Dumping the data in GLBCE link

Hi all,

 I am using DM8127 with IPNC_RDK_V3.00. MT9J003 sensor is  connected & GLBCE is Enabled. I am able to stream the data using RTSP.

Now I want to dump the RAW data in Glbce_Link after GLBCE Algo. copmpletes the processing each frame.

Since that Link is running on M3-VPSS I am not able to do dump it into the file.

My understanding is that, I have to send this data some how to A8(where Linux is running ) and dump to a file.  But not getting the proper way to send data from M3 to A8.

Please help me out in this.

    Ravikiran,

    Please use and connect the IPCFramesIn and IPCFrameOut links on A8 and M3 respectively and have the RAW frame arrive on A8.

    BTW, you just want one frame of data of to be dumped or a sequences of frames to be dumped??

    Hi Venugopala,

                 I want to dump all the RAW frames processed by GLBCE module continuously !!

    Please correct me If I go wrong :)

    •  I will create IPCFramesIn  & IPCFramesOut Links in multichannel_tristream_fullfeature.c 
    • In GLBCE Link I will assign next Link as IPCFramesOut. So the data flow will be
      glbceLink --> IPCFramesOut  --> IPCFramesIn(Host A8)
    • So, I need to do file dump in IPCFramesOut link. 

      Thank you for the help. Will try and update you. Thanks a lot :)

    Hi Venugopala,

                     I am able to create the below path.

                   glbceLink ---->  ipcFramesOutLink -------> ipcFramesILink -->  Dumping Frames {file dump enabled in ti_mcfw_ipcframes.c }

    To check the correctness of data being dumped, I filled 0(zero) in out buffers { glbceLink_drv.c GlbceLink_drvDoGlbceFilter() function}, before putting the processed buffers into the full queue.  (memset(&buff,0,1920*1080*2)

    Now I expect the data dumped in file must contain only Zero's.  But That is not the case!!

    First few words are Zeros(say about 3,609,600 bytes), and remaining part of the file conatins unexpected values!!

    What could be the possible reason ?

    Thanks in advance :)

    Hi Ravikiran,

    Not sure what is causing this. But you can trace along the chain of links which is causing it.
