Compiler/AWR1443: can

Tool/software: TI C/C++ Compiler

Hi,

I want send data to two boards awr1642 from awr1443 DCAN.  below is the code. 

Second tx ID is not working.  

Two data are transmitting to the one board.  data might be over riding in RAM.  If I change the DCAN_TX_MSG_OBJ , the program is terminating. 

I am not understanding where the mistake is . please can you go through the below code and guide me.
