Repository Definitions for Concurrent Real-Time Products

Concurrent Real-Time APT repository definitions take the following form:

deb [arch=arch] 7.3 core

The black portions of the definition are common to all Concurrent Real-Time repositories.

The purple portion specifies the architectures available in the repository. You should replace it with one or more of the following abbreviations: i386, amd64, arm64. If more than one architecture abbreviation is to be specified, they must be separated by commas without any intervening white space.

The bold green portions above must be replaced with your Login ID and Password for (previously know as That information is included in a cover letter which shipped with your system and/or software. The Login ID is also your Site ID, which typically starts with LI, LA, or LR followed by 5-7 decimal digits. If you cannot readily locate these values, please contact Concurrent Real-Time Software Support as described in the last section on this page.

The bold red portion of the definition specifies the name (or path) of the repository.

The bold blue portion is the product version.

The bold orange portion lists the product components of interest. Multiple components can be specified and must be separated by white space. Only include the components which you have purchased. Specifying unauthorized components will result in errors during the APT database update process and may prevent access to other valid components.

The following sections available describe the architecture, name/path, version, and components for repository definitions for Concurrent Real-Time products.

RedHawk Linux

Target System Arch Name/Path Versions Components
Intel/AMD Systems amd64 redhawk/generic 7.3 thru 7.3.2 core fbs rcimgps
APM XGene-C1 arm64 Only available under ARM64 RPM Repositories
NVIDIA Jetson TX1 arm64 redhawk/tx1 6.5 core
NVIDIA Jetson TX2 arm64 redhawk/tx2 7.3 core

For example:

deb [arch=arm64] 7.3 core


deb [arch=amd64]!/redhawk/generic 7.3 core fbs


Target System Arch Name/Path Versions Components
32-bit Intel/AMD i386 nightstar 4.5 rt
64-bit Intel/AMD amd64,i386 nightstar 4.5 rt
NVIDIA Jetson TX1 arm64 nightstar 4.5 rt
NVIDIA Jetson TX2 arm64 nightstar 4.5 rt
NVIDIA XGene-C1 arm64 nightstar 4.5 rt

NightStar is one of the repositories that contain multiple archtectues. If you wish to be able to debug 32-bit programs on a 64-bit system with NightView, you need to add ",i386" to the architecture portion of the repository definition:

deb [arch=amd64,i386] 4.5 rt

By default, the Debian and Ubuntu apt/dpkg mechanism does not allow multiple architectures in repository definitions. You must enable them via commands equivalent to the following:

dpkg --print-foreign-architectures | egrep -e 'i386'>/dev/null || dpkg add-architecture i386;


Target System Arch Name/Path Versions Components
64-bit Intel/AMD amd64 maxada 3.5.1 core

For example:

deb [arch=amd64] 3.5.1 core
