ad9680 configuration for fmcdaq2 w/ zc706

Hi

 

I'm trying to do a fast bringup of xilinx zynq zc706 with the adi fmcdaq2. I tried the bare metal reference design, but the deafult configuration doesn't work. I keep getting :

AD9680 PLL is unlocked.

JESD204B-GT-RX[3]: Invalid status, received(0x0FFFF), expected(0x1FFFF)!

JESD204B-GT-RX[2]: Invalid status, received(0x0FFFF), expected(0x1FFFF)!

JESD204B-GT-RX[1]: Invalid status, received(0x0FFFF), expected(0x1FFFF)!

JESD204B-GT-RX[0]: Invalid status, received(0x0FFFF), expected(0x1FFFF)!

I tried to copy the configuration from the linux kernel but still no success.

 

When the PLL is unlocked, the JESD communication fails, and I don't get any samples in the ad9680 a2d.

 

Where can I find a working configuration reference design?

What else could be the problem?

 

Thanks a lot,

Pavel
