Components Used

Driver Development Status

  • Analog part works (Composite, SVideo and audio in)
  • Needed: I2C sniff while tuning with working driver.
  • GPIO setting of windows driver (Detected with regspy):
GPMODE:   0x80040100
GPSTATUS: 0x0655a314 (changing)

Patches

These patches are available to use the card. Both are based on latest sources from the hg-tree.

  • Driver from Zzam:

TODO: Add link to a complete patch.

  • Driver from Tino:

Patch can be downloaded from http://www.mcmilk.de/projects/dvb-card/patches/

GPIO table

List of known GPIOs.

  • GPIO 0-7: Input Parallel TS
  • GPIO 16: Input TS Valid
  • GPIO 19: Input TS Start of Packet
  • GPIO 23: Reset-PIN of demod (Setting it to input seems enough to keep demod out of reset)
  • The two output ports of the tuner (P0, P1) seem to be unusued.
