Hi Yasir, The E320 runs Linux on the SoC of FPGA. There are devices in the FPGA which are visible to the Linux kernel, so updating the FPGA without first bringing down those devices causes problems. uhd_image_loader takes care of all this for you. You can use uhd_image_loader to first load your bitstream (the one you want to debug over JTAG), then use the Vivado hardware manager to connect to that bitstream via JTAG after it is already loaded.
