Hello Martin,
I hope I am replying now correctly (I am using reply all to you and mailing
list).
I am still not able to flash RFNoC bit stream on FPGA. Here is what I am doing:
1. First step - Check status of device
Call: uhd_usrp_probe
Output: [INFO] [X300] Using LVBITX bitfile
/home/cas-sdr/rfnoc/share/uhd/images/usrp_x310_fpga_XG.lvbitx...
...
| | | RFNoC blocks on this device:
| | |
| | | * DmaFIFO_0
| | | * Radio_0
| | | * Radio_1
| | | * DDC_0
| | | * DDC_1
| | | * DUC_0
| | | * DUC_1
2. Second step: Load new FPGA image - usrp_x310_fpga_RFNOC_XG.lvbitx:
Call: uhd_image_loader
--args="type=x300,RESOURCES=RIO0" --fpga-path="/xyz/xyz/rfnoc/share/uhd/images
/usrp_x310_fpga_RFNOC_XG.lvbitx"
Output:
[INFO] [UHDlinux; GNU C++ version 4.8.4;
Boost_105400; UHD_4.0.0.rfnoc-devel-409-gec9138eb]

Unit: USRP X310 (3114FC4, RIO0)
FPGA Image:
/xyz/xyz/rfnoc/share/uhd/images/usrp_x310_fpga_RFNOC_XG.lvbitx
-- Loading XG FPGA image (this will take 5-10
minutes)...[INFO] [NIRIO] rpc_client stopping...
[INFO] [NIRIO] rpc_client stopped.
....After few minutes I get:
successful.
Power-cycle the USRP X310 to use the new
image.
[INFO] [NIRIO] rpc_client stopping...
[INFO] [NIRIO] rpc_client stopped.
3. Third step: power cycle USRP and PC
Call: sudo /usr/local/bin/niusrprio_pcie stop
Power cycle USRP
Power cycle PC
4. Forth step: power up USRP and PC, check status of USRP
Call: Power UP USRP
Power UP PC
uhd_usrp_probe
Output: [INFO] [X300] Using LVBITX bitfile
/home/cas-sdr/rfnoc/share/uhd/images/usrp_x310_fpga_XG.lvbitx...

So, what I am doing wrong?
In general I would like to ask you do suggest usage of PCIe or 10GBe interface
with USRP X series?
In terms of throughput between PC and USRP, PCIe and 2x 10GBe interface should
be same or I am wrong?
I am asking this because I am working with UWB sampling and compressed sampling
(high throughput is important, especially for Rx side)
My configuration of USRP consists of 2 UBX cards together with X310.
Maybe I can try to flash usrp_x310_fpga_RFNOC_XG.lvbitx over jtag with Xilinx
tools. However, I do not think .lvbitx is supported with xilinx tools.
Thanks once again,
Kind Regards,
Tarik

Tarik,
please remember to keep responses on the mailing list, lest they get lost.
Yeah, just add fpga=/path/to/image.lvbitx to your device args.
