The boot button controls the SYS_BOOT2 pin on the processor which is
normally high (boot button not pressed) and loads u-boot from the eMMC.
Then, u-boot runs the scripts defined in it¹s environment. Use printenv to
see the env settings. If you are using minicom, for your console, press ctrl
a w to enable line wrap (or the equivalent command for putty, etc). enter
the printenv command and then scroll up to see the bootcmd which should look
something like this:
bootcmd=gpio set 53; i2c mw 0x24 1 0x3e; run findfdt; mmc dev 0; if mmc
rescan ; then echo micro SD card found;setenv mmcdev 0;else echo No micro SD
card found, setting mmcdev to 1;setenv mmcdev 1;fi;setenv bootpart
${mmcdev}:2;mmc dev ${mmcdev}; if mmc rescan; then gpio set 54; echo SD/MMC
found on device ${mmcdev};if run loadbootenv; then echo Loaded environment
from ${bootenv};run importbootenv;fi;if test -n $uenvcmd; then echo Running
uenvcmd ...;run uenvcmd;fi;gpio set 55; if run loaduimage; then gpio set 56;
run loadfdt;run mmcboot;fi;fi;
While this looks complicated, it really isn¹t. It starts of by turning on an
LED, runs a command findfdt which is defined as:
findfdt=if test $board_name = A335BONE; then setenv fdtfile am335x-bone.dtb;
fi; if test $board_name = A335BNLT; then setenv fdtfile
am335x-boneblack.dtb; fi; if test $board_name = A33515BB; then setenv
fdtfile am335x-evm.dtb; fi; if test $board_name = A335X_SK; then setenv
fdtfile am335x-evmsk.dtb; fi
Which just sets a variable ³fdtfile² to am335x-boneblack.dtb²
To prove this, enter these commands in u-boot:
run findfdt
echo $findfdt
Continuing with bootcmd, it test to see if the SDCard is installed (if mmc
rescan) and if it is, ³mmcdev² is set to ³0² (BTW, eMMC is mmcdev 1).
Reading further, the script then runs loadbootenv, which loads the uEnv.txt,
which it loads from SDCard if one is installed ($mmcdev = 0) or it loads
from eMMC if no SDCard is installed ($mmcdev = 1).
I¹ll leave your to read the remainder of the bootcmd script.
BTW, I believe this behavior is baked into u-boot and you have to change
u-boot source code to change this behavior. You can only modify u-boot
behavior after uEnv.txt is loaded.
Also, when you press the load button, u-boot is read from the SDCard. When
the load button isn¹t pressed, u-boot is read from the eMMC. So, to answer
your question, if you press the boot button, it will always boot from the
SDCard.
Regards,
John

Re: [beagleboard] Re: Custom built debian flasher Image not working
Hi Robert, Actually as it turned out, it was not a problem of power or keyboard. My initial analysis was wrong. It worked one time that got me thinking about this being keyboard fault, but it wasn't. I searched for the term emmc and flash in the filenames on my sd card and finally found the log file. The log file had a error rsync error chgrp failed: operation not permitted I checked the /tmp/boot and found that the owner of the files was root and group owner was plugdev. So I modified the emmc flasher script to stop the halevt service, and now its working fine. Thanks for replying. Please also reply to the locales issue in the other thread.

Re: [beagleboard] Re: Help Needed : Custom built debian image
Robert, My system while booting shows a debian boot splash. Then it shows a black screen for about 4 to 5 seconds before displaying the java program that I am running as my GUI. I am using startx command configured in /etc/rc.local to start the X environment and a /root/.xinitrc file to start my java program. Is there something I can do to reduce this 5 second of blank display time?

