[beagleboard] beaglebone automatically boots from sd

[BBBUser]

I have installed Ubuntu in the eMMC of the BeagleBone Black and Debian 
"bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img" on the SD (non 
flasher). 

If I remove the SD card *only *I am able to boot from the eMMC. If I boot 
while the SD is plugged with *no *switched pressed the BBB boots by default 
the SD image. Also if I boot (connect power cable) while holding the boot 
switch *still *BBB boots from the SD card. 

Why does this happen? Has anyone else had this experience?

[beagleboard] Question about Device Tree and GPIOs

[Iñigo Martínez]

Hi,

I have been reading/testing information regarding Device Tree, GPIOs since 
I updated to 3.14, where bone_capemgr.* has dissapaeared, trying to 
understand how everything works. I have been surfing around this board and 
I have some ideas about how it works, but I haven't figured out it yet.

I have attached a proto board and I created the device tree and loaded it 
using the dtb option in uEnv.txt. I think that it's loaded correctly 
because I disabled the can ports and they aren't loaded anymore.

I have the following two paths:

/sys/devices/44e1.control_module
/sys/devices/44e10800.pinmux

And these paths too:

/sys/devices/ocp/*.gpio|.i2c etc... (* = 4030 ... 5600)
/sys/devices/ocp/cape-universal
/sys/devices/ocp/ocp:*.pinmux (* = P8_07 ... P9_91)

And finally regarding GPIOs:

/sys/class/gpio/export
/sys/class/gpio/gpiochip* (* = 0, 32, 64, 96)
/sys/class/gpio/unexport

I can use the GPIOs after exporting them, and the behaviour is correct, so 
as I said, everything looks that works fine.

Questions:

   - Is everything correct this way ?
   - How can I export gpio pins at boot so I have them available ? Is there 
   any option in u-boot/kernel for this ? Should I create systemd service ?
   - I have been reading about beaglebone-black-pinmux and 
   beaglebone-universal-io too, how they fit in this setup ? Is config-pin 
   related with exporting gpios on boot ?


Thank you,

Best regards,

[beagleboard] Re: BBBAndroid: WiFi/DNS Issues with BBBAndroid

[Ankit Chaturvedi]

Hi Keith,

It seems the issue was missing "-g@android:wpa_wlan0" line to 
wpa_supplicant service. Wifi is up and running now, although I still see 
the iptables errors early in the boot. They don't seem to have any effect 
on system stability though so I'll ignore those for now.

Thanks a lot for you help, much appreciated.

[beagleboard] Re: Question about Device Tree and GPIOs

[Nic Cyn]

Hi Inigo

>I have been surfing around this board and I have some ideas about how it 
works, but I haven't figured out it yet.

It is quite a complex topic. I too spent a quite some time trying to figure 
out the Device Tree and once I thought I had an understanding I wrote up my 
notes afterwards. Perhaps you will find the document below provides some 
useful background. Basically its contents are the information I wish I had 
when I was first trying to figure out the Device Tree.

[beagleboard] Ethernet refusing connection

[James S]

I'm using BBB A5A hardware.

I just built a  card with the Debian 8 (Small Flash) kernel using the 
instructions at https://eewiki.net/display/linuxonarm/BeagleBone+Black.
 (With the following exception: Instead of
sudo cp -v ./ti-linux-kernel-dev/deploy/${kernel_version}.zImage /media/
rootfs/boot/vmlinuz-${kernel_version}
I used 
sudo cp -v ./bb-kernel/deploy/${kernel_version}.zImage /media/rootfs/boot/
vmlinuz-${kernel_version}
since ti-linux-kernel-dev directory didn't exist. All instances of 
ti-linux-kernel-dev were substituted.)

It boots fine but the ethernet connection refuses connection. Using the 
serial debug connection, I can ping from the BBB. 
I also get the the following:
root@arm:~# dmesg | grep -i phy

I seen mention of the *0003-cpsw-search-for-phy.patch *here but I think 
thats already applied. (Its in the patches folder in bb-kernel)

It loaded just fine:

davinci_mdio 4a101000.mdio: phy[0]: device 4a101000.mdio:00, driver
SMSC LAN8710/LAN8720

Your issue is elsewhere...

