  • hello,

    i am programming STM32F Series and MC908GP32 very well using cyclone universal.
    recently, added new controller named mk20dn512vll model and used new products
    so i made created image. inserted filed to cyclone universal well. then tried program mk20dn512vll through SWD port by cyclone universal.

    but it's failed to program show error 000007.
    hardware connection is SWD, SWCLK, GND connection between board and cyclone.
    i din't know why. do i have problen swd connection? or image making?

    please answer.



  • Greetings,

    You must have VDD connection as well. This should be the case for all other programming projects you have done in the past. The VDD is not just for providing power to target, but it is the reference voltage and the cyclone has no idea whether 3V is high or low or floating. Once you have VDD connection everything should work perfectly.
