Hi Anuradha C, May i know are you using the USB Blaster II to program the development kit? If it so, can you try to change the TCK frequency to 6MHz. You may refer to link below for the steps to change TCK frequency: https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd06242013_922.html Thank You.
