lUnpack

Once you've download the source code for the , you can unpack the source archive by doing (replace u-boot-2013.07-2013R1.tar.bz2 with whatever filename you downloaded if it is not the same):

$ tar jxf u-boot-2013.07-2013R1.tar.bz2 

Now simply change directory to the U-Boot directory that was just created (replace u-boot-2013.07-2013R1 as applicable):

$ cd u-boot-2013.07-2013R1

Configure/Build

Then run the following commands:

 

The Blackfin toolchain must be installed before U-Boot can be compiled. For more information, see .

 

 交叉工具下载：

 

$ tar jxf blackfin-toolchain-2013R1-RC1.i386.tar.bz2

$ tar jxf blackfin-toolchain-2013R1-RC1.src.tar.bz2

$ tar jxf blackfin-toolchain-elf-gcc-4.3-2013R1-RC1.i386.tar.bz2 

$ tar jxf blackfin-toolchain-uclibc-full-2013R1-RC1.i386.tar.bz2

$ tar jxf blackfin-toolchain-uclibc-full-2013R1-RC1.src.tar.bz2

添加到环境变量

$ export PATH=$PATH:/home/ubuntu/Evan/003.ADSP/U-boot/adi-u-boot/toolchain/opt/uClinux/bfin-uclinux/bin:/home/ubuntu/Evan/003.ADSP/U-boot/adi-u-boot/toolchain/opt/uClinux/bfin-linux-uclibc/bin

Alternately, to have PATH set automatically edit the file ~/.bashrc to include the following lines:

export PATH=$PATH:/home/ubuntu/Evan/003.ADSP/U-boot/adi-u-boot/toolchain/opt/uClinux/bfin-uclinux/bin:/home/ubuntu/Evan/003.ADSP/U-boot/adi-u-boot/toolchain/opt/uClinux/bfin-linux-uclibc/bin When your system is localized, you may or may not prefer to have all build output in native english or your localized language, where english supports forum information exchange. Setting english (whether in all shells or a single one, see above):

 

$ export LANG=C

$ make 

 Replace  with the specific board you are using. See the  list for board configs that may be available depending on the release.

 $ make bf518f-ezbrd_config

The BFIN_BOOT_MODE define in the board configuration file controls the board boot mode (parallel flash / serial flash / uart / etc…). See the customizing document for more information.

Every board port has its own board config file, and largely all customizable settings live there. You can usually find it at include/configs/.h.

Compiler related settings are placed in the board-specific config.mk which can usually be found at board//config.mk.

If you make changes to these files, you should probably run make clean to make sure all changes take effect.
