Linux/TDA2PXEVM: NULL_LINK_COPY_TYPE_FILE of NullLink is NOT working

Part Number:TDA2PXEVM

Tool/software: Linux

Hi,

I'm developing the usecase of reading bayer data from file and processing iss/simcop and yuv file saving.
The reading bayer, iss/simcop and display to HDMI are ok.

But file saving is not working, the file size (bufList.buffers[0]->payloadSize) at NullLink_drvProcessFrames() is just 72bytes not 3MB for FHD image.

Please refer to the following usecase txt.

UseCase: chains_raw2yuv_conversion (Linux)
NullSource (A15) -> IssM2mIsp -> IssM2mSimcop -> Dup -> Display_Video
IssM2mIsp -> Alg_IssAewb
GrpxSrc -> Display_Grpx
Dup -> Null (A15)

Regards,
HJ Kim
