And you can confirm what sh is configured as by doing:

ls -l /bin/sh

It will typically either be a symlink to bash or dash.

Re: [beagleboard] Ubuntu 13.10 NO GUI (NO graphical user interface)

Search the forum. This question was answered two hours ago. Just type GUI
in the box and sort by date.

You have to install the GUI yourself.

[beagleboard] Ubuntu 13.10 NO GUI (NO graphical user interface)

[danushkaj91]

*Hey There.. *

*I followed this procedure and installed Ubuntu 13.10 in my BBB. Used the 
prebuilt image.** 
(https://rcn-ee.net/deb/flasher/saucy/BBB-eMMC-flasher-ubuntu-13.10-2013-11-15.img.xz
 
)*

*It was successful, but after installing it Im getting only a command line 
interface. Can I get a GUI somehow? Or is there a image with a GUI ???*


Flasher[edit
]
eMMC: BeagleBone 
Black[edit
]

This image can be written to a 1Gb (or greater) microSD card, via 'dd' inlinux 
or the win32 image program linked to on CircuitCo's wiki page. First hold 
down on the boot select button (next to microSD card) and apply power (same 
procedure as the official CircuitCo images), it should boot into Ubuntu and 
begin flashing the eMMC, once completed all 4 LED's should be full ON... 
Simply remove power, remove microSD card and Ubuntu will now boot from eMMC.

Script for Reference: (this is the script that writes to the eMMC)https:
//github.com/RobertCNelson/tools/blob/master/scripts/beaglebone-black-copy-microSD-to-eMMC.sh

BTW: we are only writing about 500Mb's to the eMMC so the script will only 
take about 5-6 Minutes after power on.

Notes:
If only two LED's stay lit and nothing happens, the board has crashed due 
to lack of power. Try with a 5Volt DC supply plugged in..
If the 4 LED's blink a constant pattern, eMMC write failed, first REMOVE 
ALL capes, then retry again.

Re: [beagleboard] Re: Need I2C drivers for lcd for ebay

[Dave Hylands]

Hi Jim

So I looked at a variety of other i2c based LCD codes (there seem to be
lots for the Raspberry Pi), but I didn't like them.
So you can try mine.

You can do the following on the BBB:

git clone https://github.com/dhylands/python_lcd.git
cd python_lcd
sudo pip install -e .
sudo python lcd/i2c_lcd.py

Running i2c_lcd.py runs some test code which puts some stuff up on the LCD,
and after 3 seoncds shows the current data and time and then cycles through
a variety of backlight/display on/off combinations.

I used a 3.3v to 5v level shifter.

I wound up using smbus directly rather than the Adafruit_I2C (but
installing Adafruit_I2C will install smbus)

I threw some photos together here:
https://picasaweb.google.com/115853040635737241756/PythonI2CLCD?authkey=Gv1sRgCLyZoJ3_uPjiXA#

Coming from the BeagleBone Black the wire colors are:
Black: P9-1 GND
Red: P9-3 3.3v
Orange: P9-5 5v
Yellow: P9-19 SCL
White: P9-20 SDA

And the colors going to the LCD are:
Black: GND
Red: 5v
White: SDA
Yellow: SCL

[beagleboard] Ubuntu flash/boot problem

[danushkaj91]

hey guys,

I'm having trouble with flashing/booting with Ubuntu on my BeagleBone Black 
(BBB)

1. I downloaded the Ubuntu 13.10 *xz* file through 
armhf, 
extracted using* 7Zip *(got a img file)*, *and copied to *micro sd *using* 
win32 disk imger*
2. Inserted memory card while BBB is powered off, and switched it *on *while 
holding 
the *boot *button. Released the *boot* button when user LED was lit.
3. login screen came after 1-2 minutes.
3. waited for *all LED*s to be *stabled*. *But they never did*. ..

*When I remove my memory card, BBB won't get switched on either.  *

Am I missing something?

Re: [beagleboard] Failure to re-flash Beagle Bone Black

[Gerald Coley]

Create a uSD card that successfully flashes the other board again.
Then try it on this board..
If it fails, then request an RMA and we can look at to to see what is going
on.

Re: [beagleboard] Failure to re-flash Beagle Bone Black

[mikeyang75]

Thank you for your reply. To answer your questions:
- Yes, I am unzipping the image that was loaded prior to putting it on 
sdcard
- Nothing else is plugged in. Only SDcard and 5V brick are plugged in
- The brick is rated at 5V, 2Amps
- I have formatted the SDcard but not consistently. I will try again.

Note: The SDcard I am using is a SanDisk 8 GB class 4 card. It has been 
used successfully to re-flash (un-brick) a different BBB, although I am 
using a different image.

