[linux-dvb] Problems with Nebula DigiTV.

[Clyde Stubbs <clyde@htsoft.com>]

Hi, I'm having trouble getting a Nebula DigitTV card to go -
have patched the kernel (2.4.22) for v4l2, got bttv, got
dvb CVS etc. All the modules load ok, but I get these
debug messages:

 Linux video capture interface: v1.00
 bttv: driver version 0.9.11 loaded
 bttv: using 8 buffers with 2080k (520 pages) each for capture
 bttv: Host bridge is PCI device 10de:01e0 (nVidia Corporation)
 bttv: Bt8xx card found (0).
 bttv0: Bt878 (rev 17) at 01:06.0, irq: 11, latency: 32, mmio: 0xde000000
 bttv0: detected: Nebula Electronics DigiTV [card=104], PCI subsystem ID is 0071:0101
 bttv0: using: BT878(Nebula Electronics Digi) [card=104,autodetected]

 DVB: registering new adapter (Neb).
 nxt6000: attach
 nxt6000: nxt6000_read attempt (.addr = 0x14, reg: 0x73)  *** I added these printk's
 nxt6000: nxt6000_write attempt (.addr = 0x14, reg: 0x81, data: 0x01)
 nxt6000: nxt6000_write attempt (.addr = 0x14, reg: 0x81, data: 0x00)
 nxt6000: detected TI ALP510 tuner at 0xC0
 nxt6000: attached at 0:0
 dvb_register_frontend
 DVB: registering frontend 0:0 (NxtWave NXT6000)...
 
 ***** so far so good - but now I see this:
 
 nxt6000: nxt6000_read attempt (.addr = 0x18, reg: 0x73)
 nxt6000: nxt6000_read error (.addr = 0x18, reg: 0x73, ret: -121)
 nxt6000: nxt6000_read attempt (.addr = 0x24, reg: 0x73)
 nxt6000: nxt6000_read error (.addr = 0x24, reg: 0x73, ret: -121)
 nxt6000: nxt6000_read attempt (.addr = 0x28, reg: 0x73)
 nxt6000: nxt6000_read error (.addr = 0x28, reg: 0x73, ret: -121)
 bt878 debug: bt878_start (ctl=04004020)
 bt878: risc len lines 64, bytes per line 2048

any attempt to access the card (e.g. using tzap) just produces
more of the same, along with write errors, and failure.

It seems that after detecting the tuner, i2c reads and writes
always fail. But enough worked to detect the tuner
in the first place.

Anybody got any suggestions?

TIA, Clyde
