Following script is used to write table entries into the register of NetFPGA:

#!/bin/bash

${SUME_SDNET}/sw/sume/rwaxi -a 0x44020050 -w 0x11111108

${SUME_SDNET}/sw/sume/rwaxi -a 0x44020040 -w 0x00000001

But, for this operation, I need to have NetFPGA connected to the PCIe slot. If I want to operate NetFPGA in standalone mode (configure using Parallel Flash with only USB_JTAG connection), is there any alternative way to read/write register values into NetFPGA.

i.e. can we store table entries into registers of NetFPGA using the USB-JTAG port alone and with no connection to host through PCIe?

Since this issue is more relevant to P4-NetFPGA-live repository, I am closing this issue here and asking it on the other repository.
