    ##edit: kernel v4.1-rc5-unstable craches too. rc3 seems the most "reliable".

    Re: Asus X205TA hardware support in Ubuntu

    Hey guys. I am betting our devices are very similar.

    http://ubuntuforums.org/showthread.p...1#post13293789

    I have the brcmfmac wifi working very well on my switch. I can't get the SDcard reader to mount rw though. I am using the custom 4.0 release kernel that was posted in the Asus T100 G+ community.

    Sound is an interesting beast... It just flat doesn't work but I can get the machine to see the chipset after boot.

    Code:
    root@switch:~# cat /proc/asound/cards
    --- no soundcards ---
    root@switch:~# sudo alsa force-reload
    Unloading ALSA sound driver modules: snd-soc-sst-byt-rt5640-mach snd-intel-sst-acpi snd-intel-sst-core snd-soc-sst-mfld-platform snd-soc-rt5640 snd-soc-rl6231 snd-seq-midi snd-seq-midi-event snd-soc-core snd-rawmidi snd-compress snd-pcm-dmaengine snd-seq snd-pcm snd-seq-device snd-timer snd-soc-sst-acpi.

    Thanks,

    Hi, the url http://www.filedropper.com/x205ta seems to be gone for me (it redirects to http://www.filedropper.com). Could you re-upload it? I can't find a copy of brcmfmac43340-sdio.txt and I don't have a nvram-* file in my efivars folder

    Re: Asus X205TA hardware support in Ubuntu

    Also it seems the trackpad isn't supported as a trackpad -- it only gives me basic mouse configuration.

    In /proc/bus/input/devices I see:

    I: Bus=0018 Vendor=04f3 Product=0401 Version=0100
    N: Name="ELAN0100:00 04F3:0401"
    P: Phys=
    S: Sysfs=/devices/platform/80860F41:03/i2c-11/i2c-ELAN0100:00/0018:04F3:0401.0002/input/input9
    U: Uniq=
    H: Handlers=mouse0 event9
    B: PROP=0
    B: EV=17
    B: KEY=30000 0 0 0 0
    B: REL=103
    B: MSC=10
    ...which led me to this bugzilla: https://bugs.launchpad.net/ubuntu/+s...x/+bug/1439111

    The bugzilla isn't for Bus=0018 Vendor=04f3 Product=0401 Version=0100, it's for Bus=0018 Vendor=04f3 Product=0400 Version=0100, but maybe it's close enough to work for the x205ta touchpad? I'm not sure how to test the fix there but maybe someone here can test it.

    Hi everyone, same thing for me, could you please reupload the files ? Or at least post the content of brcmfmac43340-sdio.txt ? I have some files in my /sys/firmware/efi/efivars/ directory, but no nvram-* one... Thanks !

    Re: Asus X205TA hardware support in Ubuntu

    can someone with working wifi kindly post your brcmfmac43340_sdio.txt?

    I tried to browse the /sys/firmware/efi/efivars but there's no `nvram-74b00bd9-805a-4d61-b51f-43268123d113`.
    I only had `BDADDR-74b00bd9-805a-4d61-b51f-43268123d113`, but it's a binary file with something I dunno what that is inside (i guess it has something to do with the bluetooth mac address, maybe?).
    Code:
    # ls -l *74b00bd9*
    -rw-r--r-- 1 root root 10 Jun  8 06:20 BDADDR-74b00bd9-805a-4d61-b51f-43268123d113
    Code:
    # xxd BDADDR-74b00bd9-805a-4d61-b51f-43268123d113 
    0000000: 0700 0000 04e6 7642 94a3                 ......vB..
    I couldn't find any text-looking brcmfmac43340_sdio.txt as the one provided in https://github.com/jfwells/linux-asu.../firmware/brcm.
    I tried to use modified-nvram3.txt but it didn't work.

    I'm getting
    Code:
    [ 1632.860100] brcmfmac_sdio: probe of mmc1:0001:1 failed with error -22
    [ 1632.904020] brcmf_sdio_drivestrengthinit: No SDIO Drive strength init done for chip 43340 rev 2 pmurev 20
    [ 1632.904562] usbcore: registered new interface driver brcmfmac
    while trying to modprobe brcmfmac.

    I'm using the latest daily-build kernel:
    Code:
    # uname -a
    Linux Palabuntu 4.1.0-999-generic #201506062205 SMP Sun Jun 7 02:06:17 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
    ps. I'm using bios version 208, does that make a difference?

    Re: Asus X205TA hardware support in Ubuntu

    for those people suffered the wifi nvram.txt problem, I've found a solution.

    dunno why, I'm having a 10byte binary /sys/firmware/efi/efivars/BDADDR-74b00bd9-blah, cp it to /lib/firmware/brcm/brcmfmac43340-sdio.txt just won't work.

    So, I poked around the internet and found this:
    https://github.com/lubing521/bcm-wic..._nvram_image.h

    and composed the char array into a txt file, placed under /lib/firmware/brcm.

    and viola! it worked!

    now i'm having inbuilt wifi working.

    the NVRAM_GENERATED_MAC_ADDRESS is not a problem, no matter what I write it just reverts to the hardware default.

    use "macaddr=00:11:22:33:44:55\n" for that line should suffice.

    Hello Everybody..So finally in this moment the only think doesn't work is the sound? The Wifi is working good now with the last modifications? I want to ask also there is hardware acceleration in Graphics card with browsers?

    Hello,

    Not really :

    - The sound card does't work now, but Michele Curti assisted by Liam Girdwood from Intel has work in progress and I hope soon we'll have an alsa module for the rt5648. cf . http://comments.gmane.org/gmane.linux.alsa.devel/138822

    - We always have a hang of the laptop which need a hard reboot. Nobody knows why and how for the moment.

    - The touchpad is working, but lacks multitouch. I didn't manage to make it works, even with max109 's workaround. I did recompile kernel 4.1 rc6 with the patch that works on a Lenovo Yoga 3 (cf. https://lkml.org/lkml/2015/3/31/929) with adding of the 0x0401 in hid-core.c , but when reboot, the touchpad doesn't respond anymore.

    - And finally the suspend functionnality is broken (not really important in my opinion because the battery power life is great : 14H with screen luminosity decreased and only internet brownsing/terminal work after i did some optimisations and powertop tunnings)

    Everything else is working great.

    So the laptop is really great (battery life, cpu enough for my needs, lightweight) and even if it is usable under linux (i run archlinux, not ubuntu), support is'nt complete.

    Sorry for my english mistakes, i'm not fluent, i'm french native language.
    Have a good day.
