iMX8 Second CSI Interface

Technical Support

Hi,
I currently use the Apalis iMX8 QuadMax 4GB IT with Ixora V1.1 carrier board. I want to design a custom carrier board based on Ixora. Ixora only has a CSI bus but in Apalis iMX8 datasheet there is a second CSI bus.

  1. Is the second CSI bus enable in latest BSP?
  2. Can I use the second CSI without any change in BSP?

Thanks.

Hi @prog

MIPI CSI is disabled by default. However, you can enable it in the devicetree by doing something like:

mipi_csi_0 {
    status = "okay";
};

mipi_csi_1 {
    status = "okay";
};

But you also have to add a camera driver there. Check imx8qm-mek.dts « freescale « dts « boot « arm64 « arch - linux-toradex.git - Linux kernel for Apalis, Colibri and Verdin modules for example. Search for mipi_csi_0.

Stefan
