interface is down.
Regards
simon
can you create the raw_ip there by yourself?
I am not sure ppp dial up is supported, but you can have a try and see if there is any luck
I dont see the file /sys/class/net/usb0/qmi/raw_ip created. Probably needs a kernel patch to support raw ip?
Regards
Simon
See if this helps
FYI, I just tried on ubuntu 11.04 with kernel 2.6.38, I can do ppp dial up with EM7595 on AT command port with firmware 03.01.00.10:
