      hello guys,

         

      i made a custom pcb using 

         

      psoc4 CY8C4245LQI-483 ,

         

      i manufactured 4 PCBs - i am trying to program with miniprog3 

         

      in 3 of my custom circuits  i get the following error :

         

      " Unable to acquire target device..." 

         

      1 of my custom circuits seems to work flawlessly i can program it , debug , control gpio .

         

      after double checking my schematic i saw an error , i accidently routed the  VCCD pin to 3.3v instead of  

         

      connecting it to gnd (image of how i connected power is attached) , 

         

      do you think this error is a critical design error ???  (i saw some desgins where u can connect it to 1.8v)

         

      do you think this might be the problem ??