Re: [beagleboard] Failure to re-flash Beagle Bone Black

[Gerald Coley]

Are you unzipping the image that you download?
Make sure nothing else is plugged in, no HDMI and no Ethernet.
Make sure 5V power supply can deliver at least 1A.
Reformat the uSD card before you use Windisk to copy the image onto the 4GB
card.

[beagleboard] Failure to re-flash Beagle Bone Black

[mikeyang75]

Greetings,

I have a Beagle Bone Black (BBB) that I somehow managed to brick and I have 
been following the instructions on these two sites to try and re-flash the 
image:
http://elinux.org/Beagleboard:Updating_The_Software
http://learn.adafruit.com/beaglebone-black-installing-operating-systems/overview

I am using a Windows 64-bit PC to connect to the BBB and I am using the 
image titled "BBB-eMMC-flasher-2013.09.04.img.xz" which I downloaded from 
here: http://beagleboard.org/latest-images/

I have tried multiple times to re-flash my BBB but so far nothing seems to 
work. I am following the directions which are to 1) put image on sdcard, 2) 
put sdcard in slot, 3) hold down user boot button, and 4) turn on BBB by 
plugging in a 5V power brick, 5) release user boot button when all 4 LEDs 
are on. Every time I do this, I told the user boot button down until all 4 
LEDs light up solid and then start flashing, at which point I release the 
button. I wait 45-60+ minutes (one time I let it go overnight) but at no 
point do I end up with an indication that the re-flash is complete (i.e. 
all 4 LEDs lit up solid). During the re-flash process (or what I assume is 
the re-flash process), the LED's look like this:
LED 0 - heartbeat, which indicates system is running
LED 1 - Nothing. This corresponds to access of the microSD card
LED 2 - Blinking. This corresponds to an active CPU. 
LED 3 - Nothing. This corresponds to access of on-board memory

I have tried plugging in an HDMI cable so that I can view what is happening 
during the re-flashing process. Upon bootup, the monitor shows a BeagleBone 
flash screen followed by a login screen. By using a USB-connected keyboard 
I can log in as "root". It does not ask for my password even though I had 
created a password for my pre-bricked BBB. Once logged in I can navigate 
through different directories, manually turn on/off LEDs, etc. Note that 
the login screen only appears if I have an sdcard in the BBB. Without the 
sdcard, the BBB will have the power LED on, but will not respond, nor will 
it connect to PC, nor will any of the other LEDs come on. Also note that it 
does not appear to matter if I press the user boot button or not... the BBB 
seems to always boot from the sdcard if it is plugged in. 

I'm at the point where I am about ready to throw away this BBB and buy 
another. However, I would prefer to solve this mystery if possible. Any 
suggestions would be most welcome. If you have any follow-up questions I'd 
be happy to answer them.

thanks!
Mike

Re: [beagleboard] HDMI is not working at all

[Gerald Coley]

Did you check for the troubleshooting section on the support Wiki?

http://www.elinux.org/Beagleboard:BeagleBoneBlack  Look under HDMI.

DRM does not use the optargs. It only uses the EDID information it reads
form the display  to set the resolution.

[beagleboard] HDMI is not working at all

[rianovich96]

Hi friends,

Very disappointed... after several hours of trying, the HDMI output is not 
working.
The board has latest flash image 2013.09.04 as shipped, no modifications, 
no booting from SD.

In fact, I have nothing in 

cat /proc/cmdline

root@beaglebone:~# cat /proc/cmdline
console=ttyO0,115200n8 quiet drm.debug=7 root=/dev/mmcblk0p2 ro rootfstype=ext4 
rootwait

where is the video argument?

I've tried all things kindly explained by this guy here:
http://bb-lcnc.blogspot.ro/2013/06/force-beaglebone-black-hdmi-resolution.html

I use a reasonable HDMI to VGA adapter:
http://www.delock.com/produkte/G_65347/merkmale.html?setLanguage=en

I even tried to pass arguments to u-boot but they don't appear after booting 
process
cat /proc/cmdline

setenv optargs video=HDMI-A-1:640x480@60

Any idea please ?!

ok, here I am, downloaded the new image, extracted to my mSD card, 
inserted into the BBB mSlot, powered the BBB (while pressing boot

I finally tested quickly aseqnet with no errors (connections only). Only 
snd-virmidi module is missing.


For me it is quite enough, it's ok, strange that to use alsa-utils

with to Debian's paranoya about security issues.


well done, Robert, thank you!

Hi,

I just tried updating to v3.12.5-bone10 (from
http://rcn-ee.net/deb/saucy-armhf/v3.12.5-bone10/), but my BBB froze
completely shortly after booting. Unfortunatly, there was absolutely

have changed between v3.12.4-bone9 and v3.12.5-bone10...

