CCS/CC256XEM-RD: Strange behaviour of CTS and RTS pins of MSP432+CC2564

Part Number: CC256XEM-RD
Other Parts Discussed in Thread: CC2564, CC256XQFNEM, CC2564C

Tool/software: Code Composer Studio


I am new in low energy bluetooth so i am sorry if i make a stupid question and my bad English. I have problems with CC2564xEM module in starting process. I use MSP-EXP432P401R board to connect to CC2564xEM (without adapter board). i config Pin P4.2 of MSP432 board to output pin to use ACLK (32.768KHz) by using Code composer Studio like this : 

I used Bluetooth Stack v4.2.1.0 so i connect MSP-EXP432P401R with CC2564xEM like this (in Hardware configuration ):

But in the start up process i get an error like this : 

i did not change any Jumper on both MSP432 and CC2564xEM also. Using oscilloscope to check the signals, i saw the 32KHz clock is stable 8ms before nSHUTD signal rise up(High state). The 26MHz clock worked. But after that the RTS signal is always high. Could you guys tell me what is my problem here?

Thanks in advance.
