Compability with 2.4 format.

[Krezalis]

Unsupported compressed VBF 2.4 version:
Data format identifier:
data_format_identifier =
0x00 = Uncompressed
0x10 = Compressed - used LZSS compression
0x01 = Encrypted ?

Yes, VBF since v2.4 don't supported. If anyone want's to help with it I would be appreciative 😃

So, if we have data_format_identifier = 0x10 its mean that binary image compressed with LZSS algorithm.
And CRC calculated of unpacked image.
I think SBL unpack image inside ECU. In example full flash contained 16M, compressed 3M. Its busted time to upload FW to ECU.

Thanks for clarify it for me. I'll try to add it soon.
Also could you send to me any vbf with compression? (of course if you have it :)
