for the newcomers... another zedboard/zynq adau1761 tutorial.
all the hidden hints to build a linux web radio from scratch...
key features :
- linux vivado 2014.2 design (based upon ADI design, but with only adau1761 DAC, no hdmi, fmc,...)
- poky 1.6 linux bitbaked (learn how to add mpg123, alsa-utils, libgcc)
- ADI linux kernel & driver (specific poky recipe)
- the right .config (ext4, BLK_DEV_RAM_SIZE... UART1, ...)
- a simplified dts (avoid dtb hell and choose the right interrupt number...)
see here
hope it helps,
