TDA4VM: How to enable csi ECC function

Hi Michael,

Which CSI ECC module do you mean here? Is it ECC on CSI header?

Brijesh

Hi Brijesh，

We need to protect the data transmitted by DSI through ECC. But I don't know whether this function is supported.

I found DSI_ECC_AGGR_ENABLE_CLR similar to the function in TRM12.6.5.2.1.14.

It seems that have a document named TDA4VM Safety Manual about the function. Could you please share the way to get it?

Regards,

Michael

Hi Michael,

Do you mean DSI or CSIRX? Those two are difference modules on TDA4VM.

Please contact local TI support for getting access to Safety Manual.

Hi Brijesh，

Yes, how to enable it?

Hi Michael,

Could you please clarify if you are looking for enabling ECC for MIPI DPHY or CSIRX?
Which one is it?

Hi Nikhil，

I am sorry for being misunderstood. We need to enable these two functions.

Hi Michael,

Currently the ECC for the CSI header is already available at the driver level and you could get the error count via the capture node stats.

Could you let me know if this is what you are looking for?

Hi Nikhil,

Where can we find  sample code in in ti-processor-sdk-rtos-j7-evm-07_03_00_05?

Which register is related to the capture node stats？

Regards,

Michael

Hi Michael,

This is part of the capture node.
You could get the information about the ecc stats or other stats from the capture driver using tivxNodeSendCommand() with IOCTL TIVX_CAPTURE_GET_STATISTICS from your application.

This implementation can be found in tivxCaptureControl() in tiovx/kernels_j7/hwa/capture/vx_capture_target.c.

Hi Nikhil，

Thank you for your support. I'll try it.
