TDA4VEN-Q1: Adding new image sensor to Linux

bing zhu
Intellectual 360 points
Part Number: TDA4VEN-Q1

Tool/software:

Hi, experts

On the TDA4VEN we used your serial deserialiser solution for getting data from the camera, the data flow is as follows:

OVX1F(x4) --> DS90UB933 --> DS90UB960 --> TDA4VEN(CSIRX).

I've successfully lit the camera on main2_0 before, and now I want to light it on the A core.

I refer to this link 3.2.2.3. CSI2RX — Processor SDK J722S Documentation，but I don't find the /dev/videoX node under TI-CSI2RX, can you provide a specific guide for me to refer to, thanks!

root@j722s-evm:~# v4l2-ctl --list-devices
TI-CSI2RX (platform:30102000.ticsi2rx):
	/dev/media0

TI-CSI2RX (platform:30122000.ticsi2rx):
	/dev/media1

wave5-dec (platform:30210000.video-codec):
	/dev/video0
	/dev/video1

e5010 (platform:fd20000.e5010):
	/dev/video2

board: custom board

sdk: 10_00_00_08

    Hi Bing,

    This is not a sensor is that is supported out of box. Please share all the steps you've taken up to this point to enable this sensor and share the output of media-ctl -p?

    Please go through the following FAQ and let me know if you have any further questions: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1403223/faq-most-common-problems-encountered-when-developing-camera-applications-on-the-am6x

    Thank you,

    Fabiana

    I haven't changed the sensor, deserialiser and serialiser driver matching yet.
