Installing tools from the Ubuntu repos seems no longer possible. I get the following error message on "apt update"

W: Failed to fetch http://ports.ubuntu.com/ubuntu-ports/dists/vivid-updates/main/binary-armhf/Packages 404 Not Found [IP: 91.189.88.150 80]

Is there an updated Parabuntu? Or is it possible to upgrade the image myself?

It seems that vivid version of Ubuntu is no longer supported. If the parabuntu maintainer does not prepare new version it will stay like that. I have made dirty hack by edit /etc/sources.list file exchanging "vivid" to "xenial". At least for my case it works and I could install few packages I need (e.g. mc, gnuplot). There were no essential errors during update and installation. Maybe that helps you as well?

I cant even get into the ssh for my board.

login as: parallella parallella@192.168.56.1's password: Access denied parallella@192.168.56.1's password: (LOCAL ETH DIRECTLY PLUGGED INTO LAPTOP ONLY)

can you connect using serial? Anyway, it is almost impossible to not be able to login into standard distribution using standard account and password... check whether you really boot the right image and connect to the right network node, however looking to ssh output you did well.... You can also try to mount the sd card in your laptop directly and remove parallella password from /etc/shadow and then try to log in again.

I have done the upgrade from "vivid" to "xenial" and had my system working fine. Then I have upgraded to "bionic" two days ago and it worked fine as well. No issues found during the process. Next step should be to update the kernel...

Comment out all existing release links and add below in the file /etc/apt/sources.list

After almost four months of Parallella working on Bionic, I can confirm that the upgrade path worked perfectly... what @agent001 mentioned in the previous post (about using the "old-releases.ubuntu.com") is important as it will allow the update from an unsupported version to another unsupported one.

tslpre, would you be willing to provide guidance regarding how you upgraded the Parallella to bionic? I would like to do that myself. Do you have the ability to still program for the Epiphany?

@njpacoma being the current version (Vivid) not supported anymore, you need to update the sources.list manually so you can update to xenial (that is a LTS) and then from there you can update to Bionic (that is the following LTS). Have a look at the answer at: https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release

That's basically what you should do :)

Let me know if you need more details.

Thanks, tslpre, I managed to upgrade to Bionic. There were a bunch of pitfalls along the way and I am not sure I could easily reproduce the steps without working through the process again and working out how I got around those pitfalls. I tried a couple of the parallella examples and they seem to still work. Appreciate the pointer.

I upgraded to Bionic after

1) partition size increase using https://linuxconfig.org/how-to-resize-ext4-root-partition-live-without-umount 2) From vivid => wily, wily=> xenial following this https://linuxconfig.org/how-to-upgrade-to-ubuntu-18-04-lts-bionic-beaver#h9-how-to-upgrade-ubuntu-the-debian-way 3) xenial => bionic using standard do-release-upgrade

The source list produced by https://repogen.simplylinux.ch/generate.php was useful. And I had to manually update the vivid source list a) sudo sed -i 's/vivid/xenial/g' /etc/apt/sources.list b) for i in find /etc/apt/sources.list.d/ -type f | xargs grep vivid -l;do sudo sed -i 's/vivid/xenial/g' $i;done

Is there an image file that I can download?

I'm far from a linux guru, this is way out of my pay grade.

boneoh, do you have the desktop or the server? do you have more than one?

I am not sure that the kernel after the upgrade is the latest Ubuntu kernel or if it has been kept back because it was a custom build. The uname command shows

Linux parallella-1 4.6.0+ #1 SMP PREEMPT Wed Dec 7 13:27:40 CET 2016 armv7l armv7l armv7l GNU/Linux

This is what is in the /etc/os-release file

If you are looking for the latest and greatest kernel, this won't give it to you. I upgraded because some of the software I wanted to install was no longer available.

Hi, Ted!

Thank you very much for taking the time to help me.

Here is the uname output:

Linux parallella 4.6.0+ #1 SMP PREEMPT Wed Dec 7 13:27:40 CET 2016 armv7l armv7l armv7l GNU/Linux

Here NAME="Ubuntu" VERSION="15.04 (Vivid Vervet)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 15.04" VERSION_ID="15.04" HOME_URL="http://www.ubuntu.com/" SUPPORT_URL="http://help.ubuntu.com/" BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"

So it looks like my output matches your examples.

Please forgive my ignorance. I’m a computer guy, but not much exposure to linux. Mostly as a user for Raspberry Pi. I’m looking at Parallella as a possible fit for an embedded processor. I’d like to use the Parallella for video image processing.

If you have the time, would you mind answering a couple of questions?

Sudo apt-get update, upgrade, etc. seem to fail because of being so out of date. Is the correct approach to install the latest parabuntu? I’m clueless as to what to try next.

I am guessing that the Parallella requires a customized version of linux in order to support the hardware?

I would really like to get this up and going, it seems like such an awesome device. I ran a bunch of the examples, this seems like a good solution for my needs.

Thanks again for your help!