Where are the accesses originating? If they are from a user-space

[beagleboard] bone_capemgr missing in Linux 3.16.0-bone2 BeagleBoneBlack?

[b . sandheep]

I just installed linux 3.16.0-bone2 on my BBB 
fromhttp://www.armhf.com/download/ Im used to work with dtbos and 
/sys/devices/bone_capemgr*/slots in Linux 3.8.x 

So I was surprised to find it missing in 3.16

HOW CAN I FIX IT? Were should  I load dtbos in 3.16?

[beagleboard] BeagleBone: Cross-Compiling Tool-Chain on Mac OS X?

[rei_vilo via BeagleBoard]

I'm trying to cross-compile on my Mac against the BeagleBone.

Surprisingly, the Linaro tool-chain is only available for Windows and 
Linux, not Mac OS X.

The only binary I've found so far comes from 
http://www.welzels.de/blog/en/arm-cross-compiling-with-mac-os-x/comment-page-1/ 
, 
but debugging doesn't work. The sysroots files aren't provided. 

Other options include:

   - Mentor Graphics  —previously Sourcery Mentor 
   — but the 
   tool-chain is no longer free,
   - Carlson Minot  but it doesn't feature 
   hardware FPU, while Debian requires it.

Most blogs suggest to create and host a Linux virtual machine. 

But all tentatives to build the tool-chain myself end with error messages 
and failures. 

Any plan to deliver a tool-chain binary for Mac OS X?

We don't 'provide' any toolchains..

Feel free to ping linaro about mac os x support, or setup a vm..

[beagleboard] Re: beaglebone automatically boots from sd

['dl4mea' via BeagleBoard]

The u-boot programming (see uEnv.txt or stop during boot and say printenv) 
will show you that it first probes if there is a bootable SD card inserted 
and in such a case it boots from SD card.
If you don't want this, you need to change settings in uEnv.txt

Wrong toolchain..

gnueabi =/= armhf...

You need a "gnueabihf" toolchain..

Re: [beagleboard] Stacking Audio Capes for Multichannel Audio Input

[Jeffrey Huang]

We were considering that, but were concerned if we could find a fast enough 
mux to do 6 channels at 48kHz, and that plus clock issues.
Thanks for the idea, though! I will check out how the Am335x fares in TDM.

Re: [beagleboard] Stacking Audio Capes for Multichannel Audio Input

ooh that's pretty cool! Hopefully it will work for me as well.

Did you have to build your own TDM cape, or could you just stack them and 
use the Am335x to do the multiplexing

Re: [beagleboard] BeagleBone: Cross-Compiling Tool-Chain on Mac OS X?

[William Hermans]

Probably the easiest way would be to do as Robert suggests and use a VM.
Virtualbox, and debian works fine. The only obstacle you may run into is
have an sdcard reader recognized in the VM. *if* even needed.

Depending on what you're trying to do, and how you want to do it, a flash
card reader may not even be needed. OSX should have access to better tools
for "flashing" an sdcard than Windows. Then, one would / could just use
various tools over the host only network to transfer files between the VM
and OSX. If just simple executables, sshfs, netcat, and other standard UNIX
tool would work fine to transfer files directly from one system to the
other.

We just used a proto cape to expose the McASP pins we needed, then ran

Re: [beagleboard] Stacking Audio Capes for Multichannel Audio Input

[Jeffrey Huang]

Ah, I see. Thanks for the help! 

My general idea so far is to stack 3 audio capes to receive 6 channel 
input, then process and output probably stereo (or 6 channel out for 
feedback); I guess I'll see how the multiplexing will fit in once I 
understand the board more.

 Thanks for the idea, though! I will check out how the Am335x fares in

Re: [beagleboard] BeagleBone: Cross-Compiling Tool-Chain on Mac OS X?

