TDA4VE-Q1: serdes camera bringup

Kim Semin

Prodigy 170 points

Part Number: TDA4VE-Q1

Tool/software:

I use a custom board and the SDK version is 8.6.

I want to bring up a new camera using maxims serdes.

I can i2c communicate with deserializer, but communication with serializer and image sensor is not possible.

So the question is

1. I'm currently using the GMSL connection method, but whether this board supports the GMSL method

2. Previously, I communicated with other cameras through the FPD link method on the board, and I changed only the i2c and register addresses from that code to that camera,

but whether the difference in transmission method is the cause

3. If that's the case, how to solve it

Thank you

Hi,

The SDK does not support GMSL out of the box. It only supports FPD Link.

You would have to check with the GMSL SER DES vendor regarding this.

Regards,

Nikhil

The camera I wanted to bring up also supported fpd link, so I connected it in that way, but there was a problem.

i2c comunication with deserializer and serializer was successful, but after that, communication with the image sensor is not possible.

I confirmed that the camera works well on other platforms, and I also checked the i2c address of the image sensor,

but I don't know which part is the problem.

Hi,

Have you followed below developer note for adding a new image sensor to the image framework?

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos/docs/user_guide/developer_notes_image_sensor.html

Regards,

Hi Kim,

Kim Semin said:
i2c comunication with deserializer and serializer was successful, but after that, communication with the image sensor is not possible.

I confirmed that the camera works well on other platforms, and I also checked the i2c address of the image sensor,

Are you able to read/write sensor registers via CCS or i2c tools (looks like you can do that for SerDes already)?

Copying my friend Brandon Maciel for his comments.

Thank you for your suggestion.

I followed the developer note guide well.

Also, I communicated with serdes through i2c write, and the sensor side failed.

So I wonder if there is a register among the serializer register setting values that allows communication with the image sensor or whether i2c communication is possible regardless

Also, have you seen other cases where only the image sensor can't communicate

Thank you

We are not familiar with GMSL SerDes.
Brandon Maciel can share his experience with FPDLink.
Typically, it is something related to configuring sensor clock/power input, and i2c address.

Hi Kim,

Can you confirm that the serializer is programmed properly for clock out speed and GPIO pins?

Some sensor modules may require specific GPIO pins to be pulled high or low to allow read/write over I2C.

I have also seen some camera modules carry I2C bus switches that need to be programmed before R/W over I2C is allowed. You may check if there is extra hardware needing to be programmed

Thank you for your advice. I'm trying the method you told me, but if the sensor and the i2c bus of serdes are different, can I change the i2cinst value arbitrarily at the sensor side i2c write or is there another way

0 Brandon Maciel over 1 year ago in reply to Kim Semin

TI__Prodigy 496 points

Hi Kim,

In our HW/SW platform, the SerDes and Sensor are connected to the same I2C bus. In the individual driver IssSensor_CreateParams data structure, i2cInstId is not used by any of the drivers. The I2C bus is pulled dynamically with IssSensor_getDeserializerI2cAddr

Hello, while continuing to bring up, the camera vendor said that there is a soc inside the camera, so there is no need to set the sensor, just set the serdes.

So I finished setting the serdes, but an error occurs in the capture part such as log.

When do singlecams get an error such as log?

Also, do I need additional settings in imaging to bring up the camera with soc inside?

Thank you

Hi Kim,

This is just a warning for not providing an error frame for capture node.
It shall not cause any issue for capturing from sensor.

It looks like your sensor did not start streaming.

Hello, I am currently struggling with the same camera.

but when I asked the vendor, I heard that the camera works without the sensor setting as long as you set the serdes.

Among imaging, the is_sensor_gw_ar0233 sensor seems to be similar to my sensor right now.

Is there anything that can help my current situation in the process of operating and displaying the camera during the sensor's serdes setting process

Thank you

Hi Kim,

In general, the capture node and serdes must be configured and started before the sensor starts streaming.

The camera worked when I fixed the band speed setting and gpio pin setting connected to the sensor trigger in the serializer. Thank you for your help
