Topics

• Which LTS branch will we target with Jetpack 6?
  • New LTS branch Scarthgap coming in April
  • Plan we’ve discussed before was to target Scarthgap with Jetpack 6, keep Kirkstone as Jetpack 4 and 5.
  • Probably will be a while before deploying Jetpack 6 in production, should have time to do Scarthgap transition.
  • Likely will drop Dunfell branches from maintenance once this transition takes place.
  • If anyone really wants to stay on Kirkstone but bring in Jetpack 6 please speak up and volunteer to help with this.
  • Discussed about bringing Jetpack 5 into Scarthgap as 35.x branches, similar to what we are doing on Kirkstone, will tentatively plan to do this.
    • Kirkstone machine learning content is outdated, many people stranded on Jetpack 5 due to hardware limitations will likely want to use Scarthgap.
  • Will tentatively plan to take the current master support for 35.x onto the Scarthgap branch when the Scarthgap release is available.
• Swupdate example and open source home
  • See discussion at https://groups.google.com/g/swupdate/c/Kh2XlA5rwzE/m/oTgDfFRnAQAJ
  • Dan plans to retarget in tegra-demo-distro instead of attempting to host upstream, based on maintainer's feedback.
• Mender support for JP5 PR.
  • See https:/OE4T/meta-mender-community/pull/19
  • Some interest discussed at the end of the meeting, others who have volunteered to help with this.
• Updates for Metropolis Microservices for Jetson
  • See https://docs.nvidia.com/moj/setup/quick-start.html and https://developer.nvidia.com/blog/bringing-generative-ai-to-the-edge-with-nvidia-metropolis-microservices-for-jetson/?ncid=so-nvsh-145160
  • Only supported on Jetpack 6 developer preview at this time.
• Jetpack 6 secureboot
  • Ilies is currently working on this.
  • Debugging issues between stock L4T and our distro.
• Several issues/discussions around creating a custom MACHINE config
  • See latest here
  • Need an update to the wiki page at https:/OE4T/meta-tegra/wiki/Creating-a-custom-MACHINE regarding flashvars
  • Hints in the discussion about using the dtsi about disabling the EEPROM read if your custom carrier doesn’t have an EEPROM.
• Pinmux selection for headless boards
  • Only option is HDMI or displayport for some pin configurations
  • Discussed related cbb kernel panic for display init.
  • See discussion here.
  • See related forum post at https://forums.developer.nvidia.com/t/cbb-causing-a-kernel-panic/254297
• Recent/upcoming updates in holoscan
  • Jetpack 6 support
  • Updating dGPU drivers, cuda
  • Recipes for pytorch, other recipes for holoscan sdk
  • Will align with the device preview branch on meta-tegra
  • May make sense to bring dGPU into meta-tegra in the future.
• Yocto summit discussion on OE developer day RE machine learning layer
  • Interest for working group within openembedded to coordinate efforts on different platforms.
  • Ian has tentative interest in moving recipes from holoscan to a shared layer.
