一、采用官方的制作U-boot（make CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm O=am335x am335x_evm）出现如下错误：
    . 问题：make: *** No rule to make target am335x_evm_config
        . cat Makefile:
            ......
            MKCONFIG        := $(srctree)/mkconfig
            export MKCONFIG
            ......
            %_config:: outputmakefile
                @$(MKCONFIG) -A $(@:_config=)
            ......

        . cat mkconfig
            if [ \( $# -eq  \) -a \( "$1" = "-A" \) ] ; then
                # Automatic mode
                line=`awk '($0 !~ /^#/ && $7 ~ /^'"$2"'$/) { print $1, $2, $3, $4, $5, $6, $7, $8 }' $srctree/boards.cfg`
                if [ -z "$line" ] ; then
                        echo "make: *** No rule to make target \`$2_config'.  Stop." >&
                        exit
                fi

                set ${line}
                # add default board name if needed
                [ $# =  ] && set ${line} ${}
            fi

    . 问题：生成u-boot.bin  error: bad value (armv5) for -march= switch
        http://arm9home.net/read.php?tid-82914.html
    . 解决方法：
        cat > remake.sh << EOF
        export CROSS_COMPILE=arm-linux-gnueabihf-
        export ARCH=arm
        make am335x_evm_config
        make
        EOF

二、文件系统跑起来之后无法得到Linux shell终端：
    #
    # The "id" field MUST be the same as the last
    # characters of the device (after "tty").
    #
    # Format:
    #  <id>:<runlevels>:<action>:<process>
    #
    #S::respawn:/sbin/getty  ttyO0
    ::respawn:/sbin/getty  ttyO0

三、重新生成.config文件：
    . 出错现象：
        Qt@aplex:~/kernel/linux-3.2.$ make uImage
        scripts/kconfig/conf --silentoldconfig Kconfig
        *
        * Restart config...
        *
        *
        * General setup
        *

          . XZ (KERNEL_XZ) (NEW)
          . LZO (KERNEL_LZO)
        choice[-?]:
    . 出现问题原因：
        cat ~/.bashrc
            ......
            CROSS_COMPILE=arm-linux-gnueabihf-
            ARCH=arm
            ......
    . 解决方法：
        cat ~/.bashrc
            ......
            export CROSS_COMPILE=arm-linux-gnueabihf-
            export ARCH=arm
            ......
四、tslib编译问题：
    . 出错现象：
         In function ‘open’,
             inlined from ‘main’ at ts_calibrate.c:::
         /usr/include/x86_64-linux-gnu/bits/fcntl2.h::: error: call to ‘__open_missing_mode’ declared with attribute error: open with O_CREAT in second argument needs  arguments
         In function ‘open’,
             inlined from ‘main’ at ts_calibrate.c:::

         make[]: *** [ts_calibrate.o] Error
