DM814x / DM816x OpenLink WL127x support

HI,

We don't have any plans at this for enable WL127x on the DM816x processor.

There are plans for DM814x which are current gated by availability of functional WL1271 Adapter for that processor. Once we have a line of sight on functional hardware, we will announced Software plans on thw Wiki.

Openlink Drivers can run on any TI ARM based processor after porting, integration and validation with the Software Release for that processor and EVM.

Hi, Adnan, what does "functional WL1271 Adapter" refer to?  Is that HW or SW?  (thanks!)

There is a re-desing of the Catalog and VCAM Daughter cards for DM814x EVM  underway in order to accomodate a WL1271 Adapter.

So will the COM6L board we have work with the COM7 connector on the Centaurus platform?  (I was under the impression it would) :: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/p/131324/520826.aspx#520826

Hi Adnan

Do you have WL1271 driver that support DM8148 evm now?

When will be WL1271 Adapter (daughter board) available?

Hi Jammy

The Linux EZSDK Release 5.04.00.11 is available for download from http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html 
  
 This release supports DM816x and DM814x and has been validated on DM8168 PG2.0 and PG1.1 EVMs with DDR3 and DM8148 PG2.1 EVMs

that includes WLAN and Wireless Connectivity drivers (on DM814x)

This release includes the features and components listed in the following Wiki page http://processors.wiki.ti.com/index.php/EZSDK_Feature_List

Hi Eyal

I have downloaded the EZSDK (5.04.00.11) for dm814x-evm and am testing the WLAN interface. I am able to connect to the Access point modes (b, g) in different security encryptions (wep, wpa, wpa2) successfully, but i am unable to connect to access point in 'n' mode with security encryptions (wep, wpa, wpa2). However I am able to connect to n mode Access point in open authentication.  Please give your suggestions on this issue. I have attached the log of the wpa_supplicant in debug mode while trying to connect to access point ( in 'n' mode and WPA encryption).

Hi Eyal

I also want to install WL1271 on my DM8148 evm. But my first question is how to connect WL1271 module to Expansion I/O board on the evm. I cannot find any data sheet about the expansion I/O board. My second  question is how to build the WLAN driver.

Thanks,

Jammy

Hi Eyal, in continuation of my previous post on testing of WLAN with n-mode access point in security modes (wep, wpa, wpa2) I have done the same test (AP in n mode with security wpa - tkip) with a different model access point (cisco aironet 1200). The station is getting past the Association phase to 4WAYHANDSHAKE, it it Fails after this. As i see in the sniffer it says "IEEE 802.1X authentication Failed" as the reason for de-authentication. I am not using any Enterprise security here.  I have attached the log of the wpa_supplicant in debug mode while trying to connect to access point ( in 'n' mode and WPA encryption).  Also the access point model used for testing in my previous post  is WRT120N, with this access point the reason for association failure given by the access point is "Wireless association denied: 10 Cannot support all the requested capabilities" . Please give me your suggestions on both of these issues.

Hi Jammy,

Please see the DM814x picture for board installation in 3757.DM814.zip

In addition please see build instructions guide in our WiKi page in http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_mac80211_WLAN_build_scripts