[beagleboard] Dude, where's my BeagleBone Black?
Just about to post this to http://beagleboard.org/blog, but it wouldn't hurt to get a bit of community feedback before pushing this out there Dude, where's my BeagleBone Black? I hear that question a LOT. No, we weren't sleeping, but sometimes it takes a minute for a plan to come together. And don't you love it when a plan comes together? Your BeagleBone Black is on the way and below are the whys and hows. Buying a BeagleBone Black back around October last year was easy---and then suddenly they were gone. Having a big launch and then slowing down to a more steady pace of production is what is normally expected. Demand was strong, but distributors were showing a small amount of stock and people were getting their boards on demand. Based on the status, distributors had requested CircuitCo (the Richardson, Texas based manufacturer of all official BeagleBoard.org boards) to provide boards at a certain pace, and production dropped from about 6,000 a week at launch to around 3,000 a week. Then came Radio Shack, filling their stores with Make's Getting Started with BeagleBone kit. Then the Christmas rush. Then the Georgia Tech massively open online course on control of mobile robots hosted on Coursera. We had a couple of small production boosts, but haven't been able to make any dent in the demand. Everyone is starting to find out what BeagleBone Black can do, using it in their classes, hobbies, prototypes---and products. When it comes to those people using a BeagleBone Black in an end product, well, the BeagleBoard.org terms and conditions clearly say we aren't responsible for the quality in those cases. Nevertheless, the quality speaks for itself and many people are choosing to simply drop them into things beyond just a few prototype units. In practice, we'll never know unless you try to return a bunch of boards at once for repairs. Our desire is that people using the boards in products work directly with a contract manufacturer or distributor to enable boards builds to be planned out in time and with terms and conditions that won't hurt BeagleBoard.org's ability to supply classrooms, hobbyists and professionals building prototypes. Still, if distributors show stock, I expect people building products to continue to chew up some of the board supply. While these people building products are certainly sucking up a lot of boards, it is clear they aren't the only source of the high demand. Some of our distribution partners, most notably Adafruit and Special Computing, put quantity limits of one board per customer on their orders to help keep supply going to individual makers. I took a look at Adafruit's website while they were showing some sock and observed board disappearing at the rate of about 2-3 PER MINUTE. One tweet from me and they were sold out again. This all leads to the obvious conclusion: we need more capacity. To accomplish this, we are taking a multiple prong approach of increasing capacity at CircuitCo as well as bringing on an additional manufacturer. These two prongs are summarized below. Prong #1 - Ramping up production at CircuitCo Ramping up production costs money. More test equipment is needed. Orders on various parts must be accelerated. Additional staff must be hired to run additional shifts. CircuitCo has been fantastic at taking the risk for us, but the margins for BeagleBone Black aren't the friendliest for them to take on these additional costs. At initial launch, it is a benefit for them to get exposed to more customers for their core business, complex circuit assembly and engineering services, but shipping more of the exact same board isn't going to give them a lot more exposure. We're really close to shifting the distribution shipped on our boards from Angstrom Distribution to Debian. Feedback from different people, especially Adafruit, tells us this will improve usability in the largest segments of our community. Angstrom Distribution is much more customizable and is very friendly to professional developers looking to tweak the most out of the system, but for many novices it introduces a barrier to learning. Debian is the basis for Ubuntu, includes ARM Cortex-A8 support in their mainline and is very familiar to a huge population of developers. It also takes a bit more space on the flash storage to provide the best user experience. To provide the best experience of using Debian on BeagleBone Black, we are connecting the switch-over to an increase in the on-board eMMC flash storage from 2GB to 4GB, leaving more free room in which you can work. The eMMC is faster and more reliable than micro-SD cards, so this is adding a lot of value---and a little bit of cost. These BeagleBone Blacks with Debian and 4GB eMMC will be called Rev C and they will likely cost a bit more at most distributors. This extra money is helping CircuitCo pay for the additional expense of the eMMC, but also to cover costs for ramping production to higher-than-ever rates. With the additional capacity

Good information and thank you Jason for sharing. I see there is also someone else producing miniature versions of the BBB, but . . . not my own thing. Personally, I would like to see other upgrades as well, but I voiced those last year, and from the response I received from Gerald seems to indicate that my own wishes are not inline with beagleboard.org's current roadmap. However, the minnowboard MAX is a perfect fit( even though using a different processsor architecture ). Personally, I never would have guessed last year at launch that the BBB would take off like this. But very pleased that it did.

Re: [beagleboard] HDMI to VGA, on boot the board displays its logo, but then ceases to display anything. Please Help
that seems to be exactly my problem too. unfortunately in austria it is impossible to get a (micro)hdmi to vga adapter with its own power supply. for some strange reason ebay, amazon and other stores won't ship them to austria. :/ is there any way around that? I'm powering my bbb with usb. i read somewhere that the bbb gets more power from a power supply unit than from usb. could that give the bbb enough power to also power the adapter? or what happened it i powered the bbb with a power supply unit and with usb at the same time? could that cause a short circuit or something or would it maybe work? I'm sure I could get a 5v power supply somewhere in austria but before i spend more money i'd like to know if it will make a difference. Am Samstag, 5.

