High-Level Assessment

The following are alternative approaches to this PR:

1. Reuse shared ISP profiles

• ➕ Could avoid shipping duplicate image-quality data where profiles are identical.
• ➕ Could reduce maintenance of large tuning files.
• ➖ Requires verifying profile equivalence and how shared files are packaged.
• ➖ Could obscure intentional device-specific tuning.

Recommendation: Keep the device-specific profile and startup tuning: they fit the repository's board-overlay approach. Before merging the large ISP files, check whether identical profiles can safely be reused, particularly for a flash-constrained image.

1. The device's exclude list has the wrong name 📘 Rule violation ≡ Correctness

Description

The new exclusion list is named gk7205v300_lite.list, but the defconfig identifies the board's SoC
and flavor as gk7201v200 and lite. Because exclusions are selected by SoC and flavor, this
board's list is not selected, leaving unused sensor files and modules in its space-constrained
rootfs image.

Code

+/etc/sensors/4l_sc223a_i2c_1080p.ini

Evidence

The defconfig declares the gk7201v200 SoC and lite flavor, and the repository's _.list naming
convention requires gk7201v200_lite.list for this board. The added file is instead named
gk7205v300_lite.list, so it does not match the board's exclusion-list name.

2. The new device is absent from the README ✓ Resolved

Description

The PR adds a build-discoverable defconfig for gk7201v200_lite-rtl8733bu-16mb without adding a
corresponding row to the README device inventory. Readers consulting the published list of supported
devices cannot find this board there.

Code

+# Architecture
+BR2_arm=y

Evidence

Checklist item 7 requires a README row for each new device. The added defconfig establishes this
device, but the README device inventory contains no corresponding entry.

3. The new sensor profile is never selected ✓ Resolved

Description

customizer.sh sets neither the sensor boot variable nor .isp.sensorConfig for the added SC2336
profile. On first boot without a previously correct sensor selection, the camera retains a missing
or different sensor setting instead of using the configuration supplied for this board.

Code

devices/gk7201v200_lite-rtl8733bu-16mb/general/overlay/usr/share/openipc/customizer.sh[R11-13]

+# Set custom majestic settings
+#
+cli -s .nightMode.irCut off

Evidence

The PR supplies an SC2336-specific sensor configuration but has no reference to it or sensor
assignment in its customizer. Existing device customizers show both boot-variable sensor selection
and explicit selection of a board-specific sensor INI.

4. First boot leaves the WiFi profile unset ✓ Resolved

Description

customizer.sh comments out its only fw_setenv wlandev command, whose example names gk7205v200
rather than this board’s gk7201v200 SoC. On first boot without a pre-existing Wi-Fi profile,
customization sets other environment values but leaves the selected RTL8733BU module without a
board-specific profile, so the Wi-Fi tuning service may wait for a wlan0 interface that is never
created.

Code

devices/gk7201v200_lite-rtl8733bu-16mb/general/overlay/usr/share/openipc/customizer.sh[26]

+#fw_setenv wlandev rtl8733bu-gk7205v200-camhi

Evidence

The only board-specific wlandev assignment in the customizer is commented out, although the
defconfig selects the RTL8733BU package and identifies the SoC as gk7201v200. The new tuning
service requires wlan0, and another RTL8733BU board actively sets its profile in its customizer;
together, these show why leaving the assignment inactive matters on a camera without a pre-existing
profile.
