Not able to compile new driver

[umashankar]

Hi,

Using the latest 14-Jun OS version. The issue is that am unable to get the wifi working. The dongle am using is a Tenda w311m, which apparently uses a ra5370 chip. Following the advice given elsewhere in the forums, am trying to compile the driver off the sources downloaded from the mediatek website. It is failing in the beginning itself saying it's unable to locate the build file in the lib/modules folder. The OS (uname -r) is 3.12.0-g0bc9c3a-dirty, and it's not able to locate this folder in the lib/modules. Cannot build the folder also, as apt is not able to locate the package 3.12.0-g0bc9c3a-dirty. Please explain how to proceed.

linaro-nano:~> uname -r
3.12.0-g0bc9c3a-dirty

Other info:

Any other alternative (without compiling etc) to get the wifi working is also fine.

Hi, the 14-03-06 system image is from 2014-03-06, that is, 6th of March. The important thing is the uname output you posted anyway.
Edit: I meant the 14.03.06 SD card image file from ; there is a rootfs image (not the whole card that has both the /boot and /root partitions) at that has the timestamp 140603 which is 3rd of June.

You can build an updated disk image as documented here: https://github.com/parallella/parallella-ubuntu
That would be based on Ubuntu 14.04 which apparently includes the RT5572 driver: https://bugs.launchpad.net/ubuntu/+sour ... ug/1020650
You mention the RA5372 but since you are compiling the RT5572 driver I suppose it's the same.

If you still need to compile the module there, you'll probably need to install the kernel-headers-generic package. This won't work in the 14-03-06 because the kernel version (3.12) does not match the packages (3.11).

I have compiled USB wireless drivers in other systems like the GK802 but I don't use one in the Parallella so I can't give you more than the general advice above.

Thank you, Alberto and Andrew. Can you please suggest how I make the usb wifi work?

[AlbertoGP]

Oh, I see. Well, then I would create that modules directory by hand, then see what's missing next and get those things from the git repository.

You can get a copy of the Parallella kernel files with git: `git clone https://github.com/parallella/parallella-linux-adi.git`
Another way is to use the "Download ZIP" button in the GitHub page that Andrew mentioned. It's on the right-hand side and would be faster because it does not contain all the changes, just the current version.
The file is called "xcomm_zynq.zip" because that's the branch name in the repository.

[umashankar]

Thank you Alberto. Will try it and let you know how it goes.
