wireless support for ralink

Other Parts Discussed in Thread: AM1808

I have an AM1808 running on a Logicpd eval board. I'm trying to add support for rt2x00 Wlan with a usb adapter.

I found what i though would be a good reference to help me (http://processors.wiki.ti.com/index.php/Davinci_USB_WLan) but it turns out to be part of a MontaVista tool set and not useful to me because of that.

I realized that since it's part of the Linux kernel I should be able to enable it and rebuild the kernel. Unfortunately the Davinci default configuration doesn't provide that capability. I don't have much experience re-jigging defconfig files to add support for new functionality.

So what's my best approach to achieve my goal? Learn how to compile and install kernel modules with the source code from linux->drivers->net->wireless->rt2x00. Not that I'm afraid to learn. Just on a bit of a time crunch.

thanx

/carl

    Another option would be to ask the vendor of the WLAN device how to add the Linux driver. They should know their code and how to integrate.

    Carl,

    I believe you need the tarball of linux drivers provided by ralink and cross compile for your platform.

    I have compiled ralink drivers for my home pc some time ago. They do have built-in support for one of the DaVinci processors in their make file. You can probably follow this example to build AM1808.

    Again, I wouldn't be able to help on USB related issues.

    Have you already seen this wiki: http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page

    Sanjeev,

    Where would you have gotten this tarball? I downloaded '2010_0817_RT73_Linux_STA_v1.1.0.4.tar.bz2' from Ralink but there's no mention od Davinci in any of the makefiles.

    The only thing I see at serialmonkeys is a way to clone their repository using git which provides a driver under a linux kernel at drivers->net->wireless->rt2x00, which is already a part of the Linux kernel I'm working with anyways.

    Regards,

    /carl h.

    I found the magic config setting that exposes Ralink support in the kernel. Enable CONFIG_MAC80211 under 'Networking Support -> Wireless'. Once enabled go into 'Device Drivers -> Network Device Support -> Wireless LAN' and select Ralink.