Re: [beagleboard] Suggestion for change to Beaglebone PCB: USB header
I have to say that USB connection accesible from the side headers would be really nice feature. I aggre that you can loop a regular usb cable, but this way makes ot more robust and that just doesnt look good. Imagine someone buildibg a device basing on bbb. Everything could be connected to the cape and all a worker has to do is place the bbb on the cape.

Hello, I know this is an old post, but I was curious if you got an answer. I cannot find reference to WT being on the Agstrom repository. I have been trying to get it to work for several months now and I have not had any luck. It just won't build on the device (crashes at the final stages of the build) and cross-compiling doesn't seem to be working out for me either.

[beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
Has this image OpenGL/SGX support? I would need it to get QtQuick running on it. Last year I was not able to get the driver compiled but as far as I remember TI has published some kernel patches back then. Am Mittwoch, 5. März 2014 23:51:19 UTC+1 schrieb Jason Kridner: The latest BeagleBone Debian images are now posted at: http://beagleboard.org/latest-images/ If you've upgraded the firmware on your BeagleBone or BeagleBone Black in the past, the experience will be quite similar, but you might find the eMMC flashing times a bit faster (~15 minutes rather than ~45 minutes) due to less post-installation processing. Using the 2GB uSD card image also flashes a bit faster and can be resized to whatever your uSD card size is using some scripts under /opt/scripts/tools. Many, many thanks to Robert Nelson, Rob Rittman, Dave Anders, Cody Lacey, the Cloud9 IDE team and so many others in getting us this far. Please take the time to give a detailed look over this image and report any issues to the bug tracker on elinux.org: http://bugs.elinux.org/projects/debian-image-releases While plugged in over USB, you'll see the familiar BEAGLE_BONE drive with START.htm to tell you how to get the drivers configured if you haven't already done so: [image: Inline image 2] Clicking the link or visiting http://192.168.7.2, you'll see the familiar on-board served documentation: [image: Inline image 1] I've introduced a few bugs to the documentation ( http://github.com/beaglebone/bone101 and http://beagleboard.github.io/bone101), so expect to find a lot of issues there. Patches are welcome as are notes in the bug tracker to make sure I don't miss dotting any i's or crossing any t's. This is your chance to try to get some documentation into the system you'd like to see. I felt it was pretty safe to save the documentation as an in-beta item because it shouldn't impact functionality. One of the biggest new features you'll see is when you click on the Cloud9 IDE link: [image: Inline image 3] This is a pre-open-source-beta-only release of version 3 of their IDE. Down at the bottom of the Cloud9 IDE you'll see a new terminal window that runs a full 'tmux' session. You can open up a bunch of these and it makes logging into the board and executing command-line operations *super* simple. Cloud9 IDE version 3 now includes support for Python and the Adafruit_BBIO library is included in these Debian images. That means you can simply paste in your Python code and hit the run button, without any additional download. I checked this out myself by doing a quick LED blink using the Adafruit tutorial ( http://learn.adafruit.com/blinking-an-led-with-beaglebone-black/writing-a-program ): [image: Inline image 4] You should also note that the /var/lib/cloud9 directory now contains a git clone of that bone101 repo (http://github.com/beagleboard/bone101), so you can start using the Cloud9 IDE to edit the content live. What I recommend is creating your own fork of the repo and sending me pull requests of any changes you'd like to see. You can also edit C/C++ code in the Cloud9 IDE, but no 'builder' or 'runner' plug-ins are provided. You will, however, find the Userspace-Arduino (http://elinux.org/Userspace_Arduino) code in /opt/source/Userspace-Arduino. Here's a quick little exercise you can do to blink LED0: root@beaglebone# cd /opt/source/Userspace-Arduino/arduino-makefile/examples/Blink root@beaglebone# perl -i -pe 's/13/14/g' Blink.ino root@beaglebone# make root@beaglebone# ./build-userspace/Blink.elf For more advanced C/C++ developers, future releases should include https://github.com/jackmitch/libsoc. Those familiar with Linux will also note that the init system is 'systemd', which has been helpful in providing reasonable boot times. If you are looking for the journal, you can explore it using 'systemd-journalctl'. I use a Mac and despite the latest version of HoRNDIS fixing issues with Internet Connection Sharing, getting on the WIFI at home makes getting my BeagleBones on the network much easier, further making grabbing new packages with 'sudo apt-get install' much simpler. Drivers and firmware for many common USB WiFi dongles are included, so be sure to report any that you find missing. These latest images include the drivers for the popular UWN200 adapters provided by Logic Supply. To test it out myself, I uncommented and edited the wlan0 entry in /etc/network/interfaces (including replacing wlan0 with ra0), shutdown, plugged in the adapter and powered up the board again. I'm seeing the issue rt28xx_open return fail!, but I'm sure this is something we can fix in a few days and provide an updated image. I removed that adapter and plugged in an adapter I bought from Adafruit (and switched ra0 back to wlan0) and got the issue rtl8192cu:_rtl92cu_init_power_on():0-0 Failed to polling

