Notify example problem on evm6678



I Want to use 6678 Notify example in CCS in one Image and Run it in MAD through tftp. It seems works ok.

Then I add EVM_init function in xdc startup function. The EVM_init function can be found in MCSDK Image example. And init Serial port on Core0 in task_fun0 function. Then it can work correctly thourgh CCS jtag mode. I can see serial output in serial console.

 But when  I use it through tftp Using MAD.   The serial output shows that the Notify interrupt can't  any more message. I try to remove evm_init in xdc startup function and add it in tast_fun0. The notify example works ok again.

I can't understand why?

I do the same actions in messageQ example, the serial console output right and the messagQ works ok.
