DM814x / DM816x OpenLink WL127x support
Hi, TI Team,
With the announcement of the DM814x and DM816x platforms recently, I haven't seen updates in this http://processors.wiki.ti.com/index.php/ARM_Processor_Open_Source_Wireless_Connectivity to reflect support of WL127x products with these two product families.
Can you confirm that OpenLink mac80211 drivers and such will run on these DSPS platforms? They're not referenced at openlink.org, and the DM81x products are absent as I said from the processors wiki re: wireless connectivity.
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
Do you have WL1271 driver that support DM8148 evm now?
When will be WL1271 Adapter (daughter board) available?
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
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).
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.
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.
I will review the logs and send response
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
Is this module you plugged in DM814x EVM board?
I think it is, the link i have is http://www.murata-ws.com/view.php?http://www.murata-ws.com/datastore/media/dc_com6m_brief.pdf
