[linux-dvb] Missing LOCK with tda10045h

[Henning Glawe <glaweh@physik.fu-berlin.de>]

Moin,
for a few hours I tried now to get one of those now-so-famous Lorenzen
DVB-T card working, but I don't seem to succeed. The card is recognized,
the firmware seems to load (2.15, dll seems unchanged in 2.15a), but
after using channels.conf-dvbt-berlin as ~/.tzap/channels.conf with
tzap, I get no signal on /dev/dvb/adapter0/dvr0. 

tzap -r ProSieben
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 658000000 Hz
status 00 | signal 000b | snr 004e | ber 00000000 | unc 00000000 | 
status 00 | signal 000b | snr 005e | ber 000040f8 | unc 00000000 |

status 00 | signal 000b | snr 0033 | ber 00000000 | unc 00000000 | 
status 00 | signal 000b | snr 002a | ber 00000000 | unc 00000000 | 


Further investigations using the modules' "debug" flag give repeating
sequences of:

22:14:31 av kernel: tda10045h_write_byte: success reg=0xe, data=0x0, ret=1
22:14:31 av kernel: tda10045h_init: fw_pos=0x40
22:14:31 av kernel: tda10045h_init: fw_pos=0x80
...
22:14:34 av kernel: tda10045h_init: fw_pos=0x7740
22:14:34 av kernel: tda10045h_init: fw_pos=0x775b
22:14:34 av kernel: tda10045h_write_mask: reg=0x7, mask=0x10, data=0x0
22:14:34 av kernel: tda10045h_read_byte: reg=0x7
22:14:34 av kernel: tda10045h_read_byte: success reg=0x7, data=0x0, ret=2
22:14:34 av kernel: tda10045h_write_byte: reg=0x7, data=0x0


so it seems to upload the tda10045h firmware with each line of the tzap 
output...
