Clean ran for a project will clean only the project files.
Clean-all ran for a project will clean also the library files on which the project depends.
The clean commands will only remove specific files and directories.
The top Makefile allows several options(per suggestion from jameyhicks):
make fmcomms1.zed will run "make all" in projects/fmcomms1/zed/
make clean will run "make clean" for all the projects
make clean-all will run "make clean" for all the projects and libraries
make lib will run "make all" for the library files
ZC706 runs rx_clk at 250 MHz.
ZC702 and ZED run rx_clk at 200 MHz due to slower fabric.
The ZC702 and ZED projects need init_user in the boot procedure in order for the HP Ports to work correctly.
Both DDS and DMA mode work.
