Any pointers how to debug this further? This is with the latest media_build from linuxtv.org on 3.17.4.
Looks like si2168 firmware failed to download, but si2157 succeeded. Could you add some more time for driver timeout? Current timeout is selected by trial and error, lets say it takes always max 43ms for my device I coded it 50ms.
drivers/media/dvb-frontends/si2168.c /* wait cmd execution terminate */ #define TIMEOUT 50 change it to #define TIMEOUT 500 Also, if it does not work, could you enable debugs to see what happens? rmmod si2168 modprobe si2168 echo -n 'module si2168 =pft' > /sys/kernel/debug/dynamic_debug/control regards Antti -- http://palosaari.fi/ -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