cat $SLOTS
echo PUGGLE:00A1 $SLOTS
cat $SLOTS
I am using device tree compiler version: DTC 1.4.0-gf345d9e4
All the pins from the spi fragments work and I am able to generate an SPI
output using those pins. The problem is the single PRU pin I am trying to
initialize. It's pin P9.27 and I want to set it as an output in mode 5. But
this pin never gets initialized. I checked this by catting the pins file as
follows:
cat /sys/kernel/debug/pinctrl/44e10800.pinmux/pins | grep 9a4
and all I get out is:
pin 105 (44e109a4) 0027 pinctrl-single
To debug this, I tried changing the pin to P9.25 and even P8.46 but neither
of those pins were intialized either when I checked the pins file in
kernel/debug. I even tried running this on a different beaglebone black,
and still no luck.
Is there something fundamentally wrong in my device tree overlay? I'm a bit
confused as to why the pins for the spi0 and spi1 fragments get loaded but
not the pruss.
Thanks in advance!

I hear that question a LOT. No, we weren't sleeping, but sometimes it takes a minute for a plan to come together. And don't you love it when a plan comes together? Your BeagleBone Black is on the way and below are the whys and hows. Buying a BeagleBone Black back around October last year was easy---and then suddenly they were gone. Having a big launch and then slowing down to a more steady pace of production is what is normally expected. Demand was strong, but distributors were showing a small amount of stock and people were getting their boards on demand. Based on the status, distributors had requested CircuitCo (the Richardson, Texas based manufacturer of all official BeagleBoard.org boards) to provide boards at a certain pace, and production dropped from about 6,000 a week at launch to around 3,000 a week. Then came Radio Shack, filling their stores with Make's Getting Started with BeagleBone kit. Then the Christmas rush. Then the Georgia Tech massively open online course on control of mobile robots hosted on Coursera. We had a couple of small production boosts, but haven't been able to make any dent in the demand. Everyone is starting to find out what BeagleBone Black can do, using it in their classes, hobbies, prototypes---and products. When it comes to those people using a BeagleBone Black in an end product, well, the BeagleBoard.org terms and conditions clearly say we aren't responsible for the quality in those cases.

He's on the list here, saw the post last night. But already deleted it, and cannot remember his username.

I see there is also someone else producing miniature versions of the BBB, but . . . not my own thing. Who and what? Personally, I would like to see other upgrades as well, but I voiced those last year, and from the response I received from Gerald seems to indicate that my own wishes are not inline with beagleboard.org's current roadmap. However, the minnowboard MAX is a perfect fit( even though using a different processsor architecture ). Personally, I never would have guessed last year at launch that the BBB would take off like this. But very pleased that it did.

I hear that question a LOT. No, we weren't sleeping, but sometimes it takes a minute for a plan to come together. And don't you love it when a plan comes together? Your BeagleBone Black is on the way and below are the whys and hows. Buying a BeagleBone Black back around October last year was easy---and then suddenly they were gone. Having a big launch and then slowing down to a more steady pace of production is what is normally expected. Demand was strong, but distributors were showing a small amount of stock and people were getting their boards on demand. Based on the status, distributors had requested CircuitCo (the Richardson, Texas based manufacturer of all official BeagleBoard.org boards) to provide boards at a certain pace, and production dropped from about 6,000 a week at launch to around 3,000 a week. Then came Radio Shack, filling their stores with Make's Getting Started with BeagleBone kit. Then the Christmas rush. Then the Georgia Tech massively open online course on control of mobile robots hosted on Coursera. We had a couple of small production boosts, but haven't been able to make any dent in the demand. Everyone is starting to find out what BeagleBone Black can do, using it in their classes, hobbies, prototypes---and products. When it comes to those people using a BeagleBone Black in an end product, well, the BeagleBoard.org terms and conditions clearly say we aren't responsible for the quality in those cases.