Regards,

Pete

@boneoh - what @njpacoma said above is correct - when you update to a new Ubuntu version, the old kernel will stay there. This doesn't mean that it won't work, but if you need to do something that requires support for a specific hardware or functionality, you will need a newer one. As I'm playing with docker, I have compiled a new one.

As commented on my post above, compiling the kernel was the last missing piece to have a fully updated ubuntu.

Let me share how I did it, step by step: `mkdir /home/yourprofile/kernel # create a folder somewhere to store the kernel to be compiled

cd kernel git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git # download the kernel sources

cd linux-stable-rc git tag -l | less #this command is optional - it will allow you to see with versions you can choose

git checkout -b stable v4.9.99 #I'm using the version 4.9.99 right now

now you should customize the kernel config - I will attach here the version I'm using - just decompress it in the same folder you are currently: /home/yourprofile/kernel/linux-stable-rc

kernel_config.tar.gz

make -j 4 LOADADDR=0x8000 make -j 4 LOADADDR=0x8000 uImage make -j 4 LOADADDR=0x8000 zynq-parallella-headless-noelink.dtb make CFLAGS_MODULE=-fno-pic -j 4 LOADADDR=0x8000 modules export MODULES_INSTALL_DIR=$PWD/modules export HEADERS_INSTALL_DIR=$PWD/headers make -j 4 LOADADDR=0x8000 INSTALL_MOD_PATH=$MODULES_INSTALL_DIR modules_install make -j 4 LOADADDR=0x8000 INSTALL_HDR_PATH=$HEADERS_INSTALL_DIR headers_install

sudo mount /dev/mmcblk0p1 /mnt #mounting the partition with the current kernel cd /mnt sudo cp uImage uImage.old #create a copy of the original kernel, just in case sudo cp /home/yourprofile/kernel/linux-stable-rc/arch/arm/boot/uImage . #copying the new kernel image cd /lib/modules/ sudo cp -a /home/yourprofile/kernel/linux-stable-rc/modules/lib/modules/4.9.99/ .`

Then you can reboot and you should have the new kernel...

@boneoh, please send your email address to tswoyer at gmail.com and I will send you a link to a downloadable image.

@njpacoma Thank you so much for the image, Ted! I was able to setting up a static IP and a few other things to get going. I've backed up the image so I can experiment!

@tslpre I am in the process of following your recipe above! Thanks for posting that.

After that, I hope to run all of the examples.

@tslpre I've done the git ok, and downloaded kernel config. I've never built the kernel before, sounds a bit intimidating!

Out of curiosity, I looked at the config file, I didn't realize that there are so many options!

A little background, I am working with parallella at home, but there may be use for this in my work environment. Think of parallella as an embedded processor for medical imaging. So this would need HDMI, Bluetooth, and Wifi (using USB adapters).

So before I build the kernel, I'd like to know how to check the config to make sure the appropriate settings are in there. Is there somewhere I can lookup these?

I was surprised to see config options for Health related stuff like temperature, humidity, heart rate, etc. I'd like to learn more about them as well.

I'm also interested in the Kinect demo, it looks fun. I think we could use this to create maps of rooms to help with object tracking.

Thanks again for the help.

Mr. Google has found this for me https://help.ubuntu.com/lts/installation-guide/s390x/ch08s06.html

Looks like I may be missing a file or ?

parallella@master_cylinder:~/kernel/linux-stable-rc$ make -j 4 LOADADDR=0x8000 zynq-parallella-headless-noelink.dtb make[1]: No rule to make target 'arch/arm/boot/dts/zynq-parallella-headless-noelink.dtb'. Stop. arch/arm/Makefile:336: recipe for target 'zynq-parallella-headless-noelink.dtb' failed make: [zynq-parallella-headless-noelink.dtb] Error 2**

Any guidance is greatly appreciated! Thanks,

Pete

@boneoh the file .dtb is a "Device Tree file - if you mount /dev/mmcblk0p1 to a temporary folder (for example: sudo mount /dev/mmcblk0p1 /mnt) you will see that you will find a file called devicetree.dtb - that is the standard one - please use that one.

The one I was referring to (zynq-parallella-headless-noelink.dtb) it's a custom one - my bad, I should have mentioned the standard one in my post.

With that change in mind, you should be able to build everything properly :)

@tslpre Thanks again for your help! The device tree change got me passed the problem. I am now up and running with the 4.9.99 kernel!

Regards,

Pete

It seems like something is missing. I get the "EPIPHANY_DEV file open failure" message when trying to run the eprime example. I'm not sure how to dig further on this.

Hi Pete.

I have not yet tried to build a new kernel so my Ubuntu 18.04 LTS platform still has the old kernel. If I recall correctly, there were some changes between the first parabuntu release and the last parabuntu release that required changes to many of the programs.

