TDA2PXEVM: Read file from SD card and send those data via Ethernet

Hi Gaviraju,

Thanks for your reply.

I generated this use case via generate tool according to this doc<FeatureSpecificUserGuides\VisionSDK_Overview_UsecaseGen.pdf> .

in this document  part "Manually Written Code" , as per my understanding ,I did test code as shown as below :

#include "chains_sdcardfile_Ethernet_priv.h"
#include <src/include/chains_common.h>
static void chain_sdcardfile_Ethernet_SetApp_NullSrcLink(chains_sdcardfile_EthernetObj *pObj)
{
NullSrcLink_CreateParams *pNullSrcPrm = &pObj->NullSourcePrm;
pNullSrcPrm->networkServerPort = 8888;
pNullSrcPrm->dataRxMode = (NullSrcLink_DataRxMode)0;//NETWORK_RX_LINK_DATA_RX_MODE_TCPIP;
pNullSrcPrm->timerPeriodMilliSecs = 1000;
}

static void chain_sdcardfile_Ethernet_SetApp_NetworkTxLink(chains_sdcardfile_EthernetObj *pObj)
{
NetworkTxLink_CreateParams *pNetworkTxPrm = &pObj->NetworkTxPrm;
pNetworkTxPrm->networkServerPort = 9999;
pNetworkTxPrm->transmitDataType = NETWORK_TX_LINK_TRANSMIT_TYPE_TCPIP;
}

void chains_sdcardfile_Ethernet_SetAppPrms(chains_sdcardfile_EthernetObj *pObj, Void *appObj)
{
Vps_printf("AAAAAAAAAAAAAAAAAAAAAAAAAAAA");
chain_sdcardfile_Ethernet_SetApp_NullSrcLink(pObj);
Vps_printf("BBBBBBBBBBBBBBBBBBBBBBBBBBBB");
chain_sdcardfile_Ethernet_SetApp_NetworkTxLink(pObj);
Vps_printf("CCCCCCCCCCCCCCCCCCCCCCCCCCCC");
}

Void chains_sdcardfile_Ethernet(Chains_Ctrl *chainsCfg)
{
chains_sdcardfile_EthernetObj ucObj;
Vps_printf("DDDDDDDDDDDDDDDDDDDDDDDDDDDD");
chains_sdcardfile_Ethernet_Create(&ucObj,&chainsCfg);
Vps_printf("EEEEEEEEEEEEEEEEEEEEEEEEEEEE");
chains_sdcardfile_Ethernet_Start(&ucObj);
while(1)
{
Vps_printf("here here here here here");
}

}

After compiling , it did not work. I think i didn't get the exact way to generate link and chain . 

print messages as bellow('h' is the trigger key) :

Could you help me to understand Link&Chain or show me some support documents exactly?

Thank you very much.
