Ticket Name: RTOS/TDA2: Code example for reading and saving CSI-2 data in TDA2x

Query Text:
Part Number: TDA2 Other Parts Discussed in Thread: AWR1243 Tool/software: TI-RTOS Hello, I am new to designing the ADAS solutions using TDA2x board. I want to integrate 4 cascaded radar sensors with my TDA-2 processor for my application. I read few posts on TI's website which mentions about using DS90UB960 Deserializer Hub which receives 4 inputs and transmits into one (or two) CSI-2 output port. This interleaved data is then set to TDA2 processor. Is there any example code on how to decode this interleaved data on the TDA2 processor end and store it somewhere( maybe in SD card or PC) so that I can use this CSI-2 data to perform few radar algorithms? Thank you!

Responses:
Hi Nishant, TDA2x dosen't have CSI2, The CAL driver (hw) performs the de-interleaving. Please refer any of the SRV demos. Regards, Sujith

Thank you Sujith! I shall look into it and get back to you if I have any questions. Do you have the link for the SRV demos? Best Regards, Nishant

Hello Sujith, Referring to the answer given by Piyali to this post: https://e2e.ti.com/support/arm/automotive_processors/f/1021/t/662898, where can I find the "single AWR 4 Rx 3Tx de-interleaving done by the EVE FFT functions on the TDA " reference document? I tried searching online but I couldn't find it. Also could you mention the best sources for reading more about the Camera Adaptation Layer (CAL) drivers? Best Regards, Nishant

Hi Nishant, For CAL details, can i ask you to refer the TRM (Data Manual) of TDA2Px or TDA3x. For the demo applications please refer \apps\src\rtos\usecases\iss_mult_capture_isp_dewarp_3dsv_tda3xx I will have to check on the AWR and get back to you. Regards, Sujith

Hello Sujith, Thank you for providing the file location for understanding CAL implementation. I have a related question to my original question I asked before, can CSI-2 data be read directly by the TDA3 processor? In Fig 2.7 of the "ProcessorSDKRadar_UserGuide.pdf", there is an image where the CSI-2 Data from AWR1243 is directly connected to TDA3X. I had asked my local TI engineer for help in designing the hardware for the connection board (DIB+VAB boards) for interfacing AWR1243 with TDA3 and she asked me to refer fig 2.7 to create my own customized board for it. So do we need CAL driver hardware only for TDA2 or does TDA3 also require it for collecting data from various sensors? Thank you, Nishant

Hi Nishant, TDA2x dosen't come with a CSI2 receiver. Only TDA2Px, TDA2Ex and TDA3x has this hardware. Regards, Sujith

Thank you! Best Regards, Nishant
