content: Hi,I got a ham radio fellow who tried to get a Hermes board running from scratch. After a lot of tries the board is now assembled, all oscillators are running and all operating voltages are correct.What also worked is installing the boot loader. The next step should be to load the Hermes software into the board using Ethernet. The port LEDs flash, but apparently the adapter cannot be be "seen" fromthe PC side.Any ideas ? Jumper settings ? Some PC quirk we might have forgotten ? I am not smart enough with FPGAs, having only used PICs so far.ThanksWolfgang DL1DWG

content: For me this is the biggest source of frustration with all things that hook up to the PC you will spend hours on the hardware making sure it works and if you did everything right it ill work. Then you plug it into the computer like you did 10 other times and all of a sudden it won't work. Nothing changed it just doesn't work. Reboot and it works reboot and it doesn't work. My SDR is doing this only over USB. I tried it the other day and the computer sees that it's plugged into the USB but the SDR software, be it the flightaware or SDRUno doesn't think it's plugged in. I don't install any extra programs on this computer because I don't want things messing it up yet it still messes up on windows 10. Can all the mandatory auto updates screw with things? I have 3 usb ports all do the same thing. It used to be using a different physical USB port would fix but not this time. When that's my only hobby it kind of sucks. My eye sight is too poor at the moment to start messing around with the maze of windows settings too.

content: Thanks to all that have contributed; we are one step further now.The root casue of the problem is that the Ethernet in the Hermes has some quirks that refuse to communicate with some routers. Others work fine, as we found out.We could upload the firmware now, and basic receiver testing worked. We are now at the transmitter part, which still has (I hope solvable) problems.Thanks again !Wolfgang
