When I read this dump correct and it is my second linux dump I ever
seen, then in the function stb6100_set_frequency occures a divide by
zero exception.
There are only 2 lines in the function stb6100_set_frequency where a
division was made. In both lines the a divison by state->reference was made.
So I think that state->reference is zero, but normaly it was initialized
before in stb6100_init.
3 ideas:
1) a printk in stb6100_init to see, if the function was called (and
leave) before stb6100_set_frequency (or exception happens).
stb6100_init never gets called.
2) there is the possibility to give state->reference via stb6100_attach
via the config-parameter refclock in budget-ci.c:
struct stb6100_config tt3200_stb6100_config = {
.tuner_address = 0x60,
.refclock = 27000000,
};
That does the trick. Thanks :-)
But now szap2 doesn't work :-(
It produces an output like that on every transponder it try to tune to:
$ szap2 -a 1 "Prosieben"
zapping to 148 'ProSieben':
sat 0, frequency = 12480 MHz V, symbolrate 27500000, vpid = 0x00ff, apid = 0x0100 sid = 0x0382 (fec = -2147483648, mod = 2)
Querying info .. Delivery system=DVB-S
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'

Christian,
sorry for the delay.
two things:
- For me it is not clear that stb6100_init never gets called. Normally
it is called in dvb_frontend_init (fe->ops.tuner_ops.init).
=> Can you check (e.g. with additional printk)?
=> May be it helps to call stb6100_init in stb6100_attach.
- Second is the hint in
http://www.linuxtv.org/pipermail/linux-dvb/2007-May/017921.html to setup
gpio:
case 0x1019: // TT S2-3200 PCI
// gpio2 is connected to CLB - reset it + leave it high
saa7146_setgpio(budget_ci->budget.dev, 2, SAA7146_GPIO_OUTLO);
msleep(1);
saa7146_setgpio(budget_ci->budget.dev, 2, SAA7146_GPIO_OUTHI);
msleep(1);
budget_ci->budget.dvb_frontend = dvb_attach(stb0899_attach,
...
Hope it helps.
