I am trying to connect jetson nano and e-Cam30_cunano camera using I2C communication protocol. Jetson nano supports mipi camera signal interface-2 connections. Once in a while, an issue occurs. Camera binding does not take place. To understand what is happening, I took some DSO readings on various pins on the connector.
I am using 2 cameras and connection of one of the camera with jetson nano is shown below:
Observed waveforms are shared as follows:
General observations on this matter:
- I am getting same signals on both CAM_I2C_SDA and CAM_I2C_SCL pins. Its connection is shown below:
- The waveform signal pattern changes after jetson nano gets booted up.
Following questions arise after getting these observations:
- How does jetson nano communicate with this camera?
- What should be the expected signals to be observed on CAM_I2C_SDA and CAM_I2C_SCL pins?
- Why am I observing same kind of waveforms on CAM_I2C_SDA and CAM_I2C_SCL pins?
- What could be some possible causes for this kind of issue?
