The release image now targets the 200 MiB factory eMMC slot: content plus 40 MiB working space, hard build failure past the slot size. The raw ext4 is deployed alongside the wic; scripts/mkfw.sh packs it into a signed .fw with factory-pattern upgrade.a/upgrade.b tasks. fwup 1.16.0 recipe (applies ForgeFIRM and Glowforge-signed archives on device) is installed in both images. Dev images stay SD-sized with a 256 MiB working margin and no ceiling. Verified on the 20260808153331 build: release ext4 180.8 MiB; signed .fw applies byte-exact with fwup 1.16.0 and with the factory's 0.14.2 (raw-format pubkey), and 0.14.2 -V verifies the signature.

# ForgeFIRM cuts the cloud dependency: drop the Glowforge cloud client
|
|
# (gfui-client connects to Glowforge's servers). Removing it here (override
|
|
# only; the shared glowforge-image base is untouched) also sidesteps its
|
|
# do_package failure. Its slot is filled locally by forgectrl (camera MJPEG
|
|
# service; the grblHAL controller recipe is tracked in kas/README.md
|
|
# backlog #5).

|
|
# gfhome: one-shot Glowforge web-service homing, invoked by the controller

|
# for $H when homing_mode = gfcloud (/data/forgefirm.conf).
|
|
# v4l-utils provides media-ctl / v4l2-ctl for the imx-media pipeline (also a

# forgectrl runtime dependency, kept explicit here for bring-up use).
