    not able to program cy8c20436a

    arun.kumar.4
              Hi,   
         
      I am tyring to use ISSP programming to program CY8C20436A using MiniProg1. For some reason it MiniProg is not recognizing the device. Device is QFN32 pkg soldered on my board. I do not have anything else connected to the micro. I have ohmed out all five lines from micro to the MiniProg(SCK, SDATA, XRES, Gnd, Pwr). All connections are solid. I have tried on mulitple micros and same problem with all micros.   
      I have tried both methods of programming ie (RESET and Power Cycle)   
      Any help would be greatly appreciated.   
         
      Thanks,   
      Arun

               Arun,

                 

               

                 

              I am currently having the same device programming problem, using similar equipment.

                 

               

                 

              Did you manage to resolve this?
