Incorrect wl18xx-conf.bin file size with mainline kernel 4.1

Other Parts Discussed in Thread: WL1835, WL1835MOD

Hello,

Host platform: Altera Cyclone V with ARM A9.

OS: Poky Linux with kernel 4.1 (built-in wl18xx drivers).

Module: TI WL1835 / 1837

Firmware: FRev 8.9.0.0.48, Rev 8.2.0.0.232

I'm using the 4.1 mainline kernel with built-in driver for wl18xx. Firmware is built from git://git.ti.com/wilink8-wlan/wl18xx_fw.git, branch 'ap_dfs'. After generating the wl18xx-conf.bin, I get the following error:

[    9.571368] wl18xx_driver wl18xx.0.auto: Direct firmware load for ti-connectivity/wl1271-nvs.bin failed with error -2
[    9.575138] wlcore: ERROR configuration binary file size is wrong, expected 1226 got 1229


After reading the other posts regarding this subject, I assume I am not using matching firmware/drivers, but I am unable to determine the correct version, nor do I know how to build a different driver version into the kernel.

Please advise how to select the correct driver version.

Best,

Tobias

    Hi Tobias,

    Please use the wlconf utility from git://git.ti.com/wilink8-wlan/18xx-ti-utils.git (git tag: "R8.6").

    Regards,
    Gigi Joseph.

    Hi Gigi Joseph,

    When I do 'git checkout -b myR8.6 R8.6', wl18xx-conf-default.bin still has 1229 bytes. I reran the configure-device.sh script, but the generated wl18xx-conf.bin file also has 1229 bytes.

    Can you point me to the correct release/tag of the wlconf script and the wl18xx-conf-default.bin file?

    Best,
    Tobias

    Hi Tobias,

    Apologies! Can you please try the R8.5 git tag?

    When I try tag R8.5, I get the following messages:

    The file size of the wl18xx-conf-default.bin is 1226 as it is expected from the firmware. I don't understand the rest of the error messages.

    # EDIT #

    When I copy wl18xx-conf-default.bin to /lib/firmware/ti-connectivity/wl18xx-conf.bin, the firmware is loaded. The configure-device.sh script still complains that it can't get the file size, but it does not give the error messages any more.

    Best, Tobias

    Hi Tobias,

    Can you try building the wlconf with your setup-env and see if the problem is gone?

    Hi Gigi,

    I'm using bitbake (recipe from `meta-arago-extras` layer) to build wlconf, I haven't used setup-env. When I do, I get an error message

    .../build-utilites/fs/lib/libnl-3.a(utils.o): In function `nl_prob2int':

.../build-utilites/src/libnl/lib/utils.c:378: undefined reference to `lrint'

    After copying wl18xx-conf-default.bin to /lib/firmware/ti-connectivity/wl18xx-conf.bin, I was able to run wlconf without errors. I think the problem is gone.

    Thanks for your help!
