LT3471 Out of order

I am a new hand, the new welded circuit board, can not work normally, to consult.
Solder circuit board according to chip manual.However, Vref is always 0.56v, the chip cannot work, the positive voltage output is wrong, and the negative voltage cannot be output.Use STM32 pin pull-up to output high level to soft start pin SS1/SS2.