That said, make sure that these lines are at the bottom of the .bashrc file in the login directory you are using:

export PATH=/usr/local/browndeer/bin:$PATH export LD_LIBRARY_PATH=/usr/local/browndeer/lib:/usr/local/lib:$LD_LIBRARY_PATH export PATH=/opt/openmpi/bin:$PATH export LD_LIBRARY_PATH=/opt/openmpi/lib:$LD_LIBRARY_PATH export EPIPHANY_HOME=/opt/adapteva/esdk [ -e $EPIPHANY_HOME ] && . $EPIPHANY_HOME/setup.sh || echo Epiphany SDK not installed. export EPYTHONPATH=$EPYTHONPATH:/usr/local/include/epython/modules:/home/parau/epython

These are needed to get all the correct modules, libraries, and includes.

Next, try my working copy of eprime2, attached to this email.

Untar it somewhere under the login directory. Change into the eprime2 directory. There is a build.sh which will build the executable and there is a run.sh which will run the built program -- run.sh takes a number as an argument (not optional) -- start with 1000000 (1 million) and you can try going up from there although there is a limit because of the size of an integer on the parallella.

Best regards, Ted

Hi, Ted!

Thanks a bunch for helping me out. This is definitely a learning experience. But actually, its has been good. I’m learning a little at a time as I go.

Regards,

Pete

Hi Pete.

I have not yet tried to build a new kernel so my Ubuntu 18.04 LTS platform still has the old kernel. If I recall correctly, there were some changes between the first parabuntu release and the last parabuntu release that required changes to many of the programs.

That said, make sure that these lines are at the bottom of the .bashrc file in the login directory you are using:

export PATH=/usr/local/browndeer/bin:$PATH export LD_LIBRARY_PATH=/usr/local/browndeer/lib:/usr/local/lib:$LD_LIBRARY_PATH export PATH=/opt/openmpi/bin:$PATH export LD_LIBRARY_PATH=/opt/openmpi/lib:$LD_LIBRARY_PATH export EPIPHANY_HOME=/opt/adapteva/esdk [ -e $EPIPHANY_HOME ] && . $EPIPHANY_HOME/setup.sh || echo Epiphany SDK not installed. export EPYTHONPATH=$EPYTHONPATH:/usr/local/include/epython/modules:/home/parau/epython

These are needed to get all the correct modules, libraries, and includes.

Next, try my working copy of eprime2, attached to this email.

Untar it somewhere under the login directory. Change into the eprime2 directory. There is a build.sh which will build the executable and there is a run.sh which will run the built program -- run.sh takes a number as an argument (not optional) -- start with 1000000 (1 million) and you can try going up from there although there is a limit because of the size of an integer on the parallella.

Best regards, Ted

It seems like something is missing. I get the "EPIPHANY_DEV file open failure" message when trying to run the eprime example. I'm not sure how to dig further on this.

@njpacoma Hi, Ted. I updated the .bashrc, the line you have for EPYTHONPATH has added /home/parau/epython, which was missing.

I could not save the attachment for some reason. Would you please send it to me again? My email is boneoh at yahoo dot com. I tried several times, but the file never got saved from the email app. Very strange.

I really appreciate the help!

Regards,

Pete

Hello everyone!

As it appears, I'm a very late newcomer to the Parallella board. I have a microserver which I purchased recently intending to try it out for OCR work.

While trying to upgrade the latest "official" parabuntu image, I am struggling to get past Wily. On my first attempt I went the way described in https://linuxconfig.org/how-to-upgrade-to-ubuntu-18-04-lts-bionic-beaver#h9-how-to-upgrade-ubuntu-the-debian-way , but ended up with something that wasn't very functional so I started again.

Is there no way to do it the "ubuntu way"? Seems that Xenial and Bionic are missing the armhf packages or at least I have not been successful at finding them anywhere in the ubuntu repos. I am wondering whether something has changed in the time since previous solutions to this problem have been posted that's preventing me from success with this. If anyone is able to shine a light or possibly point me to a download link of a fully functional Xenial or Bionic image (Xenial would be ideal), I would appreciate it.

Thanks! guuberholtz

@guuberholtz Just a quick update on this one. I applied the method that @agent001 stated above by directly replace 'vivid' to 'xenial' (15.04 -> 16.04) and successfully upgraded to 16.04.

a) sudo sed -i 's/vivid/xenial/g' /etc/apt/sources.list b)for i in `find /etc/apt/sources.list.d/ -type f | xargs grep vivid -l`;do sudo sed -i 's/vivid/xenial/g' $i;done c) sudo apt-get update d) sudo apt-get dist-upgrade

One important note is that I ssh into the board and in the last step, I got disconnected during the 'dist-upgrade' then I just leave the board there without touching it for the whole night. it turned out to be fine. I know that it might be risky so take it for your own risk. ( in case of interrupted during dist-upgrade, the following 2 command will finally complete. In case of lost connection again, just use 'screen -r' to retrieve) e) sudo dpkg --configure -a f) sudo screen apt-get dist-upgrade -f

Run a quick test and it seems ok.

now you should customize the kernel config - I will attach here the version I'm using - just decompress it in the same folder you are currently: /home/yourprofile/kernel/linux-stable-rc
