Bringing up WiFi interface on Wandboard Quad

[bcattle]

I'm having issues getting the WiFi interface working on the Wandboard Quad. I try to bring up the interface with

$this->bbcode_second_pass_code('', '
root ~ # ip link set wlan0 up
RTNETLINK answers: Operation not permitted
')

And the driver spews a bunch of error messages into the kernel log

$this->bbcode_second_pass_code('', '

The interface boots successfully and wlan0 shows up in "ip link" and "ifconfig -a". I'm using kernel version 3.10.17-2-ARCH.

Any idea what's going on? Is there anything more I can test to figure out what the problem is? Thanks.

Looks like the issue is a device tree modification is needed to support rev C1 board. See here: http://forums.wandboard.org/viewtopic.php?f=8&t=440&sid=b49b7de10d696605c91630681bd9767a#p2079

May I ask how I can use the build system you're using to patch the kernel and build a package? I'd like to give it a go on my wandboard. How do you identify the version of the board?

When you upgrade to the latest stock kernel (linux-wandboard to 3.10.17-3) The new device tree and rfkill are available. it auto-senses which board you have.

To see which board you have, read the line between the heatsink and the EDM connector. Mine reads "WB-EDM-iMX6 REV C1". I deduce from this that i own a rev C1.

Make sure you have all the firmware installed. you need both the packages linux-firmware and firmware-brcm43xx.

Expect your wlan to drop out (not waking up) after a period of inactivity. The modification still needs some work. there are several threads about this. You can prevent this from happening by pinging the board once a minute. (ping -c 2000 -i 60 X.X.X.X)

Well, then, install the latest kernel, make sure you installed the two firmware packages and reboot.
You should be golden. AFAIK there are no problems with the bcm 4329 chip.

With this setup you make sure that the kernel modules and the firmware fit. (names, locations etc)

If you want to use bluetooth too, you need to run "sudo systemctl enable brcm43xx" before you reboot.

By latest kernel you mean mainline? i.e. linux-armv7? I'm about to flash u-boot and install that.

[PLyttle]

no, the linux-wandboard kernel package, like mentioned before (linux-wandboard 3.10.17-3)

sudo pacman -S linux-wandboard

I installed linux-armv7 and it worked! Slightly more stable it seems, no more kernel debug error messages in dmesg.
