incbuild

motorola自己开发的针对coldfire 5272的Dbug bootloader程序

#
# File:		incbuild file
# Purpose:	Script to increment BRD_BUILD variable
#
# Notes:	This script works only with a file that contains the
#			following lines in this exact order:
#
#				const int  BRD_BUILD = X ;
#				const char BRD_TIME = __TIME__ ;
#				const int  BRD_DATE = __DATE__ ;
#
#			This script knows exactly which piece is the variable
#			to increment.  Do not attempt to use with any other
#			type of file.  It will not work!
#
#			It is ideal to write a more robut script that is able
#			to find BRD_BUILD and replace the value in the file
#			but this will do for now...

chmod o+w $1

#
# Step 1) Check for valid filename/argument
#
if [ $# = 0 ]
then
	echo usage: $0 filename
	exit
fi

if [ ! -r $1 ]
then
	echo error: $1 is not readable!
	exit
fi

if [ ! -w $1 ]
then
	echo error: $1 is not writable!
	exit
fi

#
# Step 2) Parse out current value
#
position=0
for piece in `cat $1`
do
	position=`expr ${position} + 1`
	if [ ${position} = 5 ]
	then
		build=`expr ${piece}`
		build=`expr ${build} + 1`
	fi
done

#
# Step 3) Now update file with new build number
#
echo const int BRD_BUILD = ${build} \;		>  $1
echo const char BRD_TIME[] = __TIME__ \;	>> $1
echo const char BRD_DATE[] = __DATE__ \;	>> $1

echo BRD_BUILD = ${build}
