BeagleBone USB Wireless Adapter Configuration

I'm relatively new to Linux in general so if I'm missing something
obvious please let me know. Here's how far I've gotten to getting this
working:

1) I bought an EDUP EP-MS150ND wireless adapter because it was cheap
and said that it supported Linux. When I plug it into the BeagleBone I
can get the following:

root@beaglebone:/etc# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 148f:5370 Ralink Technology, Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So, it looks to me that it using the RT5370 chip set from Ralink. I've
downloaded the drivers from the following locations:

http://www.edupdriver.com/
http://www.ralinktech.com/en/04_support/support.php?sn=501

However, when I try to build them on the BeagleBone it seems like
there are some source files that its expecting to be there that don't
come with the demo image. I haven't learned enough yet to know how to
build these, so any help on that point would be appreciated, too.

2) Here is the configuration I have so far:

From /etc/network/interfaces:

# Wireless interfaces
iface wlan0 inet dhcp
        wireless_mode managed
        wireless_essid any
        wpa-driver wext
        #wpa-driver hostap
        wpa-conf /etc/wpa_supplicant.conf

From /etc/wpa_supplicant.conf:
#/etc/wp_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
     ssid="redacted ssid name with spaces"
     scan_ssid=1
     proto=RSN
     pairwise=CCMP TKIP
     key_mgmt=WPA-PSK
     #psk="redacted plaintext psk"
     psk=[redacted binary psk generated with wpa_passphrase]
     priority=1
}

3) When I do an ifup wlan0 I get the following:

root@beaglebone:~# ifup wlan0
[ 3529.012747] phy0 -> rt2x00lib_request_firmware: Error - Failed to
request Firmware.
Could not set interface wlan0 flags: No such file or directory
Failed to initialize driver interface
[ 3529.054802] phy0 -> rt2x00lib_request_firmware: Error - Failed to
request Firmware.
ifconfig: SIOCSIFFLAGS: No such file or directory

It seems to be there when I do an ifconfig -a though:

wlan0 Link encap:Ethernet HWaddr [redacted MAC address]
          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)

Can anyone offer any advice? Thank you in advance for any help!

You need to get the firmware file and put it in /lib/firmware/rtlwifi/
rtl8712u.bin. I downloaded it from somewhere, but I can't recall
where.

I have a REV C Beagleboard and the demo image shipped with the unit would not allow us to use CMEM without barfing. As such, I have downloaded a image and no matter what I try it hangs indefinitely at

[ 3150.767059] usb0: link up, 100Mbps, full-duplex, lpa 0x45E1

Pinging causes this. I am trying to build a video streamer. The basic image boots fine but then I have all these packages to install.

[ 3697.230651] Alignment trap in kernel: swapper (0) PC=0xc043a2d4 Instr=0xe8930003 Address=0xdf08802a FSR 0x001

I was under the impression that all this Angstrom stuff is at least stable? I cannot get past this point no matter what I try and I am at a point, after messing for a month with another OMAP board, that this stuff will not work. I have no desire to build new kernels, I have a specific goal and I am deeply frustrated at how difficult this has been to get a fully functioning platform…

I downloaded the files from the following location:

http://packages.debian.org/sid/firmware-realtek

I just copied the entire contents over to the BeagleBone SD card, but
it still does not work.

root@beaglebone:/lib/firmware/rtlwifi# ls
rtl8192cfw.bin rtl8192cufw.bin rtl8192defw.bin rtl8192sefw.bin
rtl8712u.bin

root@beaglebone:/lib/firmware/rtlwifi# ifup wlan0

Failed to initialize driver interface
[ 113.494436] phy0 -> rt2x00lib_request_firmware: Error - Failed to
request Firmware.
ifconfig: SIOCSIFFLAGS: No such file or directory

Are there any additional steps that I need to take to tell the OS
where to look for the file.

Also, how could I tell which firmware file name it's looking for.
"Realtek" is not "Ralink" so I wouldn't have though to try these
files. Educate me please! :slight_smile:

Thank you for any help in advance!

Sorry, I didn't read your post carefully. Yes, ralink is different
from realtek. I guess the ralink firmware would be named something
like rt****.bin. I see a bunch of them in /lib/firmware/ on my Fedora
system.

I had an Ubuntu 11.10 system handy and copied the entire /lib/
firmware/ folder over to the BeagleBone taking care not to overwrite
the files that were already there. I got the following:

root@beaglebone:~# ifup wlan0
[ 72.140395] phy0 -> rt2x00usb_vendor_request: Error - Vendor
Request 0x07 failed for offset 0x1340 with error -110.

