Using the OM5776 eval board, and using the algorithm published in the rev 1.1.0 datasheet, I find I am getting an I2C NAK, which does not go away and requires a chip reset to restore any I2C communication, after successfully writing EP4 (r06) in the 'image rejection cal pt I, wanted signal measurement' section where registers are written back. (NAK occurs on write to EP5) Anyone with better experience ? Thanks, MikeW _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
