tcpborphserver is a server designed to control roaches. It speaks KATCP over port 7147. There are three versions of tcpborphserver at the moment. ps; however i dont have a clue on what that means :) On Thu, Aug 30, 2018 at 3:19 AM Nivek Ghazi wrote: > > Hi Wesley, Danny, > > It don't think its

Yep, it's the process on the RPi that configures the FPGA and responds to requests from casperfpga. The tcpborphserver starts up as a daemon when the RPi boots (this is setup via linux's upstart service), after which it listens for commands over the Ethernet port. The code is here:

I can't say I've seen this particular behaviour before. We did have issues with ROACH1s turning themselves on or off with ESD (touch the case, or plug a cable in/out and the board would turn on/off). That was fixed with proper grounding. Jason > On 29 Aug 2018, at 18:42, Jonathon Kocz

Hi Wesley, Danny, It don't think its was a power issue as the RPi 3b+ was getting its power from the 40 pin connection to the SNAP board. I measured the current draw to be around 1.1A at idle when using a RPi 3b and around 1.8A when running firmware. These measurements were made by connecting

Sounds like you do have the official image I'll upload it to the wiki! tcpborphserver is a server which runs on the RPI and speaks katcp (the protocol the roaches use). It basically receives katcp read/write/program commands over a TCP socket and then actions them on the FPGA using the chip's
