If you want to use P8.20, you need to disable the eMMC.  If you want to
use P8.45 you need to disable the HDMI output (and someone needs to
finish the missing cape-univ-hdmi).

Note that you can access almost as many PRU0 pins (11 out, 10 in)
without needing to disable either eMMC or HDMI.

 You should be able to just press the power button once briefly and it
 shutdown. Assuming the image you are running has it. The latest image does
 have it.

 After it powers down, then you can remove the power. We need to make
 sure the PMIC powers down all the rails to the processor  in order.

 Or you can enter “halt” on the console or terminal window and it will
 power off.

 John

[beagleboard] Re: Automotive Cape

[asancloud]

Just a quick update on the progress of the Cape.  Made a quick video to 
show the current status of bring-up. Demonstrating the automatic sleep and 
wake functionality using the vehicle ignition signal, vital really for 
saving power.

Have a look at the Cape Demo 

More will be posted soon, now that we have got over the initial issues 
bring-up should be fairly quick.

[beagleboard] Slow boot sequence caused by Cape Manager and Device Tree Overlaying

[becker . vosloo]

*Background Information:*
I am using a standard Beaglebone Black with the latest version of Angstrom 
(2013.09.04) loaded.
I developed software to that uses eqep2 on the Beaglebone Black and it 
works well, I get the correct results from the quadrature counter.  

*Problem Description:*
A problem is that the related Device Tree Overlay in conjunction with the 
Cape Manager cause my BBB boot-up time to extend beyond 60 seconds, and it
seems to be related to the cape manager trying to load cape firmware as the 
snippet from the boot-up sequence, shown below, suggests.  
However, in essence I do not have an actual cape, I merely assign the eqep2 
pins to P8.39, 40, 41 and 42 using a Device Tree Overlay and then access 
the eqep2 registers 
using mmap in my software, and as mentioned earlier it works as expected.


[0.480195] pinctrl-single 44e10800.pinmux: pin-21 (gpio-leds.8) status

[beagleboard] Beaglebone book authoring opportunity

[richardhpackt]

Hi all,

Some of you may be aware that about a year ago, one of my colleagues at 
Packt Publishing posted a request for potential authors to write for us on 
Beaglebone. We received some excellent responses and two of these led to 
authors writing titles for us, which have since been published and have 
been critically and commercially successful:
http://www.amazon.com/BeagleBone-Robotic-Projects-Richard-Grimmett/dp/1783559322/
http://www.amazon.com/Building-Home-Security-System-BeagleBone/dp/1783559608/

We are looking to follow up on this success with another title on 'Building 
an Internet of Things with BeagleBone'. We're open to suggestions on 
potential projects that fit this theme. Like our other titles, it'll be 
practically focused and is a great fit for a potential author/authors who 
want to share their knowledge and passion for tinkering, making and 
building. 

If this sounds like you, we'd love to hear from you. I am the editor for 
this project, so please mail me at richa...@packtpub.com with a background 
of your interests and skills, along with any initial project ideas you may 
have. We can then discuss this together, where I can provide you with more 
details, along with working with you to develop ideas. Perks include an 
advance payment against royalties, and a much-higher-than-industry-average 
royalty percentage as standard.

Thanks

Richard Harvey

[beagleboard] Video Frame Grabbing

[Alastair Gilmore]

Hi,
   Could someone point me in the right direction please. I'm trying to 
use Derek Molloys boneCV files on the BBB. When I run the build script it 
throws errors, which seem to be linked to there being no libv4l2.pc 
library. V4L2 is installed but a "Find libv4l2.pc" finds nothing. It also 
refers to setting pkg_config_path to point to this library.

Thanks

Alastair

At any rate why not a crossover cable?  or through your home router?

Well, if the "debian" image here:
http://beagleboard.org/latest-images

Doesn't create a usb-eth link on your host system on bootup. There is
either a problem with the usb cable or your host system.

If you don't have an actual cape, you must be telling capemgr to load
the overlay for you.  If you don't want capemgr to load the overlay,
don't tell it to do so.

> Is there a different way to speed up the boot time?

