Dumping The XIP Partition

[mousey_]

How Do I Dump The XIP Partition Of A Hermes ROM? I Read The How to Dump A Hermes ROM And It Labels Two Different Sections As Containg The XIP. So How Do I Get The Right One, I'd Like To Get XIP.bin Like The Huy Who Posted The XIP.bin For WM6 Trinity.

First you have to remove 8 bytes every 0x200 bytes from OS.nb, as shown in the attached picture (you can do this with a script using 'dd').

After that, you can use dumprom as usual to extract the XIP section:

mkdir XIP
dumprom.exe -5 modified_os.nb -d XIP

What Script Would I Need For The 'dd' Command?

What Script Would I Need For The 'dd' Command? The shell or perl script you'll write for yourself, so you won't have to repeat the same task more than once ... and Will Parse Your Posting To Convert Every Capital Letter To Lower Case :D

Something similar to this:


#!/bin/sh
FILE="$1"
if [ ! -e $FILE ] || [ -z $FILE ]; then echo "missing input file (OS.nb)" ; exit 1 ; fi

len=`/bin/ls -l $FILE |awk '{print $5}'`
pass=$(( $len / 512 ))
skip=512
i=0

touch $FILE.out

while [ $i -le $pass ]; do

if [ $i == 0 ]; then
skip=0
else
tmp1=$(( 512 * $i ))
tmp2=$(( 8 * $i ))
skip=$(( $tmp1 + $tmp2 ))
fi

dd if=$FILE of=$FILE.tmp.$i bs=1 skip=$skip count=512
cat $FILE.out $FILE.tmp.$i > $FILE.tmp
mv $FILE.tmp $FILE.out
rm $FILE.tmp.$i

i=$(( $i + 1 ))

done
