I'm newbie on Beaglebone black and audio cape, could anyone kindly give me the idea how to install audio cape rev B board on kernel 3.18. Since on kernel 3.8, there is cape manager, while it has been removed since 3.13. For the moment, I really have no idea how to install the board on new kernel. Thank you in advance.
The cape manager is no longer needed. Simply write the name of your device overlay (eg, BB-BONE-AUDI-02) to
/sys/devices/bone*/slots
to add the device.
For example,
# echo BB-BONE-AUDI-02 > /sys/devices/bone*/slots
Then cat that file to make sure your device is listed. Make sure HDMI has been disabled as well.

I got some brand new banana Pi's,
these are the "Banana Pi-M2" and the "Banana Pi-M3"
I was trying to install Debian on both of them, but I couldn't get it to work.
I was exactly following this tutorial here (Windows):
http://wiki.lemaker.org/BananaPro/Pi:SD_card_installation
to save Debian on the SD Card.
The Problem is always the same. When pressing the power Button on the "M3", or plugging in the "M2", only the red LED goes on and nothing happens.
The LED for the LAN port stays off, so it comes close that the Pi is not booting up.
The power supply I am using produces 5V and 2100mA which should fit the conditions for the Banana Pi.
The distros I then tried to install were for example Bananian which I got from here:
https://www.bananian.org/download
And several distros like Debian from here:
http://www.banana-pi.org/m3-download.html
http://www.banana-pi.org/m2-download.html
I tested it using 2 different SD Cards, and also only using a USB Stick.
everything was producing the same error.
Is there something I missed?
Thanks in advance.
It sounds like an underpowering situation.
If you have a barrel jack instead of micro usb use the barrel jack.
The pre-production samples of this board had the usual 4.0/1.7mm barrel jack for DC-IN BPi M2/M2+ also use. This has been replaced by a Micro USB jack on the first production batch in Dec 2015 leading to the usual sorts of problems banana-pi.org forums are full of (see also next paragraph for some reasons). Starting in May 2016 Micro USB has been replaced by the 4.0/1.7mm barrel jack again so powering is possible more reliable now. The Micro USB receptacle on the longer board side is USB OTG, also connected to the board's PMIC and while looking like an alternative way to power the board that's not recommended unless you love underpowering situations, reboot loops and the like.
I had the same problems at one point, like #Hagen said, it could be under powered, make sure you have a 5V, 2A rated power supply. The other cause of the red led and no boot is the lack of a micro SD card. Try pushing it in a bit further though not with much force and hit reboot. if you get 3 leds, it works!
This Banana PI M3 device starts up and works normally when power supply connector (4mm/1,7mm) and a micro USB connect put to device of Banana same time from same 5V power supply. I think in the device may have something grounding problems.
I have a goodix chip for the touchscreen on my tablet PC and even though I compiled the latest kernel module for it, things are not working.
I am using exactly this kernel version with the patched driver:
https://github.com/NimbleX/kernel
For starters, the picture of the said chip is the following:
The DSDT tables contain information regarding the touchscreen.
From what I understand the touchscreen is connected via an I2C serial interface but lshw shows that *-serial is UNCLAIMED.
Nevertheless I can see that the i2c_i801 module for the SMBus controller is loaded.
With the help of Aleksei I was able to determine that the toucscreen is connected to i2c-1 buss and that the controller must use 0x14 or 0x5d address.
Unfortunatelly, i2cdetect doesn't find anything, as it can be seen here.
I created a lengthy gist with the output of the following:
dmesg
DSDT.dsl
lshw
lspci
lsusb
/proc/bus/input/devices
xinput
I know that some of these are redundant and that others are useless but nevertheless it's better to have where to search than to miss something out.
I measured with a multimeter and the chip is powered both when running Windows and Linux so this rules out that I need to somehow tell Linux to power this thing out.
So, what do do next in order to debug this thing?
Hi can you check where pin 5,6 are connected specifically 6 which is reset ic so if that may be reseting the ic. just a posiblity.
I have been working for a few days trying to get the UART1 port to work on a bbb. I flashed the prebuilt kernel from the elinux wiki (http://www.elinux.org/BeagleBoardUbuntu#Flasher), and the UART1 appears in the /dev folder (as /dev/ttyO1, with a capital "o" not a zero), but when I write to it, nothing comes out of the pins. I can use UART0 (on a separate little serial header, but not the one I need) without any trouble.
I see a lot of tutorials for enabling UART1 that deal with a folder called /sys/devices/bone_capemgr.* but I don't have one. I think it is because I have a newer kernel, and nearly all of those tutorials are exclusively for older kernels (<=3.8).
I read that the current 3.13 images from Robert C Nelson don't have a cape-manager (https://groups.google.com/forum/m/#!topic/beagleboard/ND3_w7_dn8Q), and you can use the "really simple cape manager" (https://github.com/RobertCNelson/rscm), but the build.sh script doesn't work on my 3.14 kernel. I tried to change a path in the script to fix it and now that bbb won't boot.
I also tried the beaglebone-universal-io script (
https://github.com/cdsteinkuehler/beaglebone-universal-io) but when I query the relevant pin:
sudo ./config-pin -q P8_26
I get the error:
P8_26 pinmux file not found!
Please verify your device tree file
Am I missing something really simple here?