One way is to avoid the capemgr and merge your device tree changes into
the root device tree file loaded by u-boot.

There are also many other ways to improve boot time which are unrelated
to device tree overlays.  Google a bit and you'll find lots of info.

[beagleboard] BBB, BB-View and I2C

[Colin Bester]

I am using  a beagle bone with angstrom os and bb-view 4.3 inch LCD and am 
wanting to use i2c as well.

I see that the bb-view uses pins P9-17/18 which are i2c1 but that is also 
uses P-20 as GPIO for LED1 which seems rather silly to blow a I2C port for 
simple digital output.

Question is can I still somehow use I2C 2 (Pins P9_19/20) as I2C? Can I 
somehow disable LCD's use of this pin?

[beagleboard] Different pictures on different LED matrices with one BeagleBone Black

[John McClaire]

Hello ya'll,

Does anyone know where I can find help with displaying images on multiple 
LED panels? I don't want the same image to stretch across all the LED 
matrices. Is this possible? If not, my thought was to make the animation's 
all on one file and just space it out so they are on separate panels. Does 
this make sense?

Thanks for any help or advice!

Did you "modify" any GPL software on the system?

We did at beagleboard.org, all those *.deb's we changed also have
source available on debian.beagleboard.org (apt-get source xyz) will
retrieve files.

Yes it includes the "non-free" repo enabled by default.  Which
therefore means "non-free" firmware is installed. I'm sorry, but I'd
rather have our userbase be able to use their wifi adapters.

(atmel-firmware firmware-ralink firmware-realtek libertas-firmware
zd1211-firmware)

BTW:

If this switch from "Angstrom" to "Debian" is too much for you.  You
can always contract with someone to give you Angstrom. (it won't be
me)

[beagleboard] [PATCH] linux-mainline: Enable CONFIG_FHANDLE on BeagleBone

[samoht . yrag]

From: Gary Thomas 

This kernel setting is required when using systemd >= 210.  Without
it, no serial login is possible.

Tested on BeagleBoneBlack with serial adapter.

[beagleboard] WL18xx with BeagleboneBlack

[Ronald Garay]

I've been working on the following link:

http://processors.wiki.ti.com/index.php/Using_the_WL18xx_Cape_with_BeagleBone_Black

I was able to go through the process with some adjustments needed (a 
download link is not up to date), except for 1 step. Under *Updating the 
File System*, the last step asks to copy *3.8.13-dirty* folder from rootfs 
but I do not have that folder. I do have  *3.8.13-00726-gda51976-dirty *(with 
some changes on the gda...). I'm wondering if I missed something or if 
there is an issue with the instructions? 

Also, I seem to not be able to SSH with the board when it has the Angstrom 
kernel. Is there anything I have to do to get that working? I'm using a Mac 
with Mavericks. Also have a PC with windows 7 that is also running an 
Ubuntu VM.

Thank you.

[beagleboard] DRVVBUS, devmem2 and resetting USB devices

[Jason Kridner]

Anyone else feel like devmem2 should likely be in the feeds? I know it
is hacky, but it is nice for when you are hacking.

With that general question out of the way and not trying to play
expert here, but to raise a couple of questions when working with the
3.8.x kernel and Debian... my hope is that someone can fill in the
details quickly before I spend some time probing. Sorry if this is
noise to you.

I know hotplug issues have been a concern for a long time now:
https://groups.google.com/forum/?fromgroups#!searchin/beagleboard/lsusb$20hotplug/beagleboard/nuyyVDhU6bw/XpaN_3jVqmUJ

I'm seeing if I can't get them run-to-ground, but I'd like to also
check on people's experience with resetting devices and figure out the
best way to control that. I haven't seen much discussion on that here,
but it was covered on the TI e2e forum:
http://e2e.ti.com/support/arm/sitara_arm/f/791/t/270060.aspx

I've seen that the ioctl to reset a USB device seems to work fine.
Here's a link to code for that:
http://askubuntu.com/questions/645/how-do-you-reset-a-usb-device-from-the-command-line

 I haven't taken the time to wire-up probes or dig through the code to
see if this is just doing a setting of DP/DM low for the reset
duration or performing the DRVVBUS take-down. Either way, it seems to
be resetting my USB devices just fine. In exploring hotplug issues, do
I need to be looking at the behavior of DRVVBUS as well and is anyone
very familiar with the right way it should be handled in Linux (ie.,
not the devmem2 way)?

