The good news is that I have a prototype driver for the cx2388x... So far it can talk w/ the devices on the I2C bus (which is the easy part): -bash-2.05b$ ./iic -f /dev/iic0 START 0xa0 WRITE 1 0 STOP START 0xa1 READ 5 06 ff ff ff 02 Though the bad news is that Linux (2.6.20.7) doesn't support my version of the NXT.. Linux only supports the TUV1236D when 04 or 05 in the first byte above, so I'm not sure what type of device I have.. I've sent a request to NXP for informating on the tuner, I'll see how they respond... Though if you have a card w/ an LG H062F, like the DViCO FusionHDTV5 Gold or the PCHDTV HD5500 , a bit of mash up between my bktraucap program and the cxd driver, and you'll be able to tell me how your computer crashes! :) (Though I'll need to add ioctl's to flip GPIO lines for you.) The source for the driver is in perforce at: http://p4web.freebsd.org/@md=d&cd=//&c=Pbj@//depot/user/jmg/cxd/?ac=83 Let me know if you're interested in working on it. cxd0: <Conexant CX23880 MPEG> mem 0xe5000000-0xe5ffffff irq 17 at device 7.2 on pci1 iicbb0: <I2C bit-banging driver> on cxd0 iicbus0: <Philips I2C bus> on iicbb0 master-only iicbus0: <unknown card> at addr 0 iic0: <I2C generic I/O> on iicbus0 cxd0: [ITHREAD] -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
