Topics

• Release 35.5.0
  • Have work in progress branch
  • Usable for testing
  • Everything builds with latest oe-core master.
  • Only have done basic smoke testing.
  • Particularly worried about graphic stuff, wayland in particular.
  • Minor update overall
  • No cuda changes.
  • Should be merged to master quickly.
  • Will be the base for scarthgap. Will also plan to backport to kirkstone.
  • Container testing also needed on on 35.5
  • Changed flash layouts to add tags to partitions. Might be something to look out for. Otherwise nothing which would significantly impact anyone.
  • Latest secure boot at https://docs.nvidia.com/jetson/archives/r35.5.0/DeveloperGuide/SD/Security/SecureBoot.html and https://docs.nvidia.com/jetson/archives/r35.5.0/DeveloperGuide/SD/Security/SecureBoot.html#sd-security-secureboot-uefipayloadencryption
    • Using Orin AGX, Industrial, Nano.
    • UEFI payload encryption and changes to EKB, not working properly yet.
    • Introduced firmware DPM. Not covering all paths yet.
• Release 36.2 Developer Preview
  • Have work in progress branch
  • Usable for testing
  • Latest container toolkit does away with the c language version custom for jetson (“legacy mode”) which did the mapping of the passthrough from host OS into the container. Moved all the .csv file mapping logic into the go code part of the container toolkit.
  • Not convinced docker support is 100% there, additional changes we could make to use the csv file as-is rather than manual modifications based on whether it’s in the same filesystem tree or something installed directly in the rootfs.
  • GA likely coming soon from NVIDIA.
• swupdate PR
  • See https://github.com/OE4T/tegra-demo-distro/pull/293
  • Will merge this after 35.5
  • Might want to update the l4t loader. In the same place the capsule payload is moved to the ESP partition, l4t loader lives there too. Only a single copy of it. Had been replacing with the updates.
  • Other suggestion: could possibly do a binary diff of the content of the partition, only replace if not the same.
• Docker image
  • See related discussion in OE4T/community at this link.
  • Some interest mentioned from others
  • Stock L4T storage layouts all now include a UDA partition. Used to be at the end and filled to end of device.
• scarthgap status on poky/oe-core
  • M3 feature freeze built with one QA failure for beaglebone black and X11. May need a re-spin
  • Recipes in master-next which may or may not be chosen based on breakage.
  • May release LTS 5.0 early in April rather than end of April.
  • Dunfell will go out of support in the May timeframe.
  • meta-openembedded hasn’t created scarthgap branch yet.
  • go upgrades, rust upgrades, lots of improvements.
  • If you can switch to the LTS soon may be worth looking at immediately.
  • Will create a scarthgap branch after 35.5 goes into master.
  • bitbake-layers layerindex-fetch <layer> won’t work when using scarthgap in some cases.
• Flashing issues with doflash or initrd-flash
  • See related chat here and issue here.
  • Sometimes a partition flash fails
  • Kernel logs show USB issues in some cases.
  • Please share any findings in the chat or on wiki pages.
