-All files located in ''​%%src/​%%''​ will be compiled against the application specified to generate the binary. ​Finally, ​a ''​%%BOOT.bin%%''​ file (binary image that is used for booting off the SD caredcan be created through the utilization of the ''​%%doit%%''​ script. ​+All files located in ''​%%src/​%%''​ will be compiled against the application specified to generate the binary.

 +==== Programming & Debugging ==== 
 +In order to generate ​boot-able ​''​%%BOOT.bin%%''​ file (binary image that is used for booting off the SD card), utilize ​the ''​%%doit%%''​ script ​in the ''​%%software/​%%''​ directory

- +In order to efficiently debug through GDB and program on the fly, the [[https://​store.digilentinc.com/​jtag-hs3-programming-cable/​|Digilent HS3]] can be used as a JTAG access point for GDB debug interfaces. To interact with the HydroZynq through JTAG, use the ''​%%xmd%%''​ command (provided by the Xilinx Vivado tool suite).
-==== Cross-Compile FFTW3 ==== +
-In order to perform frequency analysis, the HydroZynq utilizes the FFTW3 libraries. In order to generate the libfftw3.a library ​and the associated header filesit is necessary to compile FFTW from scratch. This can be completed by downloading ​the FFTW tarball from [[http://​www.fftw.org/​download.html|here]]. Next, untar the tarball, create an output directory for the library and headers, and configure FFTW before installation with the following options: +
-  mkdir build +
-  ./configure --host=arm-none-eabi "​CFLAGS=--specs=nosys.specs -mcpu=cortex-a9 -mfpu=vfpv3 -mfloat-abi=hard"​ --enable-armv7a-cntvct --prefix=`pwd`/​build +
-  make -j4 +
-  make install +
- +
-The library and appropriate headers will now be in the ''​%%build/​%%''​ directory. +
- +
-==== Programming & Debugging ==== +
-Programming and debugging can be completed through creation of a new ''​%%BOOT.bin%%''​ on the SD card, but this is often inefficient. The [[https://​store.digilentinc.com/​jtag-hs3-programming-cable/​|Digilent HS3]] can be used as a JTAG access point for GDB debug interfaces. To interact with the HydroZynq through JTAG, use the ''​%%xmd%%''​ command (provided by the Xilinx Vivado tool suite).+
