hello,
i've a difficulty in finding the end of gzipped image binary. it was a compressed linux kernel (i knew because it took random size, and unpack it though it showed an error). i knew that the crc and isize are supposed to placed in the end. but how do you know if it was it?
i was trying to read about how the crc calculated, i mean from where to where, but, i don't really get it after reading the gzip source code.
the image itself was placed in middle of another binary, which i'm not sure what it is yet. i tried with the longest size before another obvious border (another compressed image), but still can't get a good result.
regards
