TDA2EVM5777: Couldn't establish I2C connection with OV10635

Subramaniyan Alagappan

Part Number: TDA2EVM5777

Hi,

I am trying to connect OV10635 camera through 913/914 deserializer-serializer in the Multi-des daughter board of TDA2x EVM. On my trial, I couldn't find the v4l device or i2c device of the camera at the specified address in ARM core.

Here are the details of my work:

Board : TDA2x EVM5777G-03-40-00 + Daughter board

OS: Linux in ARM - yocto 6.00.00.03 built

Steps I followed:

1) Connected OV10635 camera in the multi-des board, which was already mounted on vision board

Pic 1: Cam connection on multi-des board

Pic 2: Camera side connection and pin settings

2) Set the SW3 in the vision board to 01010101, as mentioned in https://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Automotive_Software_Developers_Guide#Capturing_from_OV10635_Vision_board_camera

3) Restarted the board and probed at bus 1, address 0x30 to identify the camera, but device not detected at 0x30

4) Deserializer was identified at bus 1 address 0x60 and I was able to read and write the DES registers

#i2cdetect -ry 1 => yielded devices at addresses 0x1b, 0x21, 0x25, 0x27, 0x50, 0x60, 0x61, 0x64, 0x68, 0x69, 0x6c

60: 60 61 -- -- 64 -- -- -- 68 69 -- -- 6c -- -- --
70: -- -- -- -- -- -- -- --

5) Configuring DES registers as per the 914 datasheet to communicate with SER,

a) Read DES register SER ID (0x06) and found the value 0xb0, which is device id of serializer 913

b) Found the register SER ALIAS (0x07) with default value of 0x00, and set that with 0xb2 value

c) Enabled pass-through by setting the value of register I2C CONTROL 1 (0x21) to 0x97 from 0x17

d) I2C read of serializer address failed

#omapconf i2c read 1 0x58 0x00 => i2c read failed

6) Ran BIST test by tweaking the BIST CONTROL register(0x24) and found there were no errors on the PARITY ERROR COUNT register (0x25)

Kindly help me on how to communicate with the serializer and then with camera.

Subramaniyan,

Could you share your you kernel log file?

You may also get some information about driver dts configuration in below thread:

Hi Jian,

I have attached the kernel log here for reference. We had a some hardware debugging sessions and we found that there is no proper communication between the EVM board and 913 Serializer via 914 deserializer.

Coming to the kernel messages, under the driver ov1063x.ko we get the following error

ov1063x: probe of 1-0037 failed with error -121

I am suspecting the error id 121, may come from I2C connection timeout error 121.

I am not seeing any V4L device after connecting the camera. Kindly let me know where should I look for DTS configuration.

Note:

I have initiated another thread on the interface forum about 913/914

Subramaniyan,

I saw you are focusing on I2C debug on the other thread. I will mark this thread as closed.

Please reopen or create a new thread (if the nature of issues is different).

regards

Jian

Hi Jian,

I would like to reopen the issue, as in the interface forum (), they have suggested that I2C signals, locking of serializer and deserializer is proper and the issue may be with Processor SW.

As I mentioned before the I am having Linux OS in ARM of TDA2x5777EVM built from yocto 6.00.00.03. I don't know why I couldn't see the serializer in the I2C bus or OV10635 camera in the /dev/ location. Kindly help me to solve this issue.

Regards,

Subramaniyan

Subramaniyan,

just to confirm, there was no changes from the OV1063x probing during boot, all logs stays the same?

>>> Kindly let me know where should I look for DTS configuration.

sdk/board-support/linux-4.19.94+gitAUTOINC+5a23bc00e0-g5a23bc00e0/arch/arm/boot/dts/ti/

you would see files named by board names. for OV device, you need to set both camera driver and associated i2c driver. i will also check with my colleague who are familiar with the device.
