使用mkimage生成boot.scr

1、mkimage工具 

直接运行mkimage得到一下信息: 

mkimage [-x] -A arch -O os -T type -C comp -a addr -e ep -n name -d data_file[:data_file...] image

          -A ==> set architecture to 'arch'
          -O ==> set operating system to 'os'
          -T ==> set image type to 'type'
          -C ==> set compression type 'comp'
          -a ==> set load address to 'addr' (hex)
          -e ==> set entry point to 'ep' (hex)
          -n ==> set image name to 'name'
          -d ==> use image data from 'datafile'
          -x ==> set XIP (execute in place)

2、编写boot.script文件

if fatload mmc 0 80200000 uImage
then
 echo ***** Kernel: /dev/mmcblk0p1/uImage *****
fi
echo ***** RootFS: /dev/mmcblk0p2 *****
setenv bootargs 'console=ttyS2,115200n8 androidboot.console=ttyS2 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off mpurate=1000 omap_vout.vid1_static_vrfb_alloc=y'

bootm 0x80200000 

3、使用mkimage生成boot.scr

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute uImage.bin' -d boot.script boot.scr
