Subject: cx23888 board setup
Date: Tue, 19 Oct 2010 17:54:36 -0400 [thread overview]
Message-ID: <4CBE139C.8000508@adiengineering.com> (raw)
We have a custom x86 board with:
- A soldered down cx23888
- Four composite inputs feeding the cx23888. No tuner.
We're only looking at the four composite inputs.
- FC13 with a 2.6.33.4 kernel.
The cx23885 driver loads and I get /dev/video0 but when I try to
cat /dev/video0 I get data but it's not an mpeg file.
Can anyone point me to some documentation which tells how to set
up the cx23885_board board structure and what other
initialization might need to be done?
In the cx23885 driver I modified cx23885-cards.c to add an
entry for our hardware.
struct cx23885_board cx23885_boards[] = {
[CX23885_BOARD_ECU] = {
.name = "custom board",
.porta = CX23885_ANALOG_VIDEO,
.portb = CX23885_MPEG_ENCODER,
.clk_freq = 50000000,
.input = {{
.type = CX23885_VMUX_COMPOSITE1,
.vmux = 0,
}, {
.type = CX23885_VMUX_COMPOSITE2,
.vmux = 1,
}, {
.type = CX23885_VMUX_COMPOSITE3,
.vmux = 2,
}, {
.type = CX23885_VMUX_COMPOSITE4,
.vmux = 3,
} },
},
cx23885_subids
}, {
.subvendor = 0x0000,
.subdevice = 0x0000,
.card = CX23885_BOARD_ECU,
}, {
