Sorry for the delay. Can you please post the part number for your board? On some of our older boards there was a problem with the USB_ID pin on the OTG connector. Let's make sure that's not the issue.

You can configure ssh keys to allow transfers without having to type a password in, if you need it.

Just hit a key and break and load the code manually?
If you want the FPGA to be loaded, then we often make a separate script for loading the fpga, e.g:

for 1000 full/half duplex), then DHCP will work in uboot. I'm still looking into DHCP at gig settings.
