Linuxium iso don’t even boot on my jumper
August 27, 2016 at 12:57 am #48099Which specific Broadcom Wifi NIC device is it? If you can boot from a Live-USB…
What is the output of running this in a Terminal window:
lspci -nn -d 14e4:
then look at the table on this page to identify the device: https://wireless.wiki.kernel.org/en/users/Drivers/b43#Supported_devices
August 27, 2016 at 2:46 am #48101Empty output from that last lspci command.
The device is an bcm4343 on sdio. My suspicion is that the I2C bus responsible isn’t detected, hurting touchpad, the second microsd slot and wifi/bt.
August 27, 2016 at 2:52 am #48102What’s the output of that lspci command? The 4343 is not listed on that page so perhaps it’s not yet supported.
August 27, 2016 at 8:23 am #48119The output of this command is empty. Here is the output of the command without the end

I think this needs to be reported to the Linux wifi device dev’s so it can be added to the driver. I notice there are a handful of Broadcom b/g/n SDIO devices with similar name. Are you sure it is BCM4343?

BCM43431 PCIEAugust 27, 2016 at 3:45 pm #48174I think you guys already covered this, but just encase:
https://wiki.debian.org/bcm43xx#ndiswrapper
NDISwrapper
This should only be used as a last resort, if the device is not supported by Linux kernel drivers (e.g. Broadcom USB devices, other than the BCM4320).Blacklist Linux kernel drivers
If loaded, the b43/b43legacy drivers will conflict with NDISwrapper. To unload and blacklist:
modprobe -r b43 b43legacy
echo -e blacklist b43\\nblacklist b43legacy >> /etc/modprobe.d/local.conf
InstallationKernel module and NDIS driver installation is described on the NDISwrapper page.

August 27, 2016 at 3:55 pm #48175What is the output of running this terminal command. I’m assuming nothing shows up for Wireless?

BCM43569August 27, 2016 at 4:46 pm #48181There is currently only this firmware file (brcmfmac43430-sdio) so it could be just a matter of installing this and configuring it for the 4343 (note not 43430):
[edit] I’m running kernel 4.8 and in my /lib/firmware/brcm folder I don’t have the firmware file (brcmfmac43430-sdio.bin) or config file. I think you must download them, not sure where, maybe here (https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm80211/brcm)https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm80211/brcm
Found this as of August 6, 2016 which I interpret that a firware download and install is needed:
https://www.spinics.net/lists/linux-wireless/msg153265.html
Hi,
I managed to get Wifi working on a imx7 warp board, which has a BCM43430 device.
I used the firmware from the RaspberryPi repository:
https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm80211/brcmAre there any plans to make brcmfmac43430-sdio.bin available in the
official linux-firmware repository?Thanks,
Fabio Estevam
August 27, 2016 at 5:34 pm #48186It may be instructional to see how Wifi is enabled on the Asus T100TA which also uses a Broadcom SDIO wifi device:
https://wiki.debian.org/InstallingDebianOn/Asus/T100TA#WiFiWiFi
The wifi device is an on-board SDIO device Broadcom 43241b1, firmware and nvram file need to be installed.
The firmware can be installed with the package firmware-brcm80211 from the debian repository, download it and install it. If you have a way to access to the internet, like a wifi dongle, simply use the package manager to install it.
The nvram file can be found under /sys/firmware/efi/efivars/. If the directory is empty it may need to be (temporarily) mounted first by:
# mount -t efivarfs efivarfs /sys/firmware/efi/efivars
Then the nvram-file needs to be copied and renamed:# cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43241b4-sdio.txt
If this does not work on T100TAL, try:# cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcm/brcmfmac43340-sdio.txt
In general, you can determine the name of the target file looking at the output in the /tmp/var/syslog after you restart the brcmfmac module:brcmfmac_sdio mmc1:0001:1: firmware: failed to load brcm/brcmfmac43340-sdio.bin (-2)
Note that brcmfmac43241b4-sdio.txt (and other) contains a wrong MAC address. However this is not a problem and does not need to be changed as the file is only a template.After that reboot the system or reload the brcmfmac module:
# modprobe -r brcmfmac
# sudo modprobe brcmfmacAugust 28, 2016 at 2:39 am #48263Sorry, I didn’t mean to mislead anyone about the touchpad… Multi-touch (only multi-touch – no single-touch) on the touchpad was/is working on my ezbook 2 and I assumed it was because I had played with the kernel config options. But I realized after that multi-touch (tap three fingers on the touchpad and the start menu will appear) on the laptop was always working even by default on the Manjaro kernel, so I got pretty depressed about getting linux to run. On top of that, I realized that battery status wasn’t always working, so that meant battery, touch, audio and wifi wasn’t working so I gave up and just went back to Windows, and stopped vising this thread. I was also very busy at the time. I assumed this thread was dead… didn’t realize there are this many people trying to run linux on this laptop.

BCMSDH43XX_Service_DispName=”Broadcom 802.11 SDIO Network Adapter Driver”August 30, 2016 at 3:46 am #48429I found a workaround for the battery in this [bug report](https://bugzilla.kernel.org/show_bug.cgi?id=88471).
I can get the battery percentage on linux but it’s a really hacky method. I started with linux v4.4 in Manjaro Linux. I downloaded kernel v4.8-rc4 from github (https://github.com/torvalds/linux/releases). I outputted the kernel config to file by doing
zcat /proc/config.gz > ~/Downloads/linux/.config
and then I ranmake olddefconfig
inside ~/Downloads/linux. Then I ranmake xconfig
and I set the following options: http://imgur.com/a/tEDbx. Also, I2C_DESIGNWARE_BAYTRAIL needs to be set to N (or else the battery stats will not work). I then compiled the kernel, rebooted and ran the following script: https://github.com/tgharib/axpd to get the battery percentage. The i2cget call seems to crash the laptop ~1/16 times, so do not call it too many times per laptop session.Also, before running the script you need to have i2cget installed. On Manjaro, run
sudo pacman -S i2c-tools
.August 31, 2016 at 6:03 pm #48527@BBaker: I installed the BCM43430 firmware in /lib/firmware/brcm/ and loaded brcmfmac module but nothing happend. Since it’s a SDIO device, it uses the SD card interface so I think we have to get the SD card reader working first. According to this [thread](https://github.com/hadess/rtl8723bs/issues/20), you have to probe SDIO devices using /sys/bus/sdio/devices/ (not lspci) and if there is nothing there, then the OS cannot see the SDIO device. There is nothing in that directory for me.
