The image is +# produced by constructing a special header which is +# then tacked onto the front of the supplied binary +# image. The resulting binary image is smaller than +# what would normally be encountered with traditional +# download formats (such as SREC or uuencoded; both +# ascii based). The special header at the front of the +# image is used to guide the target's rrload (a +# booloader developed by RidgeRun Inc). The header +# data contains a field representing the total byte +# count of the binary data following the header as +# well as a field that indicates the load address of +# run image. Additionally, a field exists in the +# header which indicates the image's entry point which +# could be called by the bootloader to invoked the +# just downloaded program. +# ----------- +# Scenario #2 +# ----------- +# If the supplied image is not a standard binary +# executagle image then that is ok too, a header is +# constructed and tacked onto the front of the supplied +# binary data forming the new binary image (in rr format). +# In this case the EntryAddr is set to 0xFFFFFFFF by +# default and the LoadAddr is set to 0x00000000 by +# default unless otherwise indicated by command line +# arguments -LEntry and -LAddr which if used are assumed +# to be in hexidecimal units. +# +# ----------- +# Scenario #3 +# ----------- +# +# Read/Write file system (like JFFS) that will not +# work if rrload stores a 20 byte header at the beginning +# of the flashed component image +# +# mkimage [--NoHeader ] <input-bin> <out-RR> +# +# Usage: +# mkimage [--LAddr h] [--EAddr h] [--NoHeader] <input-bin> <out-RR> +# +# Examples: +# $ mkimage linux linux.rr +# ..or.. +# $ mkimage -LAddr 10008000 -EAddr 10008000 vmlinux vmlinux.rr +# ..or.. +# $ mkimage --NoHeader fileSys.gz fileSys.gz.rr +# ..or.. +# $ mkimage --LAddr A00 fileSys.gz fileSys.gz.rr +# ..or.. +# $ mkimage --LAddr A00 fileSys.gz fileSys.gz.rr +# ^ +# | +# Assumed hex units. +# Please omit the +# leading "0x". +######################################################## + +if [ $# -lt 2 ] ; then + echo "Error: missing argument" + echo "Usage: mkimage [--Prefix prefix] [--LAddr n] [--EAddr n] [--NoHeader] <input-Bin> <out-RR>" + exit 1 +fi + +# Pleae Note the following formatting inconsistency. +# (Sorry, for now this is necessary) +LoadAddr="00000000" # Note: hex val *without* proceeding "0x" +EntryAddr="0xFFFFFFFF" # Note: hex val *with* procedding "0x" + +unset prefix +Header="y" +LAddrSupplied="n" +EAddrSupplied="n" +compress="n" + +while [ $# -gt 0 ] ; do + case "$1" in + --Prefix) + shift; + prefix="$1" + shift + ;; + --LAddr ) + shift + LoadAddr="$1" + # Next, make the supplied LAddr exactly 8 hex chars long. + LoadAddr="0000000${LoadAddr}" + LoadAddr=$(echo $LoadAddr | sed -e "s/^.*\(........\)$/\1/g") + LAddrSupplied="y" + shift + ;; + --EAddr ) + shift + EntryAddr="$1" + # Next, make the supplied LEntry exactly 8 hex chars long. + EntryAddr="0000000${EntryAddr}" + EntryAddr=$(echo $EntryAddr | sed -e "s/^.*\(........\)$/\1/g") + EntryAddr=0x$EntryAddr + EAddrSupplied="y" + shift + ;; + --NoHeader ) + Header="n" + shift + ;; + --compress ) + compress="y" + shift + ;; + *) + break + ;; + esac +done + +if [ ! $# -eq 2 ] ; then + echo "Error: invalid argument set." + echo "Usage: mkimage [--LAddr h] <input-Bin> <out-RR>" + exit 1 +fi + +binary=$1.stripped +outbin=$2 + +cp $1 $binary +FileTypeExec=$(${prefix}objdump -f $binary 2>/dev/null | egrep "EXEC_P") + +if [ ! -z "$FileTypeExec" ] ; then + + # ----------- + # Scenario #1 + # ----------- + # We have an executable style binary (like ELF, etc). + # So... + # --------------------------------- + # Next | Create the binary image data. + # --------------------------------- + ${prefix}strip ${binary} + ${prefix}objcopy -S -O binary $binary ${binary}.binary + # --------------------------------- + # Next | Create compress image if requested + # --------------------------------- + image_file=${binary}.binary + if [ "$compress" = "y" ] ; then + gzip -f -9 -c ${binary}.binary > ${binary}.binary.gz + image_file=${binary}.binary.gz + fi + # --------------------------------- + # Next | Create the header information (ascii) needed + # | by the TI925 bootloader.