[beagleboard] Re: problem in BBB

[sask1236]

Hello,

We dont have to type the IP address there if the communication is 
successfully established by BBB.
I had one BBB which directly communicated and turned the image green as 
shown in pic.
But on another board i was not able to communicate with it on Windows Putty 
or from linux ssh. After reading forums i got to now that some BBB images 
are broke and so they dont communicate on putty and so your step 3 is not 
done.
Install a fresh image of Angstrom in your board. All will work fine. I have 
done it for myself.

Have a look at the PRU, there are two of them built into every BBB (in 
the CPU chip), they provide all you need for the real time bits and 
then you can do the non-real time bits under normal linux on the main 
CPU.

Using the PRU you can access IO pins, and they have timers too.

HI Alessandro,

Not sure if I understand your question, but since Gerald answered the
hardware side, here is the software answer. The interrupt latency in the
Linux Kernel doesn¹t make it suitable for real-time applications, but if you
patch the kernel with Xenomai, then you can achieve interrupt latencies of
about 50uS.

John

There is a problem with the USB host driver, so hotplugging does not 
work.   
Started a crowdfunding project for the fix.

There is a problem in the driver, which I noted when I tried hotplugging.
With my fix, I can hotplug a mouse, keyboard, USB serial and a hub, do not 
know if my fix solves your problem though.

If the host driver can be built as a module, then rmmod might work (didn't 
check).
You are aware that the USB host has hotplugging issue?

Hey, did you try another power supply? Probably the PS has problem 
supplying the current and drops voltage? Or there is a current limitation. 

I tried to reproduce by only connecting P9.5, P9.6 and P9.1 (GND) , but 
could not.

[beagleboard] dcan1 on BBB only transmits data when loopback mode is enabled and also does not receive data

[x . ample]

Hi all,

we bought a BBB a few days ago. I tried to run a simple can send/receive 
demo. I'm using the "out of the box"  angstrom linux distribution and 
activated the dcan1 according to this tutorial: 
http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/ . 
The overlay is placed and the driver comes up as expected. My ifconfig 
shows the can0 if and I could start a simple onboard loopback demo. Now we 
ordered a HS-CAN transceiver (microchip MCP2551) and setup a simple 
circurit and connected the CAN bus to an external stimmulator. Now to my 
problem: I only can send data on the bus (even on the relatet pin on BBB) 
when I initialize the CAN with loopback mode enabled, otherwise only the 
first frame can be seen via a oscilloscope but the bus tracer reports an 
error. All attempts to write again on the bus fail afterwards. Dmesg tells 
me "c_can_platform 481d.d_can can0: setting BTR=1c0e BRPE=".

The next problem is, when I start in loopback mode, I only can send on the 
bus, but when I trigger a frame with the external bus stimulator I can see 
the frame circulating on the bus (again only with the oscilloscope) but no 
reception at the RXD pin of my BBB.

Does this sound familar to any one? Thank you in advance

Re: [beagleboard] BeagleBone Black: is it a Real-Time Board?

Correct. The HW design does not
use industrial temperature devices, although there are a lot of people that

Re: [beagleboard] BeagleBone Black: is it a Real-Time Board?

Hi,

Linux is per default not a real-time OS, but you can turn it into a "firm" 
real-time OS using for example the PREEMPT-RT patch. However, you will 
still not the kind of absolute guaranteed latencies you would be able to 
get from a dedicated real-time OS.

If you need a real-time OS I think at least QNX should be supported on the 
BBB;

http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/TiAm335Beaglebone

Gerald, I assume you are answering from the perspective of the capabilities 
of the Sitara ARM SoC and there I agree that it is capable of industrial 
control systems. However, Alessandro asks if the BBB can be used for 
critical applications in industrial environments. I wouldn't call the HW 
design of the BBB "rugged" like what you would expect to see in those 
environments. After all, it is a $45 computer... Using the BBB to prototype 
those applications is likely OK, but I would recommend a rugged HW design 
to put such a system into operation in critical industrial environments.

[beagleboard] How Difficult is it to Compile and Run Robert Nelson's Ubuntu 13.04, V3.12.x branch?

[Bit Pusher]

Not! Just for info, especially for newbies (which I am regarding linux 
kernels). I went through the process of downloading and compiling
Robert Nelson's Ubuntu 13.04 (v3.12.x branch (better usb and ethernet)), 
and it was very seamless and straightforward with no
glitches. What a nice piece of software, one of the cleanest installations 
I have encountered (although again, I am a newbie here).
It connected through the ssh on the ethernet first try. Thanks Robert; 
highly appreciated.

[beagleboard] BeagleBone Black is a Real-Time Board?

[guerreski]

Hi all,

I would like to know if the BeagleBone Black is a Real-Time Board, that 
allow it to be used also in industrial applications.

Normally I always used microcontrollers to elaborate signals, I am 
wondering if also the BBB can have the same reliability and Real Time 
properties (that assures a certain maximum instruction time).