[Ross Morrison]

I concur, I'm building a 3.8.13-bone71-1 right now on my Macbook Pro OS 
X Yosemite system. I use a Transcend card reader for creating the uSD 
cards from the Linux console in the VM. I've been doing this for 
sometime and everything works fine. I haven't setup a cross dev system 
on the VM yet, but will and expect no problems. The dist/version of 
Linux in my VM is Kbuntu 14.04 32bit. The version of VirtualBox is 
4.3.26 r98988. This is a great way to go if you don't run Windoze. I'm 
strictly a Linux and Apple person and very happy in that respect.

Depending on what you're trying to do, and how you want to do it, a 
flash card reader may not even be needed. OSX should have access to 
better tools for "flashing" an sdcard than Windows. Then, one would / 
could just use various tools over the host only network to transfer 
files between the VM and OSX. If just simple executables, sshfs, 
netcat, and other standard UNIX tool would work fine to transfer files 
directly from one system to the other.

Re: [beagleboard] BeagleBone: Cross-Compiling Tool-Chain on Mac OS X?

[William Hermans]

Well, I use Windows for a Desktop, and have not really had much experience
with OSX hands on. But what I do know is that virtualbox works really well
on Windows, and Virtualbox has binaries for OSX.

I have used those Linaro binaries for Windows by the way, and for simple
applications they seem to work fine *BUT* that whole avenue to me just
seems wrong. Not to mention that it would be very difficult to build the
kernel on Windows, but probably not impossible.

Personally, I think all in all Debian is best for building Debian. But if
you just need to build / compile "simple" applications. Ubuntu 14.04 has
cross tools for armhf that seem to work fine. If needing help setting that
up, just watch DR. Molloy's Videos on youtube from a year or two ago.

Re: [beagleboard] BeagleBone: Cross-Compiling Tool-Chain on Mac OS X?

[William Hermans]

@Ross

I've been building the kernel for the beaglebone black using Roberts eewiki
instructions for around two years now. A lot of that was done from a
virtualbox VM. I've even been using that same vm to load the rootfs for
that A5A over our network.

Anyway, this is not meant as eWenus waggling, just trying to reinforce the
fact that using a Virtualbox VM can work really well. For me, it has been
pretty Rock solid.

Re: [beagleboard] Re: Up, up and away and x15

[William Hermans]

Gerald,

So you mentioned a less expensive board with a single core processor. Is
this the only difference, or do you think there will be other differences
too ? Mostly I'm just wondering if that board would have the same amount of
ddr, which I'm hoping it will.

Can we also assume since that processor will be single core it would have
hald the PRU's, and DSPs ? Or no ?

[beagleboard] USB serial and USB network don't work on new Debian image?

[sbattazzo]

Hello all,

I wanted to put a new Debian image on one of my Rev C BBBs that I have 
sitting around. It seems that the OS boots just fine now (LEDs are blinking 
as usual), but it's now showing up as "Netchip Beaglebone Black" when it 
was something else before (maybe Texas Instruments?) and I can't seem to 
get USB serial or network connection going, whether I have it connected to 
my Windows 7 host or Ubuntu VM.

Does anybody know why that might be? Did something change in the drivers?

Re: [beagleboard] Re: Up, up and away and x15

[Morgaine]

> "Once you stop learning, you start dying"

That sounds depressingly like an obituary, because the main lessons of the
last several years in this space have been that:


   1. Price is king.
   2. The sales/price curve is an exponential over price, and even a poor
   design that's cheap can sell millions.
   3. A SoC slapped onto a PCB with SDRAM and some connectors cannot have a
   high price unless someone is price gouging or their manufacturing systems
   are hopelessly uncompetitive.
   4. There is no shortage of manufacturers of ARM SoCs, so a good engineer
   has a smorgasbord from which to choose.
   5. There is no shortage of good ARM boards, so a high price merely
   ensures that your audience is small or niche, or zero.
   6. Embedded is not a niche market so competition is intense, and
   ignoring the competition is a business deathwish.


These are all very important lessons, and they represent the business
environment of today in ARM boards.  Someone once said "Once you stop
learning, you start dying", and in a business sense that's very true.
Companies either learn and fit into the business environment of the day or
they don't survive.


