Howdy, I think probably the first thing to do is make sure the board really is booting, and running a katcp server on port 7147.
If the board side of the connection is working, you should be able to connect to the ROACH over telnet: ``` telnet 10.42.0.226 7147 ?help ``` If this does not connect and print a list of katcp commands, then your ROACH isn't set up properly. Maybe the IP is wrong, or maybe it is not booting at all. There is some documentation at https://casper.astro.berkeley.edu/wiki/Getting_Started_with_ROACH2#ROACH2_kernel.2C_bootloader_and_romfs_upgrades , but I'm not sure it is particularly easy to follow. Probably your first step should be to connect to the ROACH board via minicom -- the serial interface is 115200,8N1. If you connect to the USB-B port then the wiki page I linked suggests that you should be able to watch the board boot by connecting to `/dev/ttyUSB2` (which I think means it is the 3rd new serial interface which will appear when you connect the board over USB. ). From here, you can watch the board boot and see if it is starting linux correctly or getting stuck somewhere.
