SOLVED 307 MCLK dtb setting
-
Hi I am working with the veye cs mipi 307 camera module. I am trying to use the camera module with a custom carrier board instead of the dev kit with jetson nano.
the camera module works fine with the jetson nano dev kit, but its not working with our custom carrier board. I was looking at the datasheet for the imx307 and comparing with the dtb and driver that veye has on the github repo. My question is:
- Do you have a clock generator chip on the cs_mipi_imx307 module ? The datasheet mentions clock should be either 37.125 or 74.25 MHZ but jetson nano can only do 24 MHz and veye dtb has mclk=24Mhz.
- In the veye i2c driver, you are writing to register addresses that are different from the datasheet, do you have another chip on board that is handling the i2c comms ? which means we do not have raw access to the i2c pins on the imx307 ?
Also is it possible for you to share the schematic of the 307 module ? would be helpful in debugging our issues.

The camera itself has a clock, so it does not require a clock signal from the motherboard.

The module itself comes with an isp module, and the output data format is YUV. you can't access the sensor directly.

Sorry, I can't fully disclose our schematics. You can refer to the datasheet on wiki.veye.cc.
