Hello nyusof,

thanks for your quick answer.

1) yes i have set the configuration scheme to Active serial

2)i did also disable the EPCS ID but it still not the same.

It is not a problem of silicon ID.The silicon ID has been recognized.

I have controlled my design again and check the signals with an oscilloscop.

+After programming the EPCS the nstatus line and the conf_done line still be low.

+After powerup the EPCS chip select NCS remain high and the clock SCL low.

thanks.
