Re: [casper] Roach1 Host name lookup error.

Hi Dave, Here is the configuration of the network. The host computer, a ROACH1 and a working ROACH2 running in soloboot are the only ones connected. The host is 192.168.40.1 and is offering 192.168.100.50 and the ROACH2 is assigned to 192.168.40.50. Is there anything weird about how the ROACH1

Re: [casper] Roach1 Host name lookup error.

Nothing obvious comes to mind (yet). Can you watch the roach1 boot process via serial console? What does that show? Are you using dnsmasq for the DHCP server? What if you try direct connect with mii-tool to set the speed of eth1 to 100 Mbps? Dave On May 26, 2015, at 5:00 PM, Brad Dober

Re: [casper] casperfpga on a ROACH 1 - problem with get_system_information

Hi all, For the information of anyone else who might encounter a similar problem to what I did - the NotImplementedError means that the device just wasn't implemented in casperfpga yet. In this case though it didn't really need to be because the katadc is pretty simple compared with newer

Re: [casper] Roach1 Host name lookup error.

I've switched to NFS boot to avoid SD card corruptions. However, when attempting to run netboot, the roach will send an IP discover, the host will offer one, and then the roach will send a discover again. This goes on for 10-15 times when finally the roach will request the correct IP, and the

Re: [casper] Roach1 Host name lookup error.

Are you trying to run the ROACH1 on 1 GbE? ROACH1 is not reliable on 1 GbE. You have to force it to be 100 Mbps. This can be done by using an unmanaged non-gigabit switch (or hub), a managed switch that can force its port for the ROACH1 to be 100 Mbsp only. For direct connect, you'll have

Re: [casper] Roach1 Host name lookup error.

Hi Dave, I switched to a 100 Mbps switch, and now I'm still getting the ROACH1 continuously sending DCHP discovers, and my host computer continuously sending offers, but now the occasional request/acknowledge and uboot download is no longer happening. For what it's worth, I am not using jumbo

Re: [casper] Roach1 Host name lookup error.

Weird. Are there any other hosts on the network that might be also sending (non-netboot-aware) DHCP offers? What does sudo tcpdump -i eth0 -n -e -v port bootps or port bootpc show (replacing eth0 with the actual network interface name where the DHCP activity is). Dave On May 26, 2015, at
