cv200 family, gk7201v200: build and publish the split NOR image on every device by openipc-ai · Pull Request #222 · OpenIPC/builder

openipc-ai · 2026-11-02T09:55:43Z

Problem

OpenIPC/firmware#2668 moved four generic profiles to the split NOR layout (uImage and squashfs in one firmware partition that the kernel divides at boot): hi3516cv200_lite, hi3518ev200_lite, hi3518ev200_ultimate and gk7201v200_lite. A camera on that layout takes only a -split package. Offered a device's plain package, sysupgrade refuses:

This camera runs the split NOR layout and upgrades from firmware.bin (openipc.hi3518ev200-nor-lite-split.tgz), not a separate kernel and rootfs. Nothing was written. Aborting.

That's how the OpenIPC/firmware#2675 camera met it, fixed for its own device in #221. None of the eleven devices built on those four profiles has the split layout, so any of them that has been on the generic image can't come back to its own.

Change

Exactly what #221 did for the Baolian, and firmware#2668 for the profiles:

All 11 defconfigs:

BR2_ROOTFS_POST_IMAGE_SCRIPT="$(BR2_EXTERNAL_GENERAL_PATH)/scripts/post-image-split.sh"
BR2_OPENIPC_NOR_FIXED_PACKAGE=y

The 4 devices that ship their own kernel config (trassir-tr-d4121ir1-v2, lenovo-snowman-1080p lite and ultimate, vstarcam-c8892wip) get, appended where firmware's configs have them:
```
CONFIG_MTD_ROOTFS_ROOT_DEV=y
CONFIG_MTD_SPLIT_FIRMWARE=y
CONFIG_MTD_SPLIT_FIRMWARE_NAME="firmware"
CONFIG_MTD_SPLIT_SQUASHFS_ROOT=y
CONFIG_MTD_SPLIT_UIMAGE_FW=y
```
The other 7 build with firmware's generic kernel configs, which have these since #2668.

Device	defconfig	kernel config
gk7201v200_lite_xm-7205-rtl8733bu-16mb	split lines	firmware's
hi3516cv200_lite_spezvision-svi-252b-k202	split lines	firmware's
hi3516cv200_lite_trassir-tr-d4121ir1-v2	split lines	own, + MTD_SPLIT
hi3518ev200_lite_lenovo-snowman-1080p	split lines	own, + MTD_SPLIT
hi3518ev200_lite_qtech-qvc-ipc-136w	split lines	firmware's
hi3518ev200_lite_smartwares-cip-37210	split lines	firmware's
hi3518ev200_lite_switcam-hs303	split lines	firmware's
hi3518ev200_lite_switcam-hs303-v2	split lines	firmware's
hi3518ev200_lite_vstarcam-c8892wip	split lines	own, + MTD_SPLIT
hi3518ev200_ultimate_lenovo-snowman-1080p	split lines	own, + MTD_SPLIT
hi3518ev200_ultimate_tplink-kasa-kc110	split lines	firmware's

What stays the same:

Fixed-slot package: still made while it fits, for cameras whose sysupgrade predates the split layout. A build whose rootfs has outgrown its slot ships the split package alone, with a warning, instead of failing. hi3518ev200_lite_switcam-hs303 is in that case today: its master build fails 20 KB over the 5120 KB slot.
NAND: a NOR+NAND ultimate still packages its NAND image whichever NOR layout it ships.
Publishing: the workflow publishes <device>-nor-split.tgz (Imou Cue 2: build and publish the split NOR image #220), and sysupgrade finds it beside the plain package named in upgrade (firmware#2743).

hi3518ev200_lite_lenovo-snowman-1080p is in NOT_BUILT, so CI doesn't build it. It gets the same lines for consistency, but nothing here exercises them.

Tested

python3 .github/scripts/ci-matrix.py --self-test → self-test ok (130 devices, 16 smoke, 39 cases). The selector builds the 10 built devices.
Boot test in QEMU (qemu-bench, hi3516cv200 machine): results to follow in a comment, once CI has built the images.
Not on a camera.

…ery device Since OpenIPC/firmware#2668 the generic hi3516cv200_lite, hi3518ev200_lite, hi3518ev200_ultimate and gk7201v200_lite images use the split NOR layout: uImage and squashfs in one "firmware" partition the kernel divides at boot. A camera on that layout takes only a -split package; offered a device's plain one, sysupgrade refuses ("This camera runs the split NOR layout ... Nothing was written"), which is how the #2675 camera met it (fixed for its own device in #221). None of the eleven devices built on those four profiles had the split layout. Each gets what #221 gave the Baolian and firmware#2668 gave the profiles: the post-image script and BR2_OPENIPC_NOR_FIXED_PACKAGE in the defconfig, and, for the four that ship their own kernel config (trassir, lenovo-snowman lite and ultimate, vstarcam), CONFIG_MTD_SPLIT_* with CONFIG_MTD_ROOTFS_ROOT_DEV; the other seven take firmware's, which has them. The fixed-slot package is still made while it fits, and a NOR+NAND ultimate still packages its NAND image either way. The workflow publishes <device>-nor-split.tgz (#220); sysupgrade finds it beside the plain one (firmware#2743).

Publish split NOR images for 11 cv200-family and GK7201V200 devices

🐞 Bug fix ⚙️ Configuration changes 🕐 20-40 Minutes

AI Description

• Enable split NOR packaging for 11 devices whose generic profiles already use the split layout.
• Add firmware-partition splitting support to four device-specific kernel configs.
• Retain fixed-slot packages when they fit, preserving upgrades for older cameras.

High-Level Assessment

Extending the existing split-image script and publication path is the appropriate approach. A separate packaging mechanism would duplicate established firmware behavior without addressing the need for matching options in device-specific kernels.

QEMU boot results (qemu-bench SoC models). Each split image is this PR's CI artifact (run 41424624362) at commit 889ce21. These are emulated boots, not cameras.

Method. I placed firmware.bin from each *-nor-split.tgz at 0x50000 on a blank flash (8 MB, or 16 MB for the 16 MB devices) attached to hi_sfc. I booted with -kernel <uImage cut from firmware.bin> and the cmdline the split layout gives, mtdparts=hi_sfc:256k(boot),64k(env),-(firmware) root=/dev/mtdblock4. Each boot passes when the kernel splits firmware itself, mounts the squashfs from the split, and init reaches the login prompt.

Every boot logged 2 uimage-fw partitions found on MTD device firmware and 1 squashfs-split partitions found on MTD device rootfs.

Baseline. The current latest release of hi3518ev200_lite_vstarcam-c8892wip-nor.tgz has an own kernel config without MTD_SPLIT. Packed into the same split layout, it gets only the 3 cmdline partitions, then VFS: Cannot open root device "mtdblock4" ... error -6 and a kernel panic. That is what a split sysupgrade would do to these cameras without the kernel lines here.

Packages.

hi3518ev200_lite_switcam-hs303 now ships -nor-split.tgz only. Its rootfs is over the 5120 KB fixed slot, which is also why latest has no package for it today.
The other devices ship both NOR packages. The two ultimate devices ship their -nand.tgz too.

Not covered.

hi3518ev200_lite_lenovo-snowman-1080p is in NOT_BUILT, so CI didn't build it. Its kernel config change is the same five lines as the ultimate snowman, which booted.
fw_printenv complains about /etc/fw_env.config on some devices in QEMU. The env sector of my test flash is blank, and the same image on the classic fixed layout logs the same 13 lines, so this is not from split.
No camera has run these images.