I very much appreciate my many Beaglebones of both colours, all made by
CircuitCo and not clones, and I was quite inspired along with thousands of
other people by this very effective 2-member series of boards.  But time
doesn't stand still, and it's the right time now for another younger and
even more nimble member to join the family and impress a generation eager
for more IoT devices.


I've read some depressing "There's nowhere to go" comments on this list
resulting from TI's lack of a newer $5 volume SoC to continue the AM335x
family line, but that's just narrow thinking.  There's plenty of room for
new products within the Beaglebone form factor, and it was proven just very
recently by Seeed Studio's newly announced Beaglebone Green
.


There's nowhere to go only if your mind is chained to an existing spec.
All change that improves the ability to meet some embedded requirement that
wasn't well served before should be on the cards for consideration.
Lowering the price definitely fits into that category because it opens up
so many new embedding opportunities, and it's definitely the single factor
which most affects mass adoption.


In summary, I think reports of the end of the BBB line reflect more a lack
of energy for innovation than a lack of possibilities.  For example, a new
and cheaper "BBE" (Embedded-only) could drop HDMI as Seeed did very
sensibly, as well as lose the eMMC.  This would undoubtedly drop the price
significantly since the change of eMMC size from 2GB to 4GB was blamed for
the *rise* in BBB prices.  And with the drop in price will come a rise in
demand (lesson #2) and hence in sales too, if CircuitCo can cope with that.


The end isn't necessarily nigh.  It's a very good form factor.


Morgaine.

Re: [beagleboard] Re: Up, up and away and x15

[Gerald Coley]

Not sure on the single core board. Depends on how my therapy sessions go on
recovering from this one.

It would be possible to provide the same amount of memory, but it just 32b
one bus instead of two.
DSPs are half.
I believe the  PRUs are the same.
PCIe is only one lane instead of two.

Original plan was for a different a PMIC, but I don't know if I have the
guts to go through that again or not.

@Morgaine

Yes I can certainly crank out 25 or 30 more versions of the BBB with all
sort of combinations. If you drop HDMI you will save $3. Yes, that's right
$3. So we go from $55 to $52.

As long as someone agrees to buy 25,000 of each it would make sense to do.
Otherwise, the price goes up because we are building smaller quantities.

Gerald

Re: [beagleboard] Re: Up, up and away and x15

[William Hermans]

Didn't one user of the community make / build an SoC based on the BBB -
Last year ? Something with a DIMM like interface,
and minimal pin-outs. For like ~$35 ?

Anyway I'm having a hard time understanding how one could *try* and compare
a $9 garbage board that has a fraction of the
intrinsic value of the X15. Dual core A15 ( at 1.5Ghz ? ), multi PRUs /
DSPs, 2GB ddr, PCIe, and SATA. With a boat load of
other IO.

It's not that I would / could not find value in a $9 garbage board. It's
that feature wise the two do not even belong in the same solar
system - figuratively speaking. Passed that, I know I am not alone in the
world in understanding that while something may be
inexpensive cash wise, you usually end up paying for that mistake through
hard work trying to make such a thing work.

So in the context of being bitten once too many times - I guess I am dead.
As I'd rather work with something that is "proven" How does
that saying go ? Those who fail to learn from history are doomed to repeat
it ? Works for me . . .

 Gerald,

 So you mentioned a less expensive board with a single core processor.
 Is this the only difference, or do you think there will be other
 differences too ? Mostly I'm just wondering if that board would have the
 same amount of ddr, which I'm hoping it will.

 Can we also assume since that processor will be single core it would
 have hald the PRU's, and DSPs ? Or no ?

[beagleboard] Re: BBB 4xInput Audio Channel

[Walter Schilling]

You might take a look at 4 channel audio input cards / devices.  They are 
not cheap, but they can easily handle 4 inputs at the same time.  One such 
device 
is

 It would be possible to provide the same amount of memory, but it just
 32b one bus instead of two.
 DSPs are half.
 I believe the  PRUs are the same.
 PCIe is only one lane instead of two.

 Original plan was for a different a PMIC, but I don't know if I have
 the guts to go through that again or not.
