i am using altera cyclone 5 device, which is programmed through epcs16. initially for 2-3 days my card works well, but after that cyclone 5 is sending dclk signal again and again. i changed epcs16 and also resoldering cyclone 5, but the problem is not solved. i am facing this problem in 2-3 cards. kindly suggest me the appropriate solution for this.

Hi pmang2,

 

I suspect this issue due to problem with Serial Flash Loaderr (SFL) file in Quartus.

The workaround is to use user SFL with additional timing constraints.

 

Please refer to following KDB:

Thanks.😉
