Kirk-
Attached is your original patch that makes the flexcop driver use
nxt200x instead of nxt2002.
I've recently acquired this Air2PC card, and I've tested both nxt2002
and nxt200x with it. nxt200x works, but nxt200x doesn't. When using
nxt200x, the tuner cannot find a signal. (and it oops'd during a
frequency scan)
For the record, the nxt200x driver works *very* well, when used with the
nxt2004 chip, in the AVerTV HD a180... and Im sure it works well in the
ATi HDTV Wonder, since that is what Kirk used to write the driver.
Here is dmesg, first using nxt2002, then using nxt200x ... Azap'd to a
local ATSC tv station in 8VSB... after that, I scanned for channels
using nxt200x, and the oops output is below:
first with nxt2002:
mk@aftermath:~$ ./azap WPIX_Digital -r
