    MiniProg3 cant program from 5V

    external.solutions

      Hi all,

         

      I buying from Farnell a MiniProg3 REV B and i have a big problem of my programmer.

         

      I cant program my devices from 5V. I connect my oscilloscope to SDAT, SCLK and VTARG lines and changing power supply voltage 1.8V to 5V.

         

      Not working from externally power and internally both.

         

      1.8V to 3.3V its ok. The lines follow the voltage. But 5V only follow VTARG. SCLK and SDAT stay on 3.3V. Why?

         

       

         

      Sorry for my bad english.

         

       

         

      Best regards:
