OMAP-L138 + WL1271 is it possible?

Hi,

I am new to OMAP developement and our company has just recently chosen OMAP-L138 as our base platform for future product development.

One of the first products we are going to use OMAP-L138 will require wireless connectivity which we found out that the WL1271 can provide (Wifi + bluetooth).

However, base on the post I've read from the forum I only found support for the WL1271 on the OMAP35xx.

Can you please clarify if the OMAP-L138 can be interfaced with the WL1271?

Also are their available any Linux device drivers for the WL1271 which can be installed in the Linux package for the OMAP-L138.

 

Please advice.

    This is physically possible, that is the OMAP-L138 has the sufficient interfaces (primarily SDIO) to manage the connection. However there is not currently any hardware design in place to interface the OMAP-L138 to the WL1271 that I am aware of (or any immediate plans for one).

    Also are their available any Linux device drivers for the WL1271 which can be installed in the Linux package for the OMAP-L138.

    The drivers for the WL1271 on the OMAP3 are open source, so there is a possibility of porting them into the OMAP-L137 kernel, however this is likely going to be a significant task as it will most likely take more than just rebuilding the drivers for the OMAP-L138 kernel, if it is even possible with the given documentation. If you wanted to pursue this further today, you would probably want to work with a third party as suggested here on the wiki.

    The WL1271 is going to be an optimal solution, particularly if you need BT and WiFi in a low power, compact application, though if the cost of the porting effort to OMAP-L138 is determined to be too high you may consider an off the shelf USB solution, as this is what we would have traditionally recommended before the availability of the WL1271 module.

    Hello,

    I would like to mention that TI is working on defining a way to deploy a similar platform for connecting the WL1271 to the OMAP-L1. We don't have a schedule yet because we're in the definition stage, but our goal would be for 2nd half of this year.

    In the mean time, as Bernie commented, a third party can offer a solution and given the advantages of WL1271 over off the shelf USB solutions (e.g. support for both WLAN and Bluetooth; support for 802.11n; low power), it is worth considering.

    Hi,

     

    Has there been any update on the development of the WL1271 + OMAP-L1?

    We would appreciate any code dump even if it is still under development

    Hello,

    Unfortunately, we've had some delays and don't have an update on the WL1271+OMAP-L1 development yet.  We'll provide an update later in 3Q this year.

    Hi all,

    I'm trying to test my wl1271 wlan module on SDIO. For that I'm using latest wl1271 driver from wireless-2.6 tree (using compat-wireless). At the moment I'm looking for NVS file for my device: the driver needs two files, on is the firmware called wl1271-fw.bin, the other one is the nvs file called wl1271-nvs.bin.

    I wrote directly to driver's developer and he suggested me to ask for a procedure to extract nvs file from my device, does anyone know how it could be done?

    Thank you for your help,

    pz

    The following link describes how to create NVS file  using wlan_cu (CLI application)

    Are there any new updates for the status of TiWi support ?

    Just trying to keep this question active.

    Hi,

    we will have AM1808 release which is based on TI proprietary Driver (M6 release) at end of Q1 2011.

    in addition we will have a release for AM1808 and for OMAPl138 which is based on the mac802.11 at Q2 2011
