ISPEditor

ISPBOOOT.BIN file editor good for scripting and automation.

Usage: ./ispe <img> [-v] <cmd> [cmdparams]
        [-v] verbose mode (-vvv.. increase verbosity)
        <cmd> [params] one of the following:
        list - list partitions in the image
        crea - create an empty image
        extb <0xXX> <dlen> - extract <dlen> (dec) bytes at XX offset
        setb <0xXX> <name> - save raw binary file <name> at <0xXX> offset
        head exts - extract header script
        head flag <0xXX> - set image header flag
        head sets <file> - update header script from script image file
        part <name> dele - delete the partition from the image
        part <name> addp - create new partition
        part <name> extp - extract partition to ...
        part <name> file <file> - load data for the partition from the raw file
        part <name> flag <0xXX> - set flag = 0xXX to partition <name>
        part <name> size <0xXX> - set size = 0xXX to partition <name>
        part <name> nand <0xXX> - set NAND offset = 0xXX to partition <name>
        part <name> emmc <0xXX> - set EMMC start block off = 0xXX

EXIT_CODE == 0 on success:

./ispe ./myimage ...
if [ $? -ne 0 ]; then  echo "Failed";
else  echo "OP is done";  fi;

Please, see test0.sh for more examples.

Building

make

for Plus1 (sp70*) SoCs or

make CFLAGS+="-DSOC_SPHE"

Build Requirements:

• openssl-dev package (libssl, libcrypto + headers)

Runtime Requirements:

• bash >= 3.0
• mkimage (u-boot-tools package)

Examples

Generate EMMC ISP script for the existing image

ISPEDIR=. ispe-helpers/genisp.emmc.sh ./ISPBOOOT.BIN ./emmc.txt

Generate NAND ISP script for the existing image

ISPEDIR=. ispe-helpers/genisp.nand.sh ./ISPBOOOT.BIN ./nand.txt

Show ISPBOOOT.BIN data

./ispe ./ISPBOOOT.BIN list

Create new empty image

./ispe ./ISPBOOOT.BIN -vvv crea

Set image header flag

./ispe ./ISPBOOOT.BIN head flag 0x01

0x01 means MTD_ONLY

Add new empty partition

./ispe ./ISPBOOOT.BIN part "part0" addp

Load data to the partition

./ispe ./ISPBOOOT.BIN part "dtb" file ./isp.p.dtb

Extract script

./ispe ./ISPBOOOT.BIN head exts

sript will be dumped into isp.h.script.raw - raw script buffer dump (need to cut last \0 to operate) isp.h.script.txt - attempt to extract clear text

Encode plain text in 'isp.h.script.txt' file to image script

./script_enc.sh ./isp.h.script.txt ./isp.h.script.raw

Attempt to get script RAW image information from 'isp.h.script.raw':

sed 's/\x00*$//' ./isp.h.script.raw > ./isp.h.script.raw.tmp
mkimage -l ./isp.h.script.raw.tmp

Update the header script from script text file:

./ispe-helpers/script_enc.sh "Init ISP Script" ./myscript.txt ./myscript.raw
./ispe ./ISPBOOOT.BIN head sets ./mysript.raw

Extract binary raw data

./ispe ./ISPBOOOT.bin extb 0x100 16

Extracts 16 bytes starting at 0x100 offset into 'isp.b.100.16' file

Set binary raw data

./ispe ./ISPBOOOT.bin setb 0x100 ./isp.b.100.16

Saves the raw file contents from the file 'isp.b.100.16' to the image starting at 0x100 offset. IMG Header is protected.

Hope it helps
