wl1271 configuration in ezsdk 5.04

Other Parts Discussed in Thread: WL1271, TXB0108, TXB0106

Hi.

We want to use wl1271 with dm8148. But i get the following message when trying to bring up wlan0.

root@dm814x-evm:~# ifconfig wlan0 up
ifconfig: SIOCSIFFLAGS: Cannot assign requested address


Is there any instruction how to bring up wl1271 while working with ezsdk 5.04 for dm8148?

Best regards,

Alexander Vasiljev.

    Alexander,

    Have you followed the wiki for calibration

    http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_Calibration_Proccess_NLCP

    Also can you confirm whether the TQS_S_2.6.ini file is valid and exists at the location specified and has the required permissions?

    Hi.

    I still cannot get it work. I tested the lines and they seem to be ok. I made test from mistral diagnostics and it passed well. But i notice that i use tiwi module Revision 4 with wl1271 PG3.1 and the linux kernel has ids only for PG10 and PG20. Can this be an issue?

    Alexander,

    I'm not getting much idea. But looks like you WLAN SDIO modules is not getting power back as SDIO read/write is failing. Can you just probe the power on pin of your module?

    We probed the power pin. It seems to be OK. We cannot be sure that other lines working well. Now we use txb0108 as voltage-level translator. We are going to probe txs translator and see if it will help.

    HI Alexander

      I also encountered the same problem with you.

    So I want to know whether you have solved  the problem?

    we use  txb0106  as voltage-level translator

    Hi Alexander

     My wl12xx module can work. The  reason that sdio write failed (-110) is sdio bus Impedance matching.
