edgeai-vision-aen

End-to-end EdgeAI reference application for the E1M EVK populated with an E1M-AEN701 SoM (Alif Ensemble E7).

   Camera (e.g. OV5640)  →  ISP / format convert  →  Ethos-U55 inference  →  SSD1306 OLED overlay

Source: examples/aen/edgeai-vision-aen/.

Status​

VersionStatusWhat works
v0.1skeletonCompiles under native_sim/native/64 and on the EVK once the AEN board file lands. Init flow is real (I²C, OLED, IMU); camera + Ethos-U inference are stubbed.
v0.2targetReal OV5640 capture via <alp/camera.h>, Vela-compiled MobileNetV2 inference on Ethos-U55-HP, results overlay on OLED. Acceptance bar: ≥ 10 fps.

# Host smoke test

The v0.1 build prints which SDK pieces it successfully initialised and which v0.2 stubs it skipped.