I am a newbie in Beaglebone Black, I install Ubuntu on my Beaglebone Black which works fine, Now I am trying to install Angstrom on Beaglebone Black, for this I first of all download image of Angstrom "Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.08.21.img" , then extract it using "7Zip" , after that I use "Win32 Disk Imager" to copy it into a 16 GB SD card.Now insert my SD card in Beaglebone Black. Then I press boot button and after that I provide power supply using 5v and 1 Amp adapter. After making sure that all four LED's are glowing , I release boot button.
Now the problem is the installation should be completed in around 45 minute and all four LED's should become stable , but in my case LED's keeps blinking. I check it more than four times for around more than one and a half hour and after that I take out the power supply and check Beaglebone Board on my desktop monitor, surprisingly Ubuntu is Still there.So, please tell where is the problem.
Use this file "BBB-eMMC-flasher-2013.09.04" under BeagleBone Black (eMMC flasher) for flashing to eMMC
I had also installed Angstrom on BeagleBoard Black.
You should follow derek molloy tutorial. Here is the link to tutorial
It should boot up in 10 seconds. It will not take 45 minute to boot up if properly installed.
After having set-up and customized my "master" BeagleBone Black (BBB) with applications etc. on the on-board eMMC, I want to duplicate it on other BBB boards.
What is the best way to duplicate the BBB?
My understanding of options:
SD-Card: Programming each board by inserting a prepared SD card containing an image and pressing the "boot" switch while powering up.
How should I prepare that .img file or the SD card from my master BBB?
The image should copy to the on-board eMMC, so that the SD-card can be removed afterwards.
USB: Programming by connecting the board over USB to a (Win7) PC.
Is it possible to write the full on-board eMMC from the PC?
With which app to do the writing?
How to prepare the image which will be written, starting from the master BBB?
Ethernet: Programming over LAN after boot-up with default angstrom distro.
Is it even possible over LAN?
How to do the writing?
How to prepare the image which will be written, starting from the master BBB?
Which is possible/best?
Edit: My current solution is to flash with a standard image (from the BeagleBoe website) and then have a script do all modifications as expected. This includes disabling many services I don't need, installing applications and configuring stuff etc.
If there is an easier way for making a SD card with a full image on it, I'm still interested.
As noted at the bottom of the eLinux article, there is a much easier way if you are running the Debian distribution:
Boot master BBB with no SD card in
Insert SD card
Log in (e.g. with serial terminal, SSH etc.) and run sudo /opt/scripts/tools/eMMC/beaglebone-black-make-microSD-flasher-from-eMMC.sh. LEDs will flash in sequence whilst SD card is being written.
When the LEDs stop and the script terminates, remove the SD card.
Insert SD card into new BBB then power on.
eMMC will be flashed; LEDs on new BBB will flash in sequence until complete.
For anyone else that needs this, the best answer I've found to this is to do the following:
First setup your master Beaglebone Black the way you want it.
Backup the eMMC
FAT format a 4GB or larger SD card (must be a MBR/bootable formatted microSD card)
Download beagleboneblack-save-emmc.zip and extract the contents onto your SD card
Note: this is an image from Jason Krinder at his github https://github.com/jadonk/buildroot using the save-emmc-0.0.1 tag
Put the card into your powered off Beaglebone Black
Power on your Beaglebone Black while holding the S2 Button
The USR0 led will blink for about 10 minutes, when it's steady on you have an SD card with a copy of your eMMC in a .img file
Use the eMMC to flash a new Beaglebone Black
On the SD card edit autorun.sh
#!/bin/sh
echo timer > /sys/class/leds/beaglebone\:green\:usr0/trigger
dd if=/mnt/<image-file>.img of=/dev/mmcblk1 bs=10M
sync
echo default-on > /sys/class/leds/beaglebone\:green\:usr0/trigger
where <image-file> is the image file you got after copying backing up your eMMC
Insert the card into your powered off Beaglebone Black
Power on your Beaglebone Black while holding the S2 Button
The Beaglebone Black should go into rebuilding mode and within about 20 minutes you'll have a newly flashed Beaglebone Black (when all 4 USR LEDs are solid) with a copy of your original

I have the same need and am using dd and nc (NetCat) to save directly on my desktop without having to use an intermediary SD Card. You can do this over the USB connection, or ethernet connection, by changing the IP address in the steps below.
After setting up your BBB with the applications you want, the basic steps are:
On the desktop, run this command in a terminal:
nc -l 19000|bzip2 -d|dd bs=16M of=BBB.img
On the BeagleBone Black, run this command in a terminal (you can SSH into it, or do it directly from the BBB):
dd bs=16M if=/dev/mmcblk0|bzip2 -c|nc 192.168.7.1 19000
The 192.168.7.1 address is for the USB connection. (BBB is 192.168.7.2) If you're doing this over an ethernet connection, you should use your desktop's IP address.
This is taken from instructions here.
Finally, follow any method to install onto the next BBB. Here's an example of how to flash the emmc.
Copying your emmc Image back to a SD card is a bit tricky, since it will need to be formated in a certain way to get it to mount. Here are some tips to get that working: http://dev.gentoo.org/~armin76/arm/beagleboneblack/install_emmc.xml#expand
What might be easier is using an USB thumb drive, or USB SD card reader. Note, currently there are some issues hot-plugging USB devices, so boot with it plugged in.
You can copy your entire FS to the USB drive, then compress it. Create a new bootable linux sd image, and put your compressed FS on there and use one of the scripts Ottavio linked to to copy over the compressed image. you can make a systemd service to launch the script on startup.
We have noticed that on Beaglebones with the Jan 23rd 2015 release of Debian, the only way to successfully copy the image from SD is not to hold the boot button down when powering up.
