Booting from EPC4

I had the same problem with the quartus i belive what you have done is to delete the deley_rest_block

if so that is a mistake.

try to add it back , if you need the vhdl file that define this block look for them in the example file of the standart project ,

you will need to add a PLL and to tie all the input and output of the the system to the right pins of the cheep , look at the standart project for example
