i can give you these files
but what do you want to do I still do not understand

very interesting
do you know this algorithm GM
seed/key
FA5D/75BF
21CC/8384
6651/6C2D
56AB/CD6A
EA25/D4BD
3986/12C7
2E04/1C84
C396/E6D8
3314/E687
77BC/AF8E

absolutely known
what is this 19 algorithm
3 level

who knows the calculation formula

if you like arduino
look this

Thanks for the quick response
I practically do not work with calibrations
north american cars
my specialty is opel

maybe so ? universal XML for files of different lengths but with the same header. I often have to work with segments it would also be very convenient to extract segments to a folder called as OS and then just segments here with such a template 12598219.00 12598439.02 --------------------- 12610597.0...

Good afternoon !
I want to check the checksums
file which consists of one segment
file = segment
for example this
I already broke my head
trying to write xml
there is no way to indicate
that segment address is the beginning - the end of the file

yes you're right any standard programming consists of two parts this is programming the main software if it has changed and calibration programming but this is only the first part further win programming takes place programming date programmer number some operations on binding a block to a car, etc....

Yeah I understand. Im more focusing on making my own custom kernel so I can read/write to absolutely any address including the parameter block which has VIN/Seed/Key ect. if you are talking about a memory area from 0xc000 to 0x10000 then this is emulation of non-volatile memory in flash there are s...

if you want to program the whole block
in one piece
but modified files
there’s still a lot to fix
much easier to use the standard procedure
breaking a common piece into pieces like GM does

if you want to do programming just like sps does then in addition to software and calibrations, nothing more needs to be programmed if checksums are already calculated in the file if the checksums are not yet corrected this can be done on the fly before programming memory area where you still found ...
