编译uboot时出现dtc: invalid option -- 'i'问题的解决

1：首先，出现这个问题是你的dtc问题，和uboot没有关系，不信你可以编译其他的版本试试
2：解决方案是：运行一下命令得到一个dtc.sh的脚本
    sudo  wget -c
如果出错了，则说明这个地址不能用了，你需要新建一个dtc.sh的文件，同时将下列文字复制到文件中

#!/bin/sh -e

check_dpkg () {
    LC_ALL=C dpkg --list | awk '{print $2}' | grep "^${pkg}" >/dev/null || deb_pkgs="${deb_pkgs}${pkg} "
}

unset deb_pkgs
pkg="bison"
check_dpkg
pkg="build-essential"
check_dpkg
pkg="flex"
check_dpkg
pkg="git-core"
check_dpkg

if [ "${deb_pkgs}" ] ; then
    echo "Installing: ${deb_pkgs}"
    sudo apt-get update
    sudo apt-get -y install ${deb_pkgs}
    sudo apt-get clean
fi

if [ ! -f ${HOME}/git/${project}/.git/config ] ; then
    git clone ${server}/${project}.git ${HOME}/git/${project}/
fi

if [ ! -f ${HOME}/git/${project}/.git/config ] ; then
    rm -rf ${HOME}/git/${project}/ || true
    echo "error: git failure, try re-runing"
    exit
fi

unset old_address
old_address=$(cat ${HOME}/git/${project}/.git/config | grep "jdl.com" || true)
if [ ! "x${old_address}" = "x" ] ; then
    sed -i -e 's:git.jdl.com/software:git.kernel.org/pub/scm/linux/kernel/git/jdl:g' ${HOME}/git/${project}/.git/config
fi

cd ${HOME}/git/${project}/
make clean
git checkout master -f
git pull || true

test_for_branch=$(git branch --list ${git_sha}-build)
if [ "x${test_for_branch}" != "x" ] ; then
    git branch ${git_sha}-build -D
fi

git checkout ${git_sha} -b ${git_sha}-build
git pull git://github.com/RobertCNelson/dtc.git dtc-fixup-65cc4d2

make clean
make PREFIX=/usr/local/ CC=gcc CROSS_COMPILE= all
echo "Installing into: /usr/local/bin/"
sudo make PREFIX=/usr/local/ install

3：输入命令chmod 777 dtc.sh
4:./dtc.sh
5:现在make一下你的uboot，应该是可以了，如果还不行就先make distclean 在make
6：还不行，那就联系我吧，[e-mail]，邮件不一定有时间回，可以直接加qq
