Hi,
I am using AD9081 EVM running with Xilinx KCU105(Kintex ultrascale FPGA). Design is migrated from analog device provided HDL and no-os driver for VCU118. After loading the elf file, I am getting the QPLL TX buffer underflow error, status: 0x61 on serial port.
Log file for the serial port is attached.
Kindly suggest the changes to come out this issue.
