Firmware research and on-camera tools for the SIGMA fp.
Everything here runs from AutoRun.txt on the SD card, in RAM only —
remove the file, power-cycle, and the camera is stock. Nothing is written to flash.
Firmware Ver.5.02 only.
| product | version | what it does |
|---|---|---|
| fpsup-gyro | v1.11b | writes Gyroflow's .gcsv and .json while recording |
| fpsup-og3k | v0.1.1test | 3:2 open gate, 3024×2010, eight frame rates — sensor modes 98/117, a native 2×2-binned readout rather than 6K resampled down. Records correctly at every ISO: v0.1.1test fixes the conversion-gain misclassification that cost 2.7 stops of highlight headroom above ISO 640. |
| fpsup-usbshell | v3.1.0 | the shell that answers shl over USB |
Each release is two files. Copy AutoRun.txt and
VSHL.BIN to the root of the card — no folder to make, no step afterwards.
To combine two of them, use the card composer rather than copying both.
