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: https://github.com/jack-h/katcp_devel/tree/master/tcpborphserver3 Cheers, Danny On 31 August 2018 at 3:37:49 am, MrIzon1234 .

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 <nivekgh...@outlook.com> wrote: > > 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 a multimeter between a power supply and the 12v input of the SNAP board. It's more of a total current draw and not the current draw of RPi since I didn't want to hack up a connector. The issue looks like an incompatible image. So, after writing Danny's image with the dd command and some failed boot's (kept getting an error of something like kernel panic but it happened so fast I didn't get to read the whole message before it shutdowns), I wrote the image on a semi-fresh SD card with etcher and booted, install casperfpga and the SNAP board programmed successfully. It would be nice to get an official image. > > Also, out of curiosity.
