[linux-dvb] Re: nova pci dvb-t + 2.6.0-test10 kernel?



Hello Gerd,

modprobe dvb-core dvb_shutdown_timeout=0 dvb_frontend_debug=1
modprobe tda1004x tda1004x_debug=1
modprobe budget-ci

Tries these.  Worked this time.  Strange.  Even doing a scan worked,
but only the first time.  It quickly stopped working, scan printing
I/O errors and lots of these lines in the log:

   dvb_frontend_ioctl
   dvb_bend_frequency
   dvb_frontend_set_parameters: f == 778000000, drift == 0
   dvb_frontend_internal_ioctl
   tda1004x_ioctl: cmd=0x40246f4c
   tda1004x_set_fe
   tda1004x_set_frequency
   tda1004x_enable_tuner_i2c
   tda1004x_write_mask: reg=0x7, mask=0x2, data=0x2
   tda1004x_read_byte: reg=0x7
   tda1004x_read_byte: error reg=0x7, ret=-5
   dvb_frontend_release
   dvb_frontend_internal_ioctl
   tda1004x_ioctl: cmd=0x80046f45
   tda1004x_read_status
   tda1004x_read_byte: reg=0x6
   tda1004x_read_byte: error reg=0x6, ret=-5
Looks like the tuner does not get a lock or loses sync and then starts zig-zag scanning for the frequency, but somehow this confuses the frontend and it dies...

   saa7146: register extension 'budget_ci dvb'.
   saa7146: found saa7146 @ mem ffffff000012d000 (revision 1, irq 16) (0x13c2,0x1011).
   DVB: registering new adapter (TT-Budget/WinTV-NOVA-T  PCI).
   tda1004x_attach
   tda1004x_read_byte: reg=0x0
   tda1004x_read_byte: error reg=0x0, ret=-5
   Couldn't read from EEPROM: not there?

Looks like tda1004x fails to talk to its hardware ...

This is still vanilla -test10, I'll try to update to latest cvs-kernel
now.
This should not improve things. The dvb parts did not change in between, using the "makelinks" method gives you the most up-to-date dvb driver.

Of course there is the possibility that something broke with this driver within the transition from DVB to dvb-kernel...
