Hello. I am using uhd 3.15 on the usrp e310 board. I want to run gr-phosphor but when flashing FPGA using uhd_image_loader --args type = e3xx --fpga-path / home / adray / rfnoc / src / uhd / fpga-src / usrp3 / top / e300 / build-E310_RFNOC_sg3 / e300.bit which is created by version uhd 3.14.1 and uhd_image_builder_gui.py the following message is displayed uhd_image_loader --args type = e3xx --fpga-path /home/adray/rfnoc/src/uhd/fpga-src/usrp3/top/e300/build-E310_RFNOC_sg3/e300.bit [INFO] [UHD] linux; GNU C ++ version 7.5.0; Boost_106501; UHD_3.15.0.HEAD-0-gaea0e2de [INFO] [MPMD] Initializing 1 device (s) in parallel with args: mgmt_addr = 192.168.10.2, type = e3xx, product = e310_sg3, serial = 31370CF, claimed = False, reachable = No, skip_init = 1 Error: rpc :: timeout: Timeout of 10000ms while calling RPC function 'claim and then when uhd_find_devices is output, I see this -------------------------------------------------- - UHD Device 0 -------------------------------------------------- Device Address: serial: claimed: False mgmt_addr: 192.168.10.2 product: reachable: No type