Request 0x06 failed for offset 0x1608 with error -110.
^C
root@beaglebone:~#

The error message just continues coming up though. I tried ifconfig -a
and it hung and I'm getting the following periodically...

[ 1200.160395] INFO: task ifconfig:308 blocked for more than 120
seconds.
[ 1200.167293] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs"
disables this message.

And I can't get back to the command prompt at this point... back to
the drawing board. Fortunately I have an SD card reader and can fix
it.

I'll see what it takes to get the wireless adapter running on the
Ubuntu machine and post back. Jump in if you have any other ideas!

I cracked open the USB dongle and confirmed that the chip set used was
indeed the Ralink RT5370. There was some confusion online about the
chip set used for this manufacturer part number. It appears that the
manufacturer had used other chip sets (including Realtek) for the same
part number, but the Ralink RT5370 is definitely what I have.

So, I proceeded to successfully build and install the drivers on my
Ubuntu 11.10 machine as follows:

1) make the following edits to /os/linux/config.mk
   HAS_WPA_SUPPLICANT=y'
   HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

2) sudo su

3) make

4) make install

5) modprobe rt5370sta

6) ifconfig -a

7) iwlist ra0 scan

...

So, now back to the BeagleBone... When I try to reproduce this on the
BeagleBone I get the following:

Looking at this file location, I see the following...

I created the folder and tried again...

This is how far I've gotten... I'm open to any words of wisdom. Thank
you again.

In /lib/modules, "build" is usually a symlink to to the kernel source
in /usr/src. I don't see it packaged, but you can get it from
kernel.org.

9

I decided to give cross-compiling the module on my Ubuntu machine a
shot.

I started off getting the Angstrom SD card image to build to confirm
that things are working:

Install Bitbake from the Ubuntu Software Center
sudo apt-get install build-essential
sudo apt-get install diffstat
sudo apt-get install texi2html
sudo apt-get install texinfo
sudo apt-get install gawk
sudo apt-get install chrpath
sudo apt-get install lzop
mkdir angstrom
cd angstrom
git clone git://git.angstrom-distribution.org/setup-scripts
cd setup-scripts
git checkout origin/oe-core -b oe-core
./oebb.sh config beaglebone
MACHINE=beaglebone ./oebb.sh bitbake systemd-image
MACHINE=beaglebone ./oebb.sh bitbake virtual/kernel

I was also able to use Bitbake to compile a simple "Hello, World!"
application that was was able to load and execute on the BeagleBone.

So I tried to build a Bitbake recipe around the Makefile for the
driver build. Here it is:

DESCRIPTION = "RT5370 Kernel Module"
SECTION = "kernel/modules"
PRIORITY = "optional"
LICENSE = "CLOSED"
RDEPENDS = "kernel (${KERNEL_VERSION})"
DEPENDS = "virtual/kernel"
PR = "r0"
SRC_URI = ""
S = "${WORKDIR}"
inherit module

When I run it I get the following:

It appears that it isn't copying the source from the source folder to
the build folder. But I'm still trying to figure out the problem. I'm
sure it has to do with the SRC_URI value, but even when I specify the
Makefile, it doesn't seem to get copied.

Thanks for any input anyone can offer!

I copied the kernel source generated when I built the SD card image to
the BeagleBone from the following folder:
/home/jerrill/projects/angstrom/setup-scripts/build/tmp-
angstrom_2010_x-eglibc/sysroots/beaglebone/kernel

and created the /lib/modules/3.1.0+/build symlink to /usr/src/linux.

Also there were a couple of binaries that wouldn't run on ARM and
needed to be rebuilt as well because they were apparently built on the
Ubuntu machine, but that was fairly trivial using gcc. make complained
about them and I fixed them as they came up.

At any rate, I was FINALLY able to build the driver on the BeagleBone
board to get the rt5370sta.ko file I needed. I successfully used
modprobe rt5370sta to install the module.

Now, for the next problem...

Immediately following a reboot without the wireless USB adapter
plugged in, I get the following:

root@beaglebone:~# lsmod

Module Size Used by

g_mass_storage 24072 0

ipv6 209417 14

root@beaglebone:~#

After inserting the wireless USB adapter, I get the following:

However, I still get the following:

root@beaglebone:~# ifup wlan0

root@beaglebone:~#

So, it looks like it's still loading the wrong driver for the device
IN ADDITION to the correct one. This is the next problem I have to
educate myself on how to resolve. If anyone has any advice on where to
head to resolve this to save me some searching and self-education I'd
appreciate it. If not, I'll report back when I get it figured out to
hopefully save someone else a few days worth of work.

