hi everyone,
i'm trying out kbtv on my shiny new 6.2-release of last week, but i can't get it to get any display.
to my pleasant surprise the maintainer of kbtv has resumed development a few days ago and released a new version 1.2 of kbtv. also with that one, i can't get any channel (previously i tried with vs 1.1.3). so i was wondering where things go wrong: either the tuner or the chip to receive images.
concerning the tuner, i built the tools under kbtvs support directory and the tune_channels seem to work correctly: the ioctls performing I2CSTART, I2CSTOP, I2CREAD and I2CWRITE exit all with 0, so i assume this is working like it should:
ioctl(3,I2CSTOP,0xbfbfeb70) = 0 (0x0)
ioctl(3,I2CSTART,0xbfbfeb70) = 0 (0x0)
ioctl(3,I2CREAD,0xbfbfeb70) = 0 (0x0)
ioctl(3,I2CSTOP,0xbfbfeb70) = 0 (0x0)
this may leads me to the saa driver (included in the kbtv, and not the freebsd base system, anyone knows why?):
i tried building it with the different makeflags, as described in the Makevars, but always with the same result: no image
my hardware, from pciconf -lv:
saa0@pci3:1:0: class=0x048000 card=0x00497416 chip=0x71341131 rev=0x01 hdr=0x00
vendor = 'Philips Semiconductors'
device = 'SAA7134HL Multi Media Capture Device'
class = multimedia
the readme says it support SAA7134x, but i'm starting to wonder whether my saa7134HL resorts to that? does anyone know?
dmesg gives me:
saa0: <Phillips SAA7134 AV broadcast decoder> mem 0xd8000000-0xd80003ff irq 17 at device 1.0 on pci3
i also am not sure about the tuner type. i know it's a philips, but there is also a philipsMK2 and MK3 models. does anyone know how to get this information?
i'm now looking into the source code of the saa and kbtv for adding debug statements, and also reading up about i2c and such, but i'm far from an expert. so if anyone has any experience with this card or with kbtv, let me know. i'd love to get this card working under freebsd
tnx in advance,
filip
