We analyzed the boot and camera initialization time on the STM32N6570-DK using the DCMIPP SnapshotDecimationMode example (~600 ms boot-to-first-frame) and the Object Detection example (~1 s total). In both cases, the IMX335 camera init dominates boot time (≈480–750 ms). Reducing the reset delay for the sensor (from 200 ms→50 ms) did not improve boot speed — instead the wait time shifted into later stages (e.g. CSI_SetConfig or probe), suggesting the IMX335 requires a minimum readiness time before I²C access.
Our use case only needs snapshot capture (not continuous streaming), so reducing initialization latency is critical. Has anyone optimized IMX335 (or similar sensors) boot time? Are there recommended techniques for quicker camera startup?