+1 for inclusion "out of the box", but I'd tweak it slightly and make a
peek and poke routine.  But devmem2 as-is would be *WAY* better than
nothing!

...I haven't really messed with the other issues, but getting USB
hot-plug working better (or at all) would be good.  I don't typically
try to hot-plug things, but it is a hassle and there are some use cases
(with memory sticks to transfer data, for instance) which just don't
work w/o proper hot-plug.  I copy data around with wired Ethernet, but
not everyone has that setup and no hot-plug makes sneaker-net even more
painful!  :)

[beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[Rick Reynolds]

Hi All, This is my first post on the group. Hope I'm in the correct place. 
Hate to sound like such a noob but, that's what I am. 

I am working with a Beaglebone Black revision B, 7" HDMI display and USB 
eGalax based touch screen. We are currently have 5 revision C boards on 
order.

I am booting from a 2gb sd using the 3.14.4-bone4.1 kernel and 
debian-7.5-minimal-armhf-2014-05-07 rootfs. I did a cross build on a Wheezy 
VM using the info from 
http://eewiki.net/pages/viewpage.action?pageId=13599118.
I have installed LXDE and everything is working really well. 

I have one small touchscreen issue however. It works correctly except that 
I cannot get the pointer to the edge of the screen. Not close enough to 
activate the panel menus and such.
>From what I've read I believe the xinput-calibrator utility would help 
solve this issue. But, I can't find the package with sudo apt-get install 
xinput-calibrator.

I have downloaded the source for version 0.7.5 from freedesktop.org and I'm 
trying to cross build it. No luck so far... I know that this utility is 
installed by default on the latest Debian/LXDE images from Beagleboard.org 
but i really want to be able to configure and build all of this myself. 

What is the best method for providing the ./configure output and config.log 
content here? The tail of the ./configure output is below but I know it 
would probably be helpful to have the entire output and the config.log 
content. 

./configure output

Current price point? This board will not be a $55 board. This board is a
BeagleBoard, not a BeagleBone. This board is in a different class than the
BeagleBone.

It's easier to just build in on the bone.. (make sure libxi-dev is
installed)

git clone https://github.com/tias/xinput_calibrator
cd xinput_calibrator
./autogen.sh --with-gui=x11
make
make install
make distclean

Hello Alberto,

you can use libpruio  to check the 
logic level of any GPIO in an easy and fast manner. In that case you don't 
need any device tree overlay during development phase. (But create one when 
you're finished, just to lock the used pins.)

[beagleboard] Supply required 5V/2A over micro USB

[andrewjamest1993]

Hey guys, quick question. I have a portable tablet charger capable of 
supplying 5V/2A over USB. Can I use this to power the board? Or is the 
micro-USB limited in what I can supply to it? Will I be able to power both 
the board itself and a USB WiFi dongle safely?

Re: [beagleboard] Supply required 5V/2A over micro USB

[Gerald Coley]

Yes, but understand, you will only get 500ma out of it before the PMIC
shuts down depending on where the SW is currently set.I actually do not
know on the new image. Best case it 800mA.

Either way, you will not get 2A.

I still have it do the "i2c mw 0x24 1 0x3e;" in u-boot during bootup..
So whatever that sets up the PMIC for.

If I¹m reading the data sheet correctly,

IAC current limit 2,500mA
IUSB current limit 1,300mA

0x3F would make iUSB current limit 1,800mA

I think that is the 800mA setting in the PMIC over current circuitry.

Yes. 1.3A is what I meant. So, 1.3A may still be pushing it.

Re: [beagleboard] Re: PRU Pin Mux

[foreverska]

I thought we disabled the HDM in the first place... it's disabled in my 
uENv.

"Note that you can access almost as many PRU0 pins (11 out, 10 in) 
without needing to disable either eMMC or HDMI."

