Details
split_firmware is a statically linked tool to split a firmware image into fixed size parts.
fbf 1.135 help:
split_firmware: -i <input-file> -1 <output-1-file> [-s buffersize-1] [-S buffersize-2]
This help lacks the -2 <output-2-file> part. The buffersizes must be hexadecimal.
The output images are fixed size, regardless of the input. If the input is bigger than the
first buffer it will overlap into the second buffer, otherwise the second buffer is untouched.
Examples
From fbf 1.135 post_install created by install: - the input file is 2.3 MB.
split_firmware -i filesystem.image -s 0x2B0000 -S 0x50000 -1 /var/tmp/filesystem.1.image -2 /var/tmp/filesystem.2.image
filesystem.1.image is is the 2.7 MB filesystem which goes to mtd0 (linux):
copy_firmware -u -i /var/tmp/filesystem.1.image -o /dev/mtdblock/0
filesystem.2.image is 320 KB untouched, 2x 128 KB TFFS + 64KB for the old_config - the combo goes to mtd3 (linux):
flash_tffs -H /var/tmp/filesystem.2.image -s 0x10000 -c /var/old_config -t 0x20000 -o /var/tmp/mtd3.image copy_firmware -u -i /var/tmp/mtd3.image -o /dev/mtdblock/3
old_config is the old envorinment preserved by install_env:
cat /proc/sys/dev/adam2/environment >/var/old_config
