[linux-dvb] Re: Full featured card summary

[Andrew de Quincey <adq_dvb@lidskialf.net>]

Incidentally, even though the firmwares used by 1.0.0 and 1.1.0 have the same 
version number, they are _not_ the same.

1.0.0 had two seperate files, Dpram and Root
1.1.0 has a combined file, dvb-ttpci-01.fw

However the file format of dvb-ttpci-01.fw is obvious: 
4 byte magic
4 byte number (probably a date)
4 byte length of Dpram
<Dpram data>
<Root data>

I extracted the Dpram and Root from dvb-ttpci-01.fw. 
Additionally, the two Roots are slightly different lengths, but the end of the 
file is full of padding. I chopped a bytes off the end of each so they were 
the same length (this is the "Root2" below). Results:

1.0.0:
[adq@monstrousfish av7110]$ md5sum Dpram
65edabe40061f0e5b0a5d2eb6cbf9132  Dpram
[adq@monstrousfish av7110]$ md5sum Root2
abfbffc0bef9fde14e5eb28ad6da66c0  Root2

1.1.0:
[adq@monstrousfish build-2.4]$ md5sum Dpram
24b2e6e396d18883074aa88879094999  Dpram
[adq@monstrousfish build-2.4]$ md5sum Root2
b8668b7f2a744a254d3e49409dcde813  Root2
