ssc338q_rubyfpv_generic-nor.tgz rootfs does not include SigmaStar userspace libs — majestic cannot start

[wkumik]

Root cause

The ssc338q_rubyfpv_generic-nor.tgz artifact does not include the SigmaStar userspace libraries that majestic is linked against. The kernel modules are bundled (mi_venc.ko, mi_vpe.ko, etc. under /lib/modules/4.9.84/sigmastar/) and /usr/bin/majestic is present, but the libmi_*.so / libcus3a.so / libispalgo.so / libcam_os_wrapper.so family is absent from the rootfs. Result: majestic exits immediately on launch, Ruby never gets a video source, GS sits on "waiting for video feed".

The libs are not hidden elsewhere — find / -name 'libmi_*.so' returns zero matches, and /rom/usr/lib/ (the raw squashfs) has 87 .so files but none from the SigmaStar SDK. They are simply not in the firmware image.

Repro

Hardware: Runcam WiFiLink 2 (SSC338Q + IMX415, 16 MB NOR, IMX415 sensor).

1. Download https://github.com/OpenIPC/builder/releases/download/latest/ssc338q_rubyfpv_generic-nor.tgz
2. Flash uImage.ssc338q → /dev/mtd2, rootfs.squashfs.ssc338q → /dev/mtd3, reboot.
3. Telemetry and radio link come up; GS (Ruby 11.7) reports "waiting for video feed" indefinitely.

Evidence

/etc/os-release:
```
OPENIPC_VERSION=2.6.04.14
BUILD_OPTION=rubyfpv
TIME_STAMP=1776145779
```

ldd /usr/bin/majestic → 20 libraries "not found":
```
libmi_ai.so libmi_ao.so libmi_divp.so libmi_isp.so libmi_rgn.so
libmi_sensor.so libmi_sys.so libmi_venc.so libmi_vif.so libmi_vpe.so
libcus3a.so libispalgo.so libcam_os_wrapper.so libcam_fs_wrapper.so
libmi_ipu.so libmi_ive.so libmi_shadow.so libmi_vdf.so libMD_LINUX.so
libmi_iqserver.so
```

Launching manually:
```
/usr/bin/majestic: error while loading shared libraries: libmi_ai.so: cannot open shared object file: No such file or directory
```

Ruby router log (consequence):
```
S3-0:00:11.448 000 Router: SOFTERROR: [VideoSourceMaj] Start program: Can't find the PID of majestic
```

Expected

The rubyfpv artifact should either bundle the SigmaStar userspace SDK (so majestic actually runs) or not ship /usr/bin/majestic at all. Currently the image promises a video source it cannot provide.

For comparison, Runcam's own WiFiLink2_Ruby_V11.1(b286) NOR image on the same hardware works — majestic launches cleanly, video streams. That image ships libmi_*.so etc. in /usr/lib/.

Workaround

Flash Runcam's official Ruby 11.1 image from https://www.runcam.com/download/runcamwifilink2 — loses newer Ruby features (11.8 vs 11.1) but video works.

Note

rubyfpv.com currently recommends this exact broken artifact for SSC338Q users: https://rubyfpv.com/setup_openipc.php — worth cross-linking if/when this is fixed.

Environment

• SoC: SSC338Q + IMX415 (Runcam WiFiLink 2)
• Flash: 16 MB NOR. mtd layout: boot / env / kernel (2M) / rootfs (8M) / rootfs_data (5.6M)
• Kernel: Linux 4.9.84 ssc338q

I'm experiencing a similar issue in my custom Ultimate build for the Tapo C110 ip cam.

This is the OpenIPC section of my device config:

[...]
# OpenIPC
BR2_OPENIPC_SOC_VENDOR="sigmastar"
BR2_OPENIPC_SOC_MODEL="ssc333"
BR2_OPENIPC_SOC_FAMILY="infinity6b0"
BR2_OPENIPC_VARIANT="ultimate"
BR2_OPENIPC_FLASH_SIZE="16"
BR2_OPENIPC_MAJESTIC="ultimate"
[...]

Majestic Lite works perfectly, but whenever I try compiling an image with majestic Ultimate it fails to start with those errors:

Error loading shared library libmi_ai.so: No such file or directory (needed by majestic)

As you already described some of the mi_*.so libraries are there but with an incorrect name and libcus3a.so, libispalgo.so and libcam_os_wrapper.so are missing.
