hi again! @bigdogguru, thank you for support, i realy have no alternatives to test this example on Xilinx board. The kit is this - Digilent Spartan-3E Starter Kit (500K), rev D, and u are right - in EDK i can select Xilinx as manifacurer, but i have no option for Digilent version. Realy i was surpised to understand there are two versions (Dig. and Xil.) of this board with a bit but important differences. this is my example created by SDK (noted with this suffix), and EDK project. I remove documents to get low size of file and i place them in separate rar if u need to see versions of modules.