Hi Dave,

Thanks for your answer.

I have reconfigured sh using: sudo dpkg-reconfigure dash.
But I received the same error.

What can it be?

[beagleboard] Re: Edma 2channel transfer loop

[Dimitris Boulougaris]

Hi Terrence.

Yes i am writing a kernel module and interfacing with it from user space.

As i went through the same period like you do now i'll be glad to help you.

The first step is to allocate the buffers that the edma will use
 source and destination buffers as well . as edma needs special buffers.
The second step is to allocate the channels you want.
Then comes the configuration of the transfer of each channel.

As you can understand i cant describe the hole process in detail as edma
and its applications are quite complicated.
if you can be more specific ill be glad to give you more specific
information.

[beagleboard] BeagleBone Black: is it a Real-Time Board?

[guerreski]

Hi all,

is it possible to use the BeagleBone Black as a Real-Time board, that 
allows it to be used for critical applications, like in industrial 
environment?

Thank you very much!

[beagleboard] Re: BeagleBone Black USB Host hot plugging issues

[rick93nl]

Nevermind I now know for sure it's the USB device that is causing the issue.
It's a storage device, and it works fine when hot plugging into my laptop.

I plugged another USB storage device into the BeagleBone Black and that 
worked fine.
So the USB device that fails must've become somewhat broken somehow. Not 
broken
enough that my laptop doesn't accept it anymore but broken enough that the 
BeagleBone
Black doesn't accept it. 

This post can be removed.

[beagleboard] NFS server on beaglebone black

[oliche]

Hello,
I managed to run a NFS server on a Beaglebone a couple of years ago by 
simply installing the following module.

*opkg nfs-utils install*

Revisiting the idea with the Beaglebone black I get the following message 
when installing the package
*nfs-utils: unsatisfied recommendation for kernel-module-nfsd*

Unsurprisingly the service then fails :

*root@beaglebone:~# systemctl status nfsserver.service*
*Jan 01 02:18:08 beaglebone rpc.statd[820]: Version 1.2.3 starting*
*Jan 01 02:18:08 beaglebone sm-notify[821]: Version 1.2.3 starting*
*Jan 01 02:18:08 beaglebone sm-notify[821]: Failed to read monitor data 
from /var/lib/nfs/sm.bak/state*
*Jan 01 02:18:08 beaglebone rpc.statd[820]: Failed to read 
/var/lib/nfs/state: Success*
*Jan 01 02:18:08 beaglebone rpc.statd[820]: Initializing NSM state*
*Jan 01 02:18:08 beaglebone rpc.statd[820]: Running as root.  chown 
/var/lib/nfs to choose different user*
*Jan 01 02:18:08 beaglebone rpc.statd[820]: unable to register (statd, 1, 
udp).*
*Jan 01 02:18:08 beaglebone nfsserver[807]: starting statd: done*
*Jan 01 02:18:08 beaglebone systemd[1]: Failed to start LSB: Kernel NFS 
server support.*
*Jan 01 02:18:08 beaglebone systemd[1]: Unit nfsserver.service entered 
failed state*

Trying resuscitation :
*root@beaglebone:~# /etc/init.d/nfsserver start*
*creating NFS state directory: done*
*starting 8 nfsd kernel threads: rpc.nfsd: Unable to access /proc/fs/nfsd 
errno 2 (No such file or directory).*
*Please try, as root, 'mount -t nfsd nfsd /proc/fs/nfsd' and then restart 
rpc.nfsd to correct the problem*

Then kindly trying to make sense out of the error message
*root@beaglebone:~# mount -t nfsd nfsd /proc/fs/nfsd *
*mount: unknown filesystem type 'nfsd'*

It seems pretty clear that something called "nfsd" is missing, but I can't 
figure out what is needed to get it. Apparently it is not a package.

Any advice welcome.
Thanks.

Re: [beagleboard] Boot a Custom board based on similar design as Beaglebone Black

[nitesh singh]

Thanks a lot Robert Sir.

I was able to boot the board using Emmc flasher image of angstrom and then 
I am now able to use sd cards and boot from them. 
But the EEPROM is still blank, I think I can write the eeprom now from 
uboot shell. 

Issues that i have seen when i have booted with normal uboot image from the 
sd cards (with emmc written by emmc flasher image earlier) is that on 
'lsblk' , I only see the sdcard blocks as following

NAMEMAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
>
> mmcblk0 179:00   3.7G  0 disk
> ââmmcblk0p1 179:1048M  0 part /boot/uboot
> ââmmcblk0p2 179:20   3.6G  0 part /
>
> And I cannot apply any device tree overlays, actually the slots file is 
missing from  /sys/devices/bone_capemgr.9/ 

What could be the possible reasons ?
I am attaching the UART0 output for the same beaglebone black while I was 
booting with sd card.
