Intent

Support of a great OOB experience with a desktop environment and a rich set of Linux libraries available and tested as part of the Ubuntu community.   Intended initially as an evaluation and early development platform on Kria, it can also be used for production with Canonical's assistance.

Embedded Linux development tool focused on Xilinx silicon and device specific feature enablement via board support packages (BSPs) and pre-built reference(s).

Updates

Kria Ubuntu OS is a Canonical certified OS that is supported with regular updates (e.g. security patches) from Canonical.  A new LTS  version of Ubuntu is provided every two years and each release is supported by Canonical for up to 10 years.

Snapshot image release aligned with Xilinx tools release (e.g. 2022.1) with no regular/planned updates until next  Xilinx tools release (e.g. 2022.2). 

Pre-built apps

Kria example application final end-to-end verification and pre-built public release will be to the Ubuntu OS. 

Kria example applications will build inside the PetaLinux tool but will not be fully verified nor released as pre-built packages. 

Application customization

User can customize userspace applications via on-target development and/or standard Ubuntu development tools/workflows.

User can customize userspace applications via on-target development and/or PetaLinux supported cross-compilation environment.

Kernel customization

LTS certified kernel is maintained by Canonical. User can modify and build their own derivative kernel but is then outside the scope of the certified image and Canonical support.   

Tool enables full customization of the kernel. 

Path to production

If user requires an officially certified and supported Ubuntu OS for their production system they must reach out to Canonical.  Production systems are assumed to have custom hardware (carrier card or chip down).  If any modifications to Ubuntu are needed to support custom hardware customers are encouraged to engage directly with Canonical to maintain certification.   https://ubuntu.com/support 

Canonical has very strict rules about what can be labeled as Ubuntu - please see more here: https://ubuntu.com/legal/intellectual-property-policy

User can use the PetaLinux and or Yocto to create their own fully custom embedded Linux. 

Development Flow

On-target compilation. Cross-compilation.  Sysroot provided by Canonical. 

On-target compilation. Cross-compilation. Sysroot provided by Yocto eSDK - Tight integration with Vivado & Vitis tool sets.
