    Connection between the chip and the KIT

    zax.lee

      Hello everyone~

         

      I got problems on connecting with the chips and the KIT.

         

      The chip that I use is "CY8C3866AXI-040",and the KIT is "MiniProg3".

         

      I did not buy the develop board ,so I created it by myself.

         

      The problem is while I using the PSoC Programmer to program the chip,and it shows "Can not acquire SWD device!".

         

      I think I do wrong in the pins connection.

         

      These are the pins I connect according to the datasheet.

      KIT(TDI)---Chip(Pin23)

      KIT(VTARG)---Chip(Pin26)

         
         
          

       

         
         
          

      KIT(GND)---Chip(Pin14,38,64,87)

          

       

          

      Should I  add  capacitances or  resistances to make the  circuit correct?

          

      I have been trapped for a long time.

          

      Thanks a lot
