WL1831 disconnect network and FW is recovered frequently

Other Parts Discussed in Thread: WL1831, WL1271

Hi TI,

We got a question about WL1831. They alway disconnected the AP, and in kernel we found the firmware is recovered frequently.

Could you give us some suggestions? Is it related to power-saving mode? How to don't let WL1831 enter into power-saving mode? Is core.conn.sta_sleep_auth (in wl18xx-conf.bin) related to power-saving mode? And how to set it?

Please see the log below for detail:

    Hi Li,

    The release version that you are using is very old (more then 1.5 years old)
    Please see our latest SW release in the following link

    From the SW Release that you are using to the latest one we had many stability and robustness fixes, and we do recommend to upgrade to that latest release first.

    Hi Shahar,

    The latest driver is based on Kernel version 3.14.0, but our kernel version is 3.4.0. It is a big gap. It is not easy to move to the latest driver, as there are so many differences in kernel files. If we move it, could you give us some suggestion?
    We also found this problem on WL1271. Is it related to our configs or network settings? Please see below:

    Hi Li,

    for the WL127x issue, please open a new note and we will try to provide the information there.

    for the Kernel issue,
    all of our releases support Backports and Compat option
    the build script will allow you to build the SW release with almost any Kernel you want (just add the correct Kernel into the script path)
    Please also not that R8.4 (previous release) was released with Kernel 3.2 and 3.12, so if needed you can port to R8.4 Release (in the NLCP releases there is a link to previous release) and to upgrade the FW to R8.4 SP

    Hi Shahar,

    Thank you very much for your quick reply.
    The Backports seems good. Could you give me a guide/example for using it?

    TI__Expert 5840 points
    Li,

    You should use the build script for that:
    processors.wiki.ti.com/.../WL18xx_System_Build_Scripts
    please note that in the section of "Step 2: create setup-env file" you need to provide the Kernel you use

    Hi Shahar,

    It seems very helpful. I'll have a try. Thank you very much!

    HI Shahar,

    I followed the steps to build, but there are two questions:

    1. When I use './build_wl18xx.sh modules', it only outputs compat.ko and cfg80211.ko. There is no WL18xx.ko and so on. Why?

    2. When I use './sudo_build_wl18xx.sh update R8.5', I got below error. Could you kindly tell me why? Is it related to my ubuntu environment?

    Hi,

    With regards to (1), can you check if "CONFIG_CRYPTO_CCM" is enabled in your kernel config file? If not, can you enable it and see if the modules are getting built?

    Regards,
    Gigi Joseph.

    HI Shahar,

    I enabled "CONFIG_CRYPTO_CCM", but the result is same. I also got the same error prints. My kernel version is 3.4.48 and used in OMAP4. The kernel is in the release of 4AJ.2.5P2 OMAP4 Jelly Bean Release.
    Do you have any suggestions for this?

    Hi,

    I built out the new driver kernel, and use the wl18xx-conf-defalut.bin. And it seems the drivers can't run. Wifi module can't be enabled.

    The kernel log is below:

    Hi,

    After you insmod wlcore_sdio, the wlan0 interface should be created.
    Do you see that when you do "ifconfig -a" ?

    In Android, I see the log:

    Is it the drivers loaded failed? But all wifi drivers are inmod ad below:

    Hi,

    The log:
    <6>[ 283.776458] ADDRCONF(NETDEV_UP): wlan0: link is not ready

    is normal - I see it during boot up at my end too.
    From the logs that you have pasted, it looks to me that the wl18xx is up.

    Can you share me the results of "ifconfig -a" ?

    Regards,
    Gigi Joseph.

    Hi Joseph,

    In Android, I saw the log:
    E/WifiStateMachine( 358): Failed to load driver!
    E/WifiStateMachine( 358): DriverFailedState
    It seems Android insmod failed, right?

    But all wifi modules drivers are insmoded as below:

    Joseph,

    In my code, there is no 'iw'. There have wlconf and cabilitor.

    Hi,

    Please see:

    wlan0 Link encap:Ethernet HWaddr 70:72:CF:09:00:63
    UP BROADCAST MULTICAST MTU:1500 Metric:1
    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

    wlan0 is "UP"

    Do you get results if you do: "iw wlan0 scan | grep SSID" ?


    Regarding the error thrown by Android - "Failed to load driver!" - I think you need to check the integration (either the init.rc or the libhardware_legacy changes).

    Regards,
    Gigi Joseph.
