Hi, I am trying to get SAI to work on a mx6sx sdb board. Here are the changes I made: http://pastebin.com/aq32B24v I can see the driver getting probed: [ 2.198276] fsl-asoc-card sound: wm8962 <-> 21d4000.sai mapping ok ,but when attempting a playback it fails: $ aplay clarinet.wav [ 110.843619] fsl-sai 21d4000.sai: isr: Transmit underrun detected [ 110.849841] fsl-sai 21d4000.sai: isr: Transmit underrun detected [ 110.855995] fsl-sai 21d4000.sai: isr: Transmit underrun detected (repeats forever). Any ideas as to how to get SAI working on this platform? Zidan, How have you tested SAI when you usptream the driver?
