[linux-dvb] Re: Full featured card summary
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
