Steve,
To ensure MPC-718 DVB-T support can be included in the Linux kernel, I
have checked in changes to my MPC-718 development repo to:
1. extract a "firmware" sequence from the MPC-718 Windows driver
2. load that firmware in the cx18 driver to help init the MT352 on the
MPC-718
See
http://linuxtv.org/hg/~awalls/cx18-mpc718
Please test it when you can
1. Run the get_dvb_firmware script with my changes from that repo and
install the new firmware file:
$ cd cx18-mpc718
$ chmod u+x linux/Documentation/dvb/get_dvb_firmware
$ linux/Documentation/dvb/get_dvb_firmware mpc718
$ sudo cp dvb-cx18-mpc718-mt352.fw /lib/firmware (or wherever for your distro)
2. Compile, install, and test the updated cx18 driver from that repo.
Once we know it works for you, I can build a cleaned up patch set and
ask for it to be pulled to the main v4l-dvb repo.
I'd still like to fix (and have you test) the EEPROM dump after we know
the DVB-T changes are good.
Regards,
Andy
