Problem with two budget-ci dvb-t cards

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I posted this to the vdr list originally, but since it's obviously a
kernel level problem I'm asking here too. :)

I have two budget cards. Both are handled with budget-ci driver, although
only one of them actually has the physical CI connector..

Cards are quite similar. Older card has saa7146 and tda10045, and newer
card has saa7146 and tda10046.. So slightly different frontend chips.

Either card works fine if plugged in alone, but if both are plugged in,
only the tda10046 card works. I have tried them in every slot in all
possible combinations, and it's always the same.

I tried to tune channels with "tzap". Both cards "work" fine, but only
tda10046 card ever reports FE_HAS_LOCK.. Tda10045 card never shows
FE_HAS_LOCK and reports very high ber numbers. Just like if the antenna
was unplugged, but it isn't. :)

Is it possible that there is some bug that prevents using tda10045 and
tda10046 in the same system? They both use the same tda1004x module after
all.. Anyone with such system?

Here's dmesg output when initializing the cards. Looks fine, right?
