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>
