UHD - USRP2 App Notes
========================================================================
.. contents:: Table of Contents
------------------------------------------------------------------------
Building firmware and FPGA images
------------------------------------------------------------------------
^^^^^^^^^^^^^^^^^^
FPGA Image
^^^^^^^^^^^^^^^^^^
Xilinx ISE 10.1 is required to build the FPGA image for the USRP2
(newer version of ISE are known to build buggy 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.
Run the following commands:
::
cd <uhd-repo-path>/fpga/usrp2/top/u2_rev3
make bin
*The image file will be ./build/u2_rev3.bin*
^^^^^^^^^^^^^^^^^^
Firmware Image
^^^^^^^^^^^^^^^^^^
The Microblaze GCC compiler from the Xilinx EDK is required to build the firmware.
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.
Run the following commands:
::
cd <uhd-repo-path>/firmware/microblaze
./boostrap
./configure host=mb
make
*The image file will be ./apps/txrx.bin*
------------------------------------------------------------------------
Load the images onto the SD card
------------------------------------------------------------------------
**Warning!**
Use the u2_flash_tool with caution. If you specify the wrong device node,
you could overwrite your hard drive. Make sure that --dev= specifies the SD card.
Load the FPGA image:
::
cd <uhd-repo-path>/firmware/microblaze
sudo ./u2_flash_tool --dev=/dev/sd<XXX> -t fpga -w <path_to_fpga_image>
Load the firmware image:
::
cd <uhd-repo-path>/firmware/microblaze directory
sudo ./u2_flash_tool --dev=/dev/sd<XXX> -t s/w -w <path_to_firmware_image>
