TMS570LS3137: (SCI communication) Missing data when using sciReceive function.

Hi,

I have two Hercules TMDS570LS31HDK Launchpad. My main goal is receiving data from Hercules 1 in Hercules 2. 
Our data looks like Fig.1.


Fig.1. Sending Data (Correct)


Fig.2. Receiving Data (Incorrect)

I do not observe any problems while sending the data, but when I want to receive the data with Hercules 2, I noticed that some bytes are missing. (Seen in Fig.2.)
My experimental setup is as follows: When the GIOA7 button on Hercules 1 is pressed, data is sent from Hercules 1 to Hercules 2. Hercules 2 runs the code in the code snippet below.

    uint8 packageData[100];
    uint32 receivingSecondByteData;
    int byteNo;
    while(1){
      receivingSecondByteData = 0;
      byteNo = 0;
      while(receivingSecondByteData != 0x16)
      {
        receivingSecondByteData = sciReceiveByte(scilinREG);
        packageData[byteNo] = receivingSecondByteData;
        byteNo++;
      }
      
      for(int i=0; i< 10000000; i++){} 
      if(byteNo != 0){
        vSciDisplayText(scilinREG, &packageData[0], byteNo);
      }   
      for(int i=0; i< 10000000; i++){} 
    }

I don't understand why I am not getting the data properly. 

Thanks for help, Regards.
