Problem when loading new FPGA bitstream to X310 board

[trtam90]

Hi all,

I have a project which use X310 board. But I don't use USRP sortware for my project. I develop new FPGA system and new software for its. I have a problem when loading my FPGA bitstream to flash in X310 board.

I have used follow step to burn bitstream to flash:

1. I use Vivado, open Hardware Manage to program FPGA with "usrp_x310_fpga_HG.bit". The bit file is provided by UHD software.

2. Use UHD software (usrp_x3xx_fpga_burner.exe) to burn new FPGA bitstream to flash througth 1Gb ethernet port.

3. After waiting some minutes, I received an meassage which notify the progress is success and reset board to run new bitstream.

And below is my problem:

- When I burn new bitstream without DDR3 interface, after reset board, the bitstream is loaded successfully from flash and run normal.

- But when I burn new bitstream with DDR3 interface (use MIG 7 series IP core of Xilinx), after reset board, the bitstream is not loaded. Then I use Vivado, open Hardware Manage, and open target with Auto Connect mode, the bitstream is loaded to FPGA and run successfully.

Can you help me with this problem? I want to burn bitstream with DDR3 interface to flash and the bitstream must be loaded and run after reset board.

Thansks so much,

Tam Tran

Hello Tam,

Technical support for USRP hardware and UHD software is provided through Ettus - https://www.ettus.com/support

Vivado support would be provided directly through Xilinx - https://www.xilinx.com/support.html

The NI USRP forums are more appropriate if you are using LabVIEW, LabVIEW Communications, or the NI-USRP driver. 

Best,
