PROCESSOR-SDK-DRA8X-TDA4X: Allowed number of channels in CSITX Node in PSDK6.2

Dipti Natu

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hi,

We are Using PSDK 6.2.0.21.

Our application contains the 4 cameras, and I want to use the CSI2TX node to transmit the data captured by theses cameras.

But while executing our application, we observed following error message.

VX_ZONE_ERROR:[tivxCsitxCreat:719] Object descriptor number of channels exceeds max value allowed by csitx!!!

While digging through this error we found following implementation in file vx_csitx_target.c, in function tivxCsitxCreate() , after looking at following code snippet ,

we found that maximum allowed number of channels are one, as TIVX_CSITX_MAX_CH is defined as (1U)

Query :

1. Can I use CSITX for multiple channel and if yes, how many number of channels are supported by CSITX?

Regard,

Dipti.

Hi Brijesh,

If I want to transmit the 4 channel(camera) data from TDA4, by what means I can do it?

Hi Dipti,

In this case, you need to merge all channels in a single buffer and send it a single channel.. But in this case, receiver should be able to understand this format of the buffer, because even received will get single channel with big buffer.
