AML-A311D-CC and cameras

Hello,

I’m looking for a platform where I can connect a camera sensor on MIPI CSI but I need to generate a clock in range [6-27]MHz to the 18th pin of the camera connector (CSI_CLKBP). On schematics I found it was connected to the PWMAO_D of the A311D SoC, but I’m unsure about its capabilities. I couldn’t find additional information in the software stack sources.

Is it possible to modify the device tree in order to generate a valid clock for such camera ?

Edit: Figured out that A311D CSI ISP is not currently supported, but I’m not sure it’s a real problem ?

Cheers,
Simon

Normaly, we don’t need ISP functionalities but… Can we still grab frames ?

In order to get an camera to work, you need the following chain:

  1. Generate proper clocks either via PWM or a clock generator. For many sensors, this is unnecessary.
  2. MIPI CSI support (this is not yet available on upstream kernel). This is probably your blocker.
  3. ISP if the sensor does not provide YUV output.
