[TDA4M] Connector CSI2 Expansion to MIPI Camera

brown son
Intellectual 280 points

Hi.

FPD-Link was not used.

AR0233 module was connected to CSI2 and MIPI-4lanes.

I deleted FPD-link related to iss_sensor_ar0233.c and modified I2C-ID .

I want to know what needs to be changed in the CSI2 code.

I am working on app_single_cam_main.c

Thank you .

    Hi Son,

    Is the sensor directly connected to DPHY lanes i.e. w/o any serializer/de-serializer? If yes, then, please make sure of the following:

    • You need not to do FPD-link related configurations, but you still need to configure the sensor. You can do the same at the same place at which FPD configurations were done earlier. This will make sure of the sequence which needs to be followed.
    • Lane speed configurations shall match on both ends i.e. sensor and TDA4M.
    • Also, please make sure that the channel configurations in the application are matching with the one sent by the camera like resolution and data format.

    Thanks & Regards,

    Hi

    I want to know the Lane configuration of TDA4M.

    I would like to know more details of Lane Configuration

    Sorry to keep bothering you.

     Please explain it in more code level detail.

    Thank you.

    Hi Son,

    By default, 1.5 Gbps is the lane speed configured.

    This default configuration is done in the 'Csirx_initDPhyCfg()' API. If you want to change the lane speed, you can do so after calling this function. 

    After changing the DPHY configs to the desired one, you should call 'IOCTL_CSIRX_SET_DPHY_CONFIG' IOCTL to finally configure lane speed.

    The same can be seen in the 'tivxCaptureCreate()' under the capture node.

    Please refer to the CSI driver API guide for more details.

    Thanks & Regards,

    Vivek Dhande.
