Hi!! I'm trying to use SKY7104 CCTV (4 channel video capture card). Kernel autoload module saa7134 but flag it as unknown,register two video devices but it seems not work. Someone could help me to patch saa7134 driver?
windows drivere are availabe here: http://www.cn-dvr.com/products/enproducts78.html#1 Card has 4 bnc video inputs, 1 rca video output, 10 GPIO. All signatures on chips was removed.... One chip is near vido output and I think it is video buffer. Another chip is near saa7134 and I think it an i2c eeprom. A quartz of 24.576Mhz is connected to saa7134. There are a DIP chip (It could be a microchip pic) with a 11.0592 quartz connected to saa7134 and to a relais with two outputs marked as "RESET". It could be something like a wachdog to connect to motherboard reset switch. I can check exactly where is connected each saa7134 pin. lspci -v 00:01.0 Multimedia controller: Philips Semiconductors SAA7130 Video Broadcast Decoder (rev 01) Subsystem: Philips Semiconductors Device 0000 Flags: bus master, medium devsel, latency 64, IRQ 16 Memory at febffc00 (32-bit, non-prefetchable) [size=1K] Capabilities: [40] Power Management version 1 Kernel driver in use: saa7134 Kernel modules: saa7134 lspci -vn 00:01.0 0480: 1131:7130 (rev 01) Subsystem: 1131:0000 Flags: bus master, medium devsel, latency 64, IRQ 16 Memory at febffc00 (32-bit, non-prefetchable) [size=1K] Capabilities: [40] Power Management version 1 Kernel driver in use: saa7134 Kernel modules: saa7134 dmesg [75996.656618] saa7130/34: v4l2 driver version 0.2.15 loaded [75996.656840] saa7130[0]: found at 0000:00:01.0, rev: 1, irq: 16, latency: 64, mmio: 0xfebffc00 [75996.656857] saa7134: <rant> [75996.656860] saa7134: Congratulations!
