编译器/ TDA4VM：How to use CSI TX as application output

jingyu.zhang

Part Number: TDA4VM

Tool/software: TI C / C ++编译器

Hello, Ti

I noticed that the DSS in the current SDK 7.1 version can only support DSI, EDP and HDMI. And I want to use CSI TX as the output of the application to send the captured video.

Whether I need to write my own code in the application to complete the sending of CSI TX, and whether there are ready-made reference codes in the SDK.

Hi Zhang,

We do have some examples in the SDK, but not in the usecase. You could refer to this example and develop the application.

You could find this example in ti-processor-sdk-rtos-j721e-evm-07_01_00_11\tiovx\kernels_j7\hwa\test\test_csitx_csirx.c file.

Hi Brijesh

Thank you for your reply. The example you mentioned describes how the application calls csitx to send data. We will try to modify the application。

By the way, The data flow of CSI Rx steam1 in TRM is directly transferred from csirx to csitx .

I found that the current camera sample uses CSI Rx steam0. Can I copy steam0 to steam1 by configuring CSI register? If so, how can I configure it.

Regards,

Zhang

Hi Zhang,

No, this path (CSIRX to CSITX via stream0) is not supported..

Hi JY,

Please find this doc item i2052

This path is not available on TDA4VM. You need to go to DDR.

Thanks & Best Regards!
