    Do you have an SD card installed? If so, the HPS is probably booting and then reconfiguring the FPGA back to its default design.

    (I didn't intend to click the accept button! My problem isn't solved.)

    Yes I already have inserted the SD card in my board. ;(

    Sometimes the loaded data is gone and sometimes it remains.

    What is the problem.. ~~
