Hi steven.
I used only files inside your exe file,so i didn't build anything different:
1) camera_demo\standard (project file);
2)SOPC --> Generate (that's ok);
3)Place new component on schematic standard file ready made;
4)Start compilation (ok);
5)programmin (ok);
6) Nios II,new,c\c++ project;
7)name(camera_demo),SOPC(sopc generated file),cpu(cpu),blank project;
8)camera_demo-->Import-->file system-->path\camera_demo-->(ok)
9)all files.h and files.c are been imported;
10) camera_demo-->Build project--> ERROR (those messages appear);
If i try to use your block (camera_dma,camera_if) i've address error.
What's wrong??
Bye
Paolo
