+UHD - Firmware and FPGA Image Application Notes
+========================================================================
+
+.. contents:: Table of Contents
+
+------------------------------------------------------------------------
+Images Overview
+------------------------------------------------------------------------
+Every USRP device must be loaded with special firmware and FPGA images.
+The methods of loading images into the device varies among devices:
+
+* **USRP1:** The host code will automatically load the firmware and FPGA at runtime.
+* **USRP2:** The user must manually write the images onto the USRP2 SD card.
+
+------------------------------------------------------------------------
+Pre-built images
+------------------------------------------------------------------------
+
+Pre-built images are available for download.
+See the UHD wiki for the download link.
+
+The pre-built images come in platform-specific installer packages
+and platform-independent archive files:
+
+* **Linux:** DEB or RPM installer
+* **Windows:** not available yet...
+* **Macintosh:** not available yet...
+* **Platform-independent:** ZIP or TAR.GZ archive
+
+^^^^^^^^^^^^^^^^^^
+Linux installers
+^^^^^^^^^^^^^^^^^^
+The Linux-based installers will install the images into /usr/share/uhd/images.
+On a Linux system, the UHD will always search this path for image files.
+
+Commands to install a linux rpm or deb package:
+
+::
+
+ sudo rpm -i <linux-images-installer>.rpm
+
+ -- OR --
+
+ sudo dpkg -i <linux-images-installer>.deb
+
+^^^^^^^^^^^^^^^^^^^^^^
+Archive install
+^^^^^^^^^^^^^^^^^^^^^^
+When installing images from an archive, there are two options:
+
+**Option 1:**
+
+Unpack the archive into the UHD installation prefix.
+The UHD will always search <prefix>/share/uhd/images for image files.
+Where <prefix> was set by the CMAKE_INSTALL_PREFIX at configure-time.
+
+**Option 2:**
+
+Unpack the archive anywhere and set the UHD_IMAGE_PATH environment variable.
+The UHD_IMAGE_PATH may contain a list of directories to search for image files.
+
+------------------------------------------------------------------------
+Building images
+------------------------------------------------------------------------
+
+The UHD source repository comes with the source code necessary to build
+both firmware and FPGA images for all supported devices.
+The build commands for a particular image can be found in <uhd-repo-path>/images/Makefile.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Xilinx FPGA builds
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Xilinx ISE 12.x and up is required to build the Xilinx FPGA images.
+The build requires that you have a unix-like environment with make.
+Make sure that xtclsh from the Xilinx ISE bin directory is in your $PATH.
+
+See <uhd-repo-path>/fpga/usrp2/top/*
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Microblaze firmware builds
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The Microblaze GCC compiler from the Xilinx EDK is required to build the Microblaze firmware images.
+The build requires that you have a unix-like environment with autotools and make.
+Make sure that mb-gcc from the Xilinx EDK/microblaze directory is in your $PATH.
+
+See <uhd-repo-path>/firmware/microblaze
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Altera FPGA builds
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Quartus is required to build the Altera FPGA images.
+Pre-built images can also be found in <uhd-repo-path>/fpga/usrp1/rbf
+
+See <uhd-repo-path>/fpga/usrp1/toplevel/*
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+FX2 firmware builds
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The sdcc compiler is required to build the FX2 firmware images.
+The build requires that you have a unix-like environment with autotools and make.
+
+See <uhd-repo-path>/firmware/fx2