Thanks in advance.

You could try deleting the driver that you don't want from the
filesystem. I got to the point of doing that in my saga trying to get
the Realtek driver to work. After compiling a different one it was
still loading the old one, so I deleted it. Unfortunately that's when
my bone totally croaked and I had to send it back. I haven't had the
time or the energy to get back to it yet.

It turns out that there were multiple entries for the VID PID of my
USB device showing in /lib/modules/3.1.0+/modules.alias.

I created a blacklist file to prevent the rt2800usb driver as follows:

root@beaglebone:~# cat /etc/modprobe.d/blacklist.conf
blacklist rt2800usb
root@beaglebone:~#

Now, lsmod show the following after I insert the USB wireless adapter:

root@beaglebone:~# lsmod
Module Size Used by
rt5370sta 566248 0
g_mass_storage 24072 0
ipv6 209417 14
root@beaglebone:~#

However, the device still didn't show up in ifconfig -a. I checked
dmesg to see what happened after I inserted the device. Here's a diff
of the pre-insert and post-insert dmesg notifications:

So close! Yet, so far away!

I had to reduce the size of some of the buffers to get the module to
load. Here's a diff file of the changes I made.

root@beaglebone:~/drivers/wlan/rt5370/include# diff rtmp_def.h
rtmp_def.h.orig

< #define TX_RING_SIZE 4 /* 1 */

hi jerill,
I’m new in linux especially BeagleBoard
I have BBxM rev C installed with angstrom kernel 3.0.4+ and want to enable wireless adapter TP-Link TL-WN321G
but till now i couldnt do that, I begin to feel pain in my head now,

when I type ifconfig, it yields nothing for wlan,
and when I try to ifup wlan0, it shows :

Error for wireless request “Set Mode” (8B06) :
SET failed on device wlan0 ; No such device.
Error for wireless request “Set Frequency” (8B04) :
SET failed on device wlan0 ; No such device.
Error for wireless request “Set ESSID” (8B1A) :
SET failed on device wlan0 ; No such device.
SIOCSIFADDR: No such device
wlan0: unknown interface: No such device
SIOCSIFNETMASK: No such device
SIOCGIFADDR: No such device
SIOCSIFBROADCAST: No such device
wlan0: unknown interface: No such device
Failed to bring up wlan0.

it seems, angstrom couldnt generate the usb wireless.
thank you very much for your helping

It looks like you don’t have a driver on your system that supports your wlan card or that it isn’t configured correctly.

Run lsusb to get the VID:PID of your device. In my case it’s 148f:5370.

lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 148f:5370 Ralink Technology, Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

You need to determine if a driver compatible with your device is on your system via the modules.alias file.

cat /lib/modules/3.2.14/modules.alias | grep “v148Fp5370”

alias usb:v148Fp5370ddcdscdpiciscip* rt2800usb

NOTE: Your folder names may be different if you haven’t updated lately.

My system tells me that this VID:PID is supported by the rt2800usb module. I tried to make this module work, but wasn’t ever successful. I ultimately cracked open the device, got the chip set ID, went to Ralink’s website and downloaded the linux drivers specific to my device and learned how to build it. I had to blacklist the rt2800usb driver because it kept trying to load that one instead of the other when I inserted the usb wlan device.

The ultimate goal is to get the CORRECT driver to show up automatically under lsmod when you insert the wlan device after a reboot:

lsmod

Module Size Used by
rt5370sta 566248 0

Once you get that far, then you have to get the network setting configured for your access point. Check back when you get there or if you get stuck on the way.

Hope that helps,
Jerrill

Dear Jerrill,

It looks like you have the driver file I need - any chance you could send me your compiled driver file?

It looks easier than the pain you went through to ‘make it’.,

I can then just do the install. Post here would be useful for all of us running round with the maplin wireless card!

thank you - Andrew

Hi,

I’m also interested by this driver !

Thank you

Hello all,

Is it also possible for me to get a copy of the driver for the Ralink RT5370 for my BBB?

I appreciate it greatly,

Hi Jerril, i compile drivers for rt5370 with a cross compiler, then i have the file rt5370sta.ko. But i don't know what i do. Could you help me?

Hi Jerril, i compile drivers for rt5370 with a cross compiler, then i

sudo modprobe rt5370sta
The do the following to see that it was installed correctly
lsmod
If you see rt5370sta in the list, it was installed correctly.
