    program PSoC 4 with external microcontroller

    zamroodhh_1690331

      Hi,

         

      I am using a kinetis K64 MCU to program my CY8C4245AXI-483 PSoC.

         

      I am refering the below link

         

      http://www.cypress.com/documentation/application-notes/an84858-psoc-4-programming-using-external-microcontroller-hssp

         

      I ported the code to suit the K64 IC and the program seems acquire the device and i get the IDCODE right. But it fails in the check silicon ID step.

         

      The last bit(31st bit) in the CPUSS_SYSREQ register is not being deasserted. from what i have saw from the data sheet, this bit will get deasserted automatically after the system call happens. Here in my case what could be the problem ?

         

      Anybody please help
