TDA4VM: TDA4VM EDGE AI Board operating with DS90UB964-Q1EVMTDA

Hi Jeff,

As a disclaimer, on the SK-TDA4VM we do not support the RTOS capture drivers as documented here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/08_04_00/exports/docs/faq.html. If you replace the driver for DS90UB960 in RTOS SDK, you will still not be able to run any of the Edge AI demos since they use the Linux driver, and no testing or validation for the vision_apps demo has been done with SK-TDA4VM, so we cannot promise that all the demos will work even with the correct drivers in RTOS SDK.

My recommendation is to buy the larger EVM board when running vision_apps demo: https://www.ti.com/tool/J721EXSOMXEVM

If you are planning to run the Edge AI demos, I can share the patches applied to the Linux SDK for IMX390 camera with DS90UB960 that you can reference:

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/imx390_2D00_fpdlink.patch

Hi Fujiwara,

Appreciating for you work and reply, we have the larger EVM board either. It is crucial for us to evaluate the vision_apps demos, since the surround view demos are what we need.

It is worth to notice that the DS90UB964-Q1EVMTDA is the FPDlink developing kit we are using now instead of the DS90UB960.

Because the the Fusion1 Rev C board used in the RTOS demo is no longer manufactured.

Therefore, in such sinario, we have no choice but to replace the FPD driver to DS90UB964, so please indicate the instruction to fulfill this switch.

Regards,

Jeff

Hi Jeff,

If you are using EVM and planning to run some vision apps demos, then you need to make changes for ub964 in ti-processor-sdk-rtos-j721e-evm-08_04_00_02\imaging\sensor_drv\src\iss_sensors.c and ti-processor-sdk-rtos-j721e-evm-08_04_00_02\imaging\sensor_drv\src\imx390\iss_sensor_imx390.c files. These two files configure ub960 deserializer available on Fusion board.

Do you happen to have settings for ub964? 

Regards,

Brijesh

Hi Brijesh,

No, I have zero experience setting up a UB964 deserializer. Professional assistance will be helpfully moving forward.

Jeff

Hi jeff,

I would suggest moving this ticket to our SERDES team.

Brijesh

Hi Brijesh,

Is there a script from the 960 that was being used for setup. I can use that to see how the 960 is being setup and then see what we can do on the 964.

Glenn 

Also please note that 964 can only be compatible with DS90UB913AQ/913Q/933Q Serializers

Glenn 

Hi Glenn，

The cameras we now have are the imx390 with DS90UB953, is it suitable?

Regards,

Jeff

Hi Glenn,

ok, I will replace the serializers with the DS90UB913AQ/913Q/933Q for those IMX390. Please show me the method to set up the 964 on the EVM.

Regards, 

Jeff

HI Jeff,

The 913A and the 953 are not pin compatible. Did you rework the board to match the 913A pin signals?

Hi Glenn,

Yes, two options will be developed at the same time,

1. fab another board using the 913A matching with the imx390;

2. is any other development board like DS90UB964-Q1EVMTDA but using 960 chip ?

Regards,

Jeff

Brijesh,

Do you have any other development board that has 960 device?

Glenn 

Hi Glenn,

is it suitable for the larger EVM board and the camera using a 935 Serializer?

Regards,

Jeff

Hi Jeff,

Don't understand your question. This would be an EVM for the 960 and you can connect cameras to it. 

Please see the user guide to determine if this would work for your need.

Hi Glenn,

I mean that this DS90UB960-Q1EVM  can connect the cameras which are using the 935 Serializer and the large TDA4 EVM board shown below, right?

Regards,

Jeff

Jeff,

I am not familiar with the capabilities of the TDA4 EVM.  Also maybe you can just remove the 960 unit off the EVM and put it onto the TDA4 EVM. 

Brijesh Jadav

Brijesh, 

Do you know if we connect the 960 EVM to the TDA4 EVM?

Glenn 

Hi Glenn & Brijesh,

Is there any update about this?

Regards,

Jeff

Hi Glenn,

As such, it looks like UB960 EVM also outputs on similar mipi connector as supported on EVM, but we have not really tested/validated this EVM in SDK. so can't say if this will work as it is with EVM.

Regards,

Brijesh

Brijesh,

I believe the best solution for Jeff is to get an 960 EVM and demount that unit then put onto the TDA4VM. 

Do you see any issues with this?

Glenn 

Hi Glenn Uranga,

Yes, can try connecting directly. I am not sure how this board accepts power support. It might be from external power supply.

On Fusion board, this is provided from the EVM.

Also please check with the sensor and see what LVDS power supply required. For IMX390, we are using 12V on Fusion board..

Regards,

Brijesh 

Hi Brijesh,

I checked the camera power supply required, ranging from 5 - 16V.

Regards,

Jeff

Hi Jeff,

Please check if UB964 EVM has some jumper to select LVDS power supply. If i remember, it used to support two options 5V and 12V. Please select the jumper settings as required by camera/serializer.

Brijesh
