I got my rapsberry pi compute module kit.
Unbox everything and inserted the Compute Module 3 on SO-DIMM connector of the IO Board.
J4 is set to EN
J3 is set to 3V3
I am using Ubuntu 14.04 as host pc.
sudo apt-get install libusb-1.0-0-dev
git clone --depth=1 https://github.com/raspberrypi/usbboot
cd usbboot
make
./rpiboot -v
This is end up at Cannot open file fixup.dat
What could be the problem !! Please help me

I have installed Raspbian Lite OS in Raspberry Pi zero.
I found that Raspbian Lite comes with Python3 as default.
But I am gonna run some scripts that uses libraries that are Python2 Compatible.
So I tried to change the default Python version from Python3 to Python2 (Specifically Python2.7.18)
After so much searching and trying, instructions from [this page][1] made my job
Now if I try to check in command writing
python --version
It shows me that it is Python2.7.18
But the problem is I am not being able to install any packages using
sudo apt-get install <python-packagename>
It shows me Errors like
1.Package "python-pip" has no installation candidate (When I tried to install pip)
2. Package python-numpy has no installation candidate (when I tried to install numpy)
3. unable to locate package python-pyaudio (when I tried to install pyaudio)
I am searching but no solution.
Can anyone please help? I am frozen in a critical stage of my project .
Generally, for new raspbian/raspios os with python 3 by default, it is not suggested to replace the system python interpreter to python 2, it may break some system component's dependency.
Instead, you can create a python 2 virtual env, if you need to run python2 scripts.
sudo apt-get install python3-pip
pip install virtualenv
virtualenv -p /usr/bin/python2.7 venv
source venv/bin/activate
You can test the python version as following,
(venv) $ python --version
I am trying to install vscode onto my raspberry pi.
I have tried going to the vscode website to download it, but when I try to install it I get the error "failed to install file". I am not sure what to do.
It's simply not supported at this time. The linux versions made available on the official download page are for Linux PCs, not Raspberry Pis. The error you get belies this incompatibility. The only means of getting Code on a Pi is via unofficial ports, as outlined in the link provided by the other answerer.
Not officially supported, but you can install this unofficial build, open up a terminal on the Pi:
sudo su
. <( wget -O - https://code.headmelted.com/installers/apt.sh )
More information here
If it fails to install (authentication issues), you can force it with:
sudo apt install code-oss libnspr4 libnss3 libsecret-1-0 libsecret-common libxkbfile1 --allow-unauthenticated
There is a distro for Raspberry Pi, Jetson Nano and similar ARM A Linux devices.
wget https://packagecloud.io/headmelted/codebuilds/gpgkey -O - | sudo apt-key add -
curl -L https://raw.githubusercontent.com/headmelted/codebuilds/master/docs/installers/apt.sh | sudo bash
If you want to type code instead of code-oss, then:
cd /usr/bin && sudo ln -s code-oss code
I followed an instruction to set up a Movesense development environment, "Manual setup on Linux", from Suunto / Movesense-community / Movesense-device-lib, README.md
However, I got stuck at sudo apt-get install gcc-arm-embedded:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package gcc-arm-embedded
How can I move forward?
I used Ubuntu 17.10 (Artful Aardvark) as a guest OS.
Try adding the repository:
sudo apt-get remove gcc-arm-none-eabi gdb-arm-none-eabi binutils-arm-none-eabi
sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt-get update
I downloaded it directly from ARM IIRC:
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
Following the instructions under "GNU/Linux" in the "GNU ARM Embedded Toolchain" section of
https://gnu-mcu-eclipse.github.io/toolchain/arm/install/#gnu-arm-embedded-toolchain
Summarized:
// Get some support dependencies for 32 bit running on 64-bit machines
// Check toolchain README for actual list.
$ sudo apt-get -y install lib32z1 lib32ncurses5 lib32bz2-1.0
// Install the toolchain
$ mkdir -p "${HOME}"/opt
$ cd "${HOME}"/opt
$ tar xjf ~/Downloads/gcc-arm-none-eabi-7-2017-q4-major-linux.tar.bz2
$ chmod -R -w "${HOME}"/opt/gcc-arm-none-eabi-7-2017-q4-major
You will likely have to modify some of the build files in the Movesense project to point to this location for it to build.

I had some trouble installing it on a Windows machine and tried out Vagrant. This makes the development environment highly movable and in sync if you have multiple developers working on the project.
I drill down to the folder where bfgminer.exe lives on my Raspberry Pi with Raspbian OS and issue this command:
screen -S Mining .bfgminer –o http://mint.bitminter.com:3333 –u username.myname –p 123
I get a command not found message. I have tried everything I can think of to get the syntax correct. Where am I going wrong
You need to install screen if it's not installed by default:
sudo apt-get install screen
I'm trying to install NetBeans on Linux Mint, and I'm getting the following error every time I run the installation script:
Configuring the installer...
Searching for JVM on the system...
Extracting installation data...
Running the installer wizard...
Can`t initialize UI
Running in headless mode
What should I do to get it working?
In case anyone has this problem in the future, Netbeans doesn't like OpenJDK 6 but -- fortunately -- it works fine with OpenJDK 7 (as expected as for Java 7 OpenJDK is the reference implementation). Just make sure you remove any Java 6 packages before installation attempts. On Ubuntu and Mint one can do:
sudo apt-get purge ^openjdk-6-*
sudo apt-get install openjdk-7-jdk
It should work afterwards.
Looks like Netbeans does not work properly with Openjdk. This is what I did (in Linux Mint 12):
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
Then you will be able to run the .sh installer as usual.
I hit this same issue on Kubuntu 12.04 LTS but needed Sun JDK 6 for a project I'm maintaining. I stumbled upon Martin Wimpress' OAB-Java script (by way of help.ubuntu.com) which creates and installs a local apt repository for Sun JDK 6. You can find the latest instructions on Martin's github site which run as follows:
cd ~/
wget https://github.com/flexiondotorg/oab-java6/raw/0.2.7/oab-java.sh \
-O oab-java.sh
chmod +x oab-java.sh
sudo ./oab-java.sh
If you want to see what this script is doing while it is running then execute the following from another shell:
tail -f ./oab-java.sh.log
Alternatively, you can clone the OAB-Java repo and kick of the script from within it:
git clone git://github.com/flexiondotorg/oab-java6.git
cd oab-java6
sudo ./oab-java.sh
Either way, once that is in place follow Jose's instructions to remove openjdk and install sun jdk:
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
One final note, the script accepts a -7 argument which will create and install a local apt repository for Oracle JDK 7 should you want to go that route.
I was able to get it to work by getting into the target system using ssh -X, then making sure DISPLAY was exported. That handles the X server issues.
Change the priority of the Oracle Java executables:
export PATH=/usr/java/latest/bin:$PATH
Run the installer:
./netbeans-8.1-linux.sh
What worked for me was installing default java environment from the terminal:
sudo apt-get install default-jre
The installation was a success - under "user".
The installation failed - under "su" (under Red Hat equivalent of "sudo"). With
Can`t initialize UI
Running in headless mode
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
For me.
