Using Camera without I2C

[patrickwiegand]

Hello,

i have a Nitrogen6q (i.mx6 quad) board with Ubuntu (or Yocto) running and want to connect a camera to it. This camera has no I2C bus Connection. Now i am wondering how the camera could be recognized by  the OS and with what kind of software the Images can be handled. The camera is connectet to the parallel camera port with a 17-bit interface (14bit Pixel data + pixel_clk + line/frame_valid) and can be configured via RS-232.

Regards,

Patrick

Hi Patrick

new camera integration steps are quite well described in

i.MX53 System Development User’s Guide (rev.1, 3/2011)

Chapter 19 Supporting the i.MX53 Camera Sensor Interface CSI0,

though for older kernel. One can try to change i2c control channel to uart.

For i.MX6 IPU connections and supported formats one can look at

Table 66. Camera Input Signal Cross Reference, Format, and Bits Per Cycle

i.MX6DQ Datasheet (rev.4, 7/2015)

Best regards
