BOLD = SIZE of FIt-Image

Process of generation of Image-signed.bin
SIZE of FIT-Image =0x0245bbb4
 
Extracting size from Image header...
SIZE= "0x`od -t x4 -j 0x4 -N 0x4 --endian=big fitImage-image | head -n1 | awk '{print $2}'`"
IVTOFFSET=SIZE
IVTSIZE="0x20"
CSFOFFSET  = ((IVTOFFSET + IVTSIZE))
 
Padding Image file...
objcopy -I binary -O binary --pad-to=$SIZE --gap-fill=0x00 fitImage-image Image-pad.bin
 
genIVT.pl is copied bellow 
chmod +x genIVT.pl
./genIVT.pl
cat Image-pad.bin ivt.bin > Image-pad-ivt.bin
 
Generating CSF binary...
csf_image.txt is copied bellow
 
./cst -i csf_image.txt -o csf_image.bin
 
# copy signatures into binary
cat Image-pad-ivt.bin csf_image.bin > Image-signed.bin
rm Image-pad*
 
"Image-signed.bin is ready!"
 
 
 
cat csf_image.txt

Like this way I generated Image-signed.bin from FIT-IMAGE
