[Resolved] Questions about LSR TIWI-R2 Module
Hi,I have some questions about LSR TIWI-R2 Wireless Modules. Would it be possible to have some support ?What about compliance with the IEEE 802.11n standard? Which features does it support ?Which Linux kernel is supported with the Wi-Fi chipset? Does the driver work with the Linux kernel release 2.6.34 ?Questions about the Linux driver of the Wi-Fi chipset:• Does the driver support all the features available with the Wi-Fi chipset? If no, which features are supported ?• Is there a list of known issues and a plan to solve them ? The documentation says that the Wi-Fi chipset is ultra low-power but what could we expect about it in suspend / standby state ?Best regards,
LSR TIWI-R2 is similar in wlan function to the previous board, but there are fixing in layout mainly for better production and not due to wlan issues.
The board is based on WL1271 chip that support 802.11 bgn bands. And the feature list is depends on the SW that we provide. The SW that we provide were developed for OMAP3530, AM37x and AM18x platforms and is based on WiLink6 M6 Software release that is published in our WiKi in http://processors.wiki.ti.com/index.php/ARM_Processor_Wireless_Connectivity_Downloads
Also for wlan features please see in the Release notes in the same page.
The kernel release in 2.6.32 for OMAP3530, AM37x and 2.6.33 rc4 for AM18x
we plan to have mac802.11 open source release that will be based on 2.6.37
The WiFi driver was design to pass WiFi certification, and relevant information please find in the release notes.
as for suspend resume we do support however i dont have the current consumption numbers yet for LSR TIWI-R2, however it will be the figures that are in the data sheet as provided in LSR website
Thanks Eyal for this answer,
Regarding power consumption in suspend, I had a look at the datasheet but did not found anything except a "Dynamic Mode" ...
I think that in LSR site there is an email for customer questions, would you like to try it? I will also try to get the information from LSR.
There are several suspend mode of operation, the one that consume lowest current is shut down mode were the 1271 module is disconnect from the WLAN network. In that case the module (1271 and RF module) consume about 3.5 mAmp (I don’t have the exact figure)
Thank you very much Eyal for the help : )
