Worth a retest on a current nightly. Image orientation handling on SigmaStar has changed since this report — flip/mirror is applied through the sensor path and is now reapplied live on a config reload, rather than only at startup.
Could you grab a recent nightly, confirm the version with
majestic --version, setimage.flip(orimage.mirror) and reload, and let us know whether the picture flips? If it still doesn't, please attach the log around the reload and yourmajestic.yaml— that'll tell us whether the sensor is rejecting the orientation or something else is in the way.widgetii commentedon Oct 4, 2026
The mirror and flip settings are lost inside the SC3335 sensor driver for infinity6b0, which resets the sensor to unflipped every time it initialises, so the setting cannot survive a restart. That driver (from OpenIPC/sensors) is built and shipped by the firmware, so this is moving to OpenIPC/firmware. Separately, your
isp.sensorConfigpoints atsc401ai.binwhile the sensor is an SC3335; leaving it unset lets the matching tuning file load.openipc-ai commentedon Oct 26, 2026
The fix is in OpenIPC/sensors#8. The driver applied the orientation you asked for and then reset it at init, so a flip or mirror set in
majestic.yamlwas lost every time majestic started. A change made while it was running did reach the sensor, but didn't survive a restart.We have no SC3335 board, so it was verified on an SSC335 with an SC2336, whose driver had the identical bug. After a restart the sensor's orientation register stayed at
0with the old driver for every setting. With the fixed driver it is0x66,0x60,0x6or0, depending on the setting.Firmware builds pick up the sensors repository's latest commit, so the fix will be in the first nightly after that PR merges. @arcidodo, if you can flash that nightly and confirm the picture flips on your C110 after a reboot, that's the SC3335 test we can't do here. Also leave
isp.sensorConfigunset (it currently points atsc401ai.bin).sigmastar: sc3335, sc2336: record the orientation pCus_SetOrien was a…
openipc-ai commentedon Oct 26, 2026
OpenIPC/sensors#8 is merged, so the next nightly carries the fix. @arcidodo, a flip or mirror set in
majestic.yamlshould now survive a reboot on your C110. A report either way, withmajestic --version, would confirm it on the SC3335 itself, which we can't test here.
