CCS/CC3220SF-LAUNCHXL: PCB Board UART Communication - Unflash Connect issue

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: CC3220SF, UNIFLASH, CC3200, TPS62163, TPS62162

Tool/software: Code Composer Studio

Hai, 

have a custom designed PCB based on the CC3220SF and i can not communicate uniflash and Debug 

We have not been able to flash our code even once and have not been able to connect it using uniflash to change from production to development mode. 

i followed  www.ti.com/.../swru462 (Design Checklist) ... all are fine 

share my Schematic connection 

  

1.DCDC -ANA2-SW-P ---> 0v

2.DCDC- ANA2-SW-N ---> 0v

3.VDD- ANA2              ----> 0v

but voltage ref (1.6V)

the actual voltage is 1.6 but we are getting 0v

any other change in schematic or resistance value 

TI Schematic File Snapshot 

  

 TI_Board voltage across is fine ( 1.6V) ..

(Design Checklist)---> Followed component is use to pcb board 

   

this components BOM part Number will be used ..

how to solve this issue ..?????

Following Testing voltage Mesurement

Test Point TI Board                   || My Own Board

VIN_IO1                  -> 3.3V             3.3V

VIN_IO2                  -> 3.3V              3.3V

VIN_DCDC_DIG     -> 3.3V              3.3V

VIN_DCDC_PA       -> 3.3V              3.3V

VIN_DCDC_ANA    -> 3.3V               3.3V

DCDC_ANA_SW    -> 1.9V               1.9V

VDD_ANA1             -> 1.9V              1.9V

LDO_IN1                 -> 1.9V              1.9V

LDO_IN2                 -> 1.9V              1.9V

DCDC_PA_OUT     -> 0V                  0V

VDD_PA_IN            -> 0V                  0V

DCDC_DIG_SW     -> 1.2V               1.2V

VDD_DIG1              -> 1.2V               1.2V

VDD_DIG2              -> 1.2V               1.2V

DCDC_ANA2_SW_P -> 1.6V             0V ( issue point)

DCDC_ANA2_SW_N -> 1.6V             0V ( issue point)

VDD_ANA2                -> 3.2V             0V ( issue point)

VDD_RAN                  -> 1.2V             1.2V

VDD_PLL                   -> 0V                  0V

Any other solution at this issue--> how to power up the board , uniflash also not connect..

Thanks
