I have switched from hack to zl10353 module, and I have tested more different setups. I have found what wrong is, in function tl10353_read_status() and zl10353_read_snr(), not positive value. zl10353_read_status() reg has digital hasn't digital 0x05 0x40 0x00 0x06 0x00 0x21 0x07 0x33 0x03 0x08 0x00 0x00 more than 0x00 0x09 0x58 0x00 zl10353_read_snr() reg has digital hasn't digital 0x0f 0x28 inv ( 0xd8) =^87% 0x2b inv (0xd5) =^ 84% 0x10 0x00 0x00 the function set_parameters is working. I have added (only for test) a full HAS_FE_* status, so that I tested the set_parameter function. -- Stefan Ringel <stefan.ringel@xxxxxxxx> -- 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
