Hi all, I have the problem that I am unable to write a new FGPA-image to the usrp's flash. I have a X310 with a TwinRX daughterbard, I use a Ubuntu 16.04 LTS distribution and my default UHD version is 3.11.0 but I am also able to use the UHD 4.0.0.
Because of an incorrect loaded FPGA image (a wrongly flashed XG version instead of the correct HG version - the flash process itself was not interrupted) I am unable to communicate with the USRP. I followed the X310 Device Recovery (which is decribed here: https://kb.ettus.com/X300/X310_Device_Recovery) and I was successful until I reached the step where the new image should be loaded into the flash via the uhd_image_loader tool. At this point I get a unspecific runtime error: > [INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; > UHD_3.11.0.0-release > Unit: USRP X310 (3140F8E, 10.13.17.23) > FPGA Image: > /home/bauer/sandbox/uhd-maint_2018-04-27_install_01/share/uhd/images/usrp_x310_fpga_HG.bit > failed. > Error: RuntimeError: Device reported an error during initialization. I tried to flash the USRP with UHD-3.11.00 and with UHD-4.0.0 but the behavior and error keeps the same. I am still able to load FPGA images temporarily via Vivado over the JTAG interface but these images will logically be forgotten after a power reset of the USRP. Has anybody experiences with this topic and know how this can be fixed? Is it possible to get a "true" factory reset of the USRP? Best regards Andreas
