Mender upgrades across L4T releases (and yocto branches) are not currently supported #14

Open dwalkes opened 3 years ago

dwalkes commented 3 years ago

Partition layout changes on L4T releases have made this not trivial to support for older yocto branches.

Changes are coming with L4T version 32.6 which we may be able to leverage to upgrade from older branches, and no partition changes are planned from r32.5 (gatesgarth) forward at this time.

See OE4T meeting notes at this link and watch meeting updates in this link for more information.

See this sheet which tracks some combination of changes to partition layout between releases and has some references to associated xml files where these changes are tracked.

See this commit which backs out a feature to support u-boot environment partition migration between releases, which could be useful for TX2 u-boot based mender implementations.
