Discussion

Nvidia announcement regarding alignment with OE4T

  • Jetpack 7.2 publicly reported support for OE4T/Yocto
  • Would like to hear from community about what that alignment should look like.
  • Meeting monday with Nvidia at this link.
  • Considering formal legal structure for the project. Have discussed Linux Foundation.

Jetpack 7.2 update

  • JetPack 7.2 content goes into master, then gets back-ported to wrynose . If all goes well, this will happen over the next couple of weeks.
  • The wrynose branch will continue to get JetPack 7.x updates as NVIDIA releases them (but master first, as usual).
  • The scarthgap branch will remain active until April 2028. If/when NVIDIA releases any maintenance updates for JetPack 6/L4T R36.x, those will go into that branch.
  • The scarthgap-l4t-r35.x branch will also stick around until 2028, PRs will be welcome to fix issues there, but it will not otherwise be active.
  • All other non-LTS branches will be deprecated, including the master-l4t-r38.2.x and master-l4t-r38.4.x branches that were initially set up for the Thor-only early JetPack 7 releases. (That mainly means branches like whinlatter that went EOL upstream when wrynose was released.)
  • Latest tegra-demo-distro tree at https://github.com/OE4T/tegra-demo-distro/tree/wip-l4t-r39.2.0
  • Draft PR open at https://github.com/OE4T/meta-tegra/pull/2247
  • Missing a couple of kernel modules for audio which will be coming in soon.
  • linux-tegra kernel has a problem with rollback on the bootloader, so start with noble kernel for any update testing.
  • /dev/mem ideally should not be used going forward.
  • Hope to have the merge done this month.
