SK-TDA4VM: CSI support of virtual channels

Alexander Schnörch

Part Number: SK-TDA4VM
Other Parts Discussed in Thread: TDA4VM

Tool/software:

Hi all,

my setup looks as follows: I have connected an custom extension board to the csi interface of the TDA4VM. On the extension board are two camera streams deserialized and propagated to the TDA4 using virtual channels. I know it should be in general, but does also the OpenVX framework support virtual channels for csi?

If yes, do you have some documentation you can share?

Best regards,

Alex

    Hi Alex,

    Yes, it does support virtual channels.. In fact, multi-camera example in vision apps uses virtual channels to capture from multiple camera.. You could refer to the OpenVX documentation, especially capture node documentation, to understand how to configure capture node for multiple virtual channels.

    Hi,

    Yes, sure, please refer to multi camera example in ti-processor-sdk-rtos-j721s2-evm-09_02_00_05\vision_apps\apps\basic_demos\app_multi_cam\main.c file. It uses CSIRX module from ti-processor-sdk-rtos-j721s2-evm-09_02_00_05\vision_apps\modules\src\app_capture_module.c file, it configures virtual channel id for each camera in below statement in configure_capture_params API. 

    captureObj->params.chVcNum[vcNum] = ch%4;

    Regards,
