# Additional pin — the MCUboot serial-recovery fixtures `serial_recovery` and

# tag: 27c54835 https://github.com/intercreate/smp-server-fixtures/releases/tag/27c54835

# zephyr: main f33aa2bc (post-4.4.0)
#
# MCUboot's raw (non-console) serial-recovery protocol (BOOT_SERIAL_RAW_PROTOCOL,
# mcu-tools/mcuboot#2755) merged after 4.4.0's MCUboot pin, so this one fixture is
# built from a post-4.4.0 Zephyr `main` commit. Its artifact name carries the
# c8f44c41 release hash and so does not collide with the 0eae053d set. `manifest.json`
# and `SHA256SUMS` are therefore a local merge: the 0eae053d baseline plus this
# fixture's manifest entry + digests (the `manifest.json` digest line was refreshed
# to match the merge). When 0eae053d's Zephyr next includes #2755, re-vendor the whole
# set from a single release and drop this note.
# Two MCUboot recovery features landed after 4.4.0's MCUboot pin: the raw
# (non-console) protocol (BOOT_SERIAL_RAW_PROTOCOL, mcu-tools/mcuboot#2755) and the
# serial-recovery MCUmgr params command (BOOT_MGMT_MCUMGR_PARAMS, mcu-tools/mcuboot#2746,
# intercreate/smp-server-fixtures#10), so both recovery fixtures are built from a
# post-4.4.0 Zephyr `main` commit. Their artifact names carry the 27c54835 release hash
# and so do not collide with the 0eae053d set. `manifest.json` and `SHA256SUMS` are
# therefore a local merge: the 0eae053d baseline with these two recovery entries (+
# digests) swapped in. The `serial_recovery_buf<N>` matrix stays on 0eae053d (it is
# exercised in app mode, where recovery params do not apply). When 0eae053d's Zephyr
# next includes #2755 and #2746, re-vendor the whole set from a single release and drop
# this note.
#
# To bump: re-download the artifacts + SHA256SUMS + manifest.json from a newer
# per-commit release and update the `tag` above.
