According to Xilinx, the LWIP stack uses DHCP by default. But the FPGA code does set a static address. Odd.

network to PFI is shared by all, so better to recompile.
(not sure whether we can use vlan for PFI network switch)

Ugh.

But it (the controller board) is just Kintex-7 built with Vivado, so probably straightforward. The driver boards are a little more exotic, but we don't need to touch those.

I just talked with Kiaina, and we think this will not be a problem. The switch connecting to the PFI FPGA is in fact a PFS switch. So we can simply add an IP alias on the host running ics_fpsActor (and thus the ics_cobraCharmer code). 128.149.77.1 or 128.149.77.2 would be fine. The point being that no other host would see the traffic. Note, chyan

I'll leave this Open but lower the priority just so this does not disappear.

Well, it is wanted, if only to keep the switch/router interface configuration simple. Will add as 133.40.164.101, which is in the "PFI" section of the SSN-28 allocation. I.e. it will be fixed IP address, and not allocated by DHCP. With ASRD being unreachable, debugging that change could become difficult.

Merged and tagged 3.0.0 with that address, and so installable at ASRD. But after chatting a bit more, we realize that we might need to be more clever at Subaru and need to talk with Kiaina Schubert about topology.

The FPGA is plugged into the PEB Ethernet switch, so is on the same network segment as several other PFS devices: the 133.40.164.110 address in the new formware is good.
