From b206f8f37a8fc18c6539adae7335596df08c998c Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 24 Mar 2017 18:19:05 +0100 Subject: [PATCH] m2k: Disable AD9963 core RX datapath again The RX datapath has a lot of things (IQ correction, DC filter, ...) that take up a lot of space which are all not really needed in this project. So disable the RX datapath. It was previously enabled because the ad9963 core did not perform sign-extension on the ADC data signal when the datapath was disabled. But this has now been addressed.