Unfortuantely I need both processors.  If I could even find two inputs on 
PRU1 I would just move that core over to it and make PRU0 the talkative one.

What's the deal with STC/LFC?  Its in the AM18xx instruction list but they 
talk about depreciating it.  If one core could write to the other's R30 
it's a wasted cycle but if I could free up the LCD pins and have all of the 
other PRU's excess pins I could definitely use that.

Yes, recall I said:

Feel free to send a pull request adding cape-uinv-hdmi!  :)

[beagleboard] Re: WL18xx with BeagleboneBlack

[Ronald Garay]

Just an update, I went through the steps again and had the same results as 
far as files created goes. I don't see any of the LEDs on the cape turn on. 
Will play with it to see how it behaves.

Thanks for your help, and all your hard work, Robert. I have used your 
documentation extensively.

When I execute "./autogen.sh --with-gui=x11" either directly on the bone, 
from a an LXTerminal session, or over ssh I get the same end result. it's 
basically the same thing I saw when trying to cross build.

[beagleboard] Enabling TIMER4 output

[Rob Dekelbaum]

Hi,

 I'm trying to get things set up to use TIMER4 (or 5, 6, or 7) to provide 
an external clock source to another component and I'm having some trouble. 
For now I'm happy with just getting the standard 24khz clock, though I may 
want to be able to modify the frequency in the future.

I'm using the Yocto Project (Dora) to build my images and the straight TI 
kernels from the meta-ti layer (linux-ti-staging_3.12) with a static 
devicetree. I've customized my devicetree enough that I'm somewhat 
comfortable with devicetree configs, but I know I'm a long way from having 
real devicetree-fu. That said, I've added the following in an attempt to 
get TIMER4 to come up:

In the am33xx_pinmux section:

timer4_pins: pinmux_timer4_pins {
  pinctrl-single,pins = <
0x90 0x12  /* gpmc_advn_ale as TIMER4, OUTPUT_PULLUP | MODE2 */
  >;
};

And further down (note: I'm not certain this is necessary or correct, but 
it was a shot in the dark):

&timer4_fck {
pinctrl-names = "default";
pinctrl-0 = <&timer4_pins>;
status = "okay";
};

I sadly don't have a scope to verify clock on the TIMER4 pin, but my guess 
is that something's not qorking right from the following reported in 
/sys/kernel/debug/clk/clk_summary (note: I clipped bit after the relevant 
part):

root@beaglebone:/sys/kernel/debug/clk# more clk_summary 
   clockenable_cnt  prepare_cnt  rate
-
 tclkin_ck  0   01200  
 virt_2600_ck   0   02600  
 virt_2500_ck   0   02500  
 virt_2400_ck   1   12400  
sys_clkin_ck9   23   2400  
   dpll_mpu_ck  1   13 
  dpll_mpu_m2_ck4   43 
   timer6_fck   0   12400  
   timer3_fck   0   12400  
   dbg_sysclk_ck0   12400  
   timer7_fck   0   12400  
   timer5_fck   0   12400  
   timer4_fck   0   12400  
   timer2_fck   1   12400  
   timer1_fck   1   12400  

I also haven't seen the device that needs the clocking initialize properly 
yet, so that's another tipoff.

Maybe related, I'm also seeing the following in the dmesg:

[0.132509] platform mpu.1: FIXME: clock-name 'fck' DOES NOT exist in dt!

Any help or pointers would be appreciated. I've tried looking at section 20 
in the AM335x TRM and I get the feeling there's just a register setting or 
two that need to be done, but I'm just beginning to learn the hardware end 
of the universe after many years as a UN*X guy, so I got a bit lost in 
trying to figure out how to do it.

Thanks,

-d

Re: [beagleboard] Re: PRU Pin Mux

[foreverska]

Oh... I'm barely getting by with what I'm doing much less figuring that 
out.  I really really really would love it done or any sort of work around 
that would allow me to assign those pins to the PRU config-pin or not. 
 This project is very cramped without those pins.  Doable on entry level 
stages but very cramped.
