Hello,
I bought a brandnew Hauppauge WinTV-NOVA HD-S2 which does not load the
firmware since the value of register 0x20 is allways 0x00. After changing the
cx24116 driver to not check register 0x20, the firmware is loaded and the
card works as expected (DVB-S, audio and remote control). Below are a few
details and the changes I made.
Any ideas why this is required for my card?
This is the card (lspci -vvv):

The following happens when I use the
command "scan /usr/share/dvb/dvb-s/Astra-19.2E". As you can see register 0x20
has the value 0x00. Regarding to the cx24116 source code I assume this should
be normally only the case when the firmware is already loaded. But there is
and was no firmware loaded into my card as the scan command is the very first
DVB command I execute.
Because register 0x20 has the value 0x00 it never loads the firmware and hence
I cannot use the card:

I have changed the following to get the firmware loaded:

}
This removes the check against register 0x20. Since the firmware is then
loaded on every command I have also removed the "state->skip_fw_load = 0".
This is a quick hack and has probably drawbacks, but it works for me. After
this changes the first DVB command loads the firmware and the card works as
expected:

The patch is for v4l-dvb-20100130, I use it together with Kernel 2.6.26 from
Debian Lenny. I have also tried Kernel 2.6.32 from backports.org but the
issue is exactly the same. Also the cx24116.c source of kernel 2.6.35-rc3 and
the latest version from the v4l-dvb HG repository contains the check for
register 0x20 so I assume it still can't work with my card.
I however do not fully understand the source that I have changed. I assume
that register 0x20 is normally unequal 0x00 when no firmware is loaded and
changes to 0x00 when a firmware is loaded. The question is then how do I
check this properly on my card where register 0x20 is allways 0x00
independently if a firmware is loaded or not?
Any idea why my card behave differently? Is it a new hardware revision or some
kind of a buggy card?
Thanks,
Andi
