J721EXSOMXEVM: IMX390 not working in Vision Apps

Hi Philipp,

May I know if you are using IMX390 RCM or CM module?

As in the file ${PSDKRA}/imaging/sensor_drv/src/imx390/imx390_serdes_config.h there is a MACRO CAM_MODULE_VER that is 0 for CM camera and 1 for RCM camera based on which the i2c address are different.

In default SDK, the RCM cameras are enabled.

Hence, could you please confirm what is the module present at your end?

Nikhil

Hi Nikhil,

I do not use the RCM or CM module from D3 Engineering. What i use is this: https://www.leopardimaging.com/wp-content/uploads/LI-IMX390-FPDLINKIIII-xxxH_Datasheet.pdf

I changed the I2C address in the imx390_serdes_config.h to 0x84 in order to match the address of our IMX390 sensor.

However nothing changed. There is still the I2C timeout happening.

Hi Philipp,

Could you enable the debug logs in the imaging and please share the same with us?
You could enable the debug logs by #define ENABLE_DEBUG_IMAGING present at ${PSDKRA}/imaging/sensor_drv/src/iss_sensor_priv.h

This would get all the logs present in issLogPrintf() and could give more clarity on the issue.

The UB953 initialization seems to fail too. Where can I set the I2C address of the UB953?
According to the datasheet the UB953 address should be 0x30.

Hi Gang,

we got the information from Leopard Imaging that the sensors I2C address in their datasheet is wrong. However the new one did not work too. I adapted the source code so it tries the whole I2C address range. I get responses from four addresses when reading the chip ID register (0x330) but none of them contains the right value (0x15). Therefore I think our problem is related to this question in the forum: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1049536/tda4vm-single-camera-demo-for-imx390-ub953-question

It seems like the sensor is not powered on and we have to update the serializer settings. 

Thanks for the update!

BTW, do you correct the GPIO value to match the LI camera design?
