    how to program CY8C4245LQI483 by cy8ckit-042


      Hi , i build device (project found at internet ) with CY8C4245LQI-483 . I assembled device and try to program by CY8CKIT-042 , this kit contains SWD programmer to program internal CY8C4245AXI-483 , i disconnect built in procesor by removing R34, R32 , R33 , and i connected SWDIO ( instead R32 ) SWDCLK( instead R33) and reset (instead R34) , also i connected Vdd and GND , programmer works with built in processor , and do not work with external processor , i have ERROR

      "FAILED! Timeout of SROM polling. Lost communication with chip" . What is wrong ? , i have only HEX file for my project , should i have any additional file to configuration ?

      Maybe will it works with lower SWD clock speed , but in my kit is only 1.6MHz and is not changeable ( inactive) .
