Rom Tools/splitrom.pl

source can be found here

perl script to manipulate rom images.

• you can extract the various parts of a rom ( xipchain, osrom, bootloader, bootsplash, xipregion )
• you can insert parts into an existing base rom image.
• you can apply small ( several bytes ) patches to a rom.

splitrom understands all known WallabyFileFormats and HimalayaFileFormats.

Usage: splitrom <romimage(s)> [options]
   -wx xipchain                where to write xipchain
   -wo osrom                   where to write output image
   -wb bitmap                  where to write bitmap
   -wl bootloader              where to write bootloader
   -wm romsection:offset:length save romsection to file
   -wp xipsection:filename     save xipsection to .bin file
   -wi infoname                save NBF info to file

   -rl bootloader              which bootloader to use for NBF
   -n nbfinfotext              what NBF header to use [ex: PW10A1-ENG-3.16-007]
   -ri nbfinfofile             or where to read NBF header info from
   -wi nbfinfofile             where to save NBF header info
   -rx xipchain                where to get xipchain from
   -rb bitmap                  where to get bitmap from
   -rm romsection:offset       insert new romsection.

   -nl length                  size of the NBF header

   -ob offset                  where to find the bootup image
   -oe offset                  the end of the os image ( dfl: 0x81f00000 )
   -ol offset                  where to find the bootloader ( dfl: 0x80000000 )
   -oo offset                  the start of the os image ( dfl: 0x80040000 )
   -t NBF | NBA | B000FF | NB? | IMG type of result image (default is NB1)

   -db offset:data,data,...    write byte data to offset
   -dw offset:data,data,...    write word data to offset
   -dd offset:data,data,...    write dword data to offset
   -ds offset:string           write string data to offset ( with \ chars )
   -dl offset:file:offset:length  insert data from file at offset
