TIDA-00663: Calibration function in TIDA-00663

 Hello,

I had design a product according to the TIDA 00663.And now I'm debugging the calibration function.However,when I give TPS22968 the start signal,and it do output the  3.3V VOUT at the rate of 3.3V/120us,but I could not detect the pulse signal at the position of R5 or R6,let alone between C8 and C10.Is there anything I mistake?
