I wrote the imx307 sensor driver and dts myself. It’s i2c communication is ok.
But when I run sample program：
[INFO] (NvEglRenderer.cpp:110) Setting Screen width 640 height 480
PRODUCER: Creating output stream
PRODUCER: Launching consumer thread
CONSUMER: Waiting until producer is connected…
CONSUMER: Waiting until producer is connected…
PRODUCER: Available Sensor modes :
PRODUCER: [0] W=1920 H=1080
PRODUCER: Starting repeat capture requests.
CONSUMER: Producer has connected; continuing.
CONSUMER: Producer has connected; continuing.
Then the kernel crashed：
