RTOS/TDA2P-ACD: Flow of data before ISS Capture link

Part Number: TDA2P-ACD

Tool/software: TI-RTOS

HI All,

We want to know how the iss capture link gets the SYS_NEW_CMD_DATA ?

We know that in ISS capture task file, IssCaptureLink_drvProcessData() function is registered as a callback for new data received to ISS capture link. Who notifies the iss capture link for new data ?

What is the flow from the CSI2PHY to ISS Capture link for a frame that is captured ?

Regards,

Deepika,

NEW_DATA command is sent from the driver frame captured callback.. When frame is captured and available, it sends this callback, from this callback, NEW_DATA command is sent to the capture link itself.

Hi Brijesh,
Thank you for the reply.
Could you please elaborate more. Also please let us know where to check for the driver in ti_components Processor SDK 03.05 ?

Deepika,

Please refer to TRM one more details about CSI2PHY to memory link. There is a CAL/capture module, which captures frame data into memory.
Driver just gives the callback when entire frame is captured..

Brijesh ,

Thanks for the reply. One more doubt,does this memory copy uses EDMA ?

Deepika,

no CAL has internal DMA. It does not use EDMA..
