Topics

  • Capsule updates pull request at this link
    • Having host side tools available through native recipe is probably a good approach, might be able to do a separate recipe, similar to uboot-tools recipe in oe-core.
    • Hook service to signing server - planning to add stub function - default uses variables in build environment and pass to capsule creator so it is signed. Isolate into a function which can be replaced by an external signing system. Dedicated image type might be OK but may be extra effort. Just using a recipe with correct output is fine.
    • Discussed leaving BUP generation in for a while and then phasing out BUPs eventually. Logic for handling different cases with or without initramfs/bundled is duplicated. Would be nice to eliminate this as it’s a source of error. Would be nice if going into an LTS branch we do that slowly and don’t introduce breakage.
  • Code organization regarding mender and open pull request
    • tegra-demo-distro pull request here.
    • meta-mender-community pull request here.
    • Proposal is to separate two meta layers for Jetpack 4/5 into one branch with two subdirectories, linking only one or the other in your layer using the link.
    • Matt’s suggestion is to use a mechanism which defines overrides based on L4T versions, using this to define which overrides/flash packagers to use. Might be a pain to maintain but is simpler for users. Doesn’t require the user to specify different branches or sublayers.
    • Plan to stage Jetpack 5 support in the fork for now, then will revisit upstream plan
    • Proposal to move the tegra-demo-distro distro related content into another subdirectory which can be optionally included for folks who want to use a demo distro, will only be supported on Jetpack 5 and later. Mender layers for meta-arm and meta-ti do an approach to include several optional sub-layers.
      • Would introduce a hard breaking change if the layer moves around
      • Would be an add-in layer for anyone’s build which enables mender bits on the Jetson platforms, wouldn’t need to be strictly tied to the demo distro. Tied to distro policy for implementing mender OTA solution.
      • Josef will help with the scaffolding setup for the new distro in meta-mender-community
  • EOSS presentation status
    • See the talk here.
  • r35 L4T release likely coming this fall.
    • Matt will be unavailable for the month of November, may need additional help for any L4T releases which come during this timeframe.
    • Looking for ideas to help with the next release deployment.
    • Ideally would like some corporate partners who could devote some resources/sprints to either development or testing.
    • Brennan has the ability to send hardware out for meta-tegra people who can participate and are in need of hardware.
