I would like to use some of the same methods I learned in the casper tutorial: https://casper.berkeley.edu/wiki/Introduction_to_Simulink on roach 2, including finding the pid of my bof process and navigating to it's proc directory. However, though this works on roach 1, on roach 2 I can't

Re: [casper] KatADC vs ASIAA ADC

-8. Can it go to 3.2 GS/s? Or are you using the ASIAA ADC? We switched mid-stream to the ASIAA ADC. It's faster, cheaper, and has better performance. John Thanks! Gopal On Fri, Mar 21, 2014 at 1:30 PM, John Ford jf...@nrao.edu wrote: Hi Dan Thanks for your input. For 800 MHz BW

Re: [casper] ROACH-2 USB Communication Dead?

Hi all, We've been trying to get the serial link between the ROACH-2 and a PC, and we haven't had any success at all. These are the cable configurations we've tried: 1. USB-A Male (ROACH)/USB-A Male (PC) 2. USB-A Male (ROACH)/USB-Serial Adapter/DB9 Female (PC) 3. RS232 Pin Headers

Re: [casper] Bracket for ROACH iStar D-107 enclosure

Hi all, I have some ROACHes mounted in a standard 19 rack enclosure; they are packaged in the usual iStar D-107 1.3U rack-mount chassis. However, only the front panel of the D-107 chassis is bolted to the rack enclosure; the rear end of the chassis hangs down as shown in the attached photo.

Re: [casper] 100-Gb-E NIC Cards and switches

Hi Kris, Mellanox's 40-gE SX10## series (expandable to 56 Gb/s) has worked for LEDA w/ no pain. Does you app. preclude using twice as many links of 56 Gb/s? Cisco's 1 port 100 Gb/s Ethernet module for their switch is $71,500. :) I think sticking with 40 Gb/s is the thing for now. Even

Re: [casper] 10gb ethernet configuration

*Hi Casperians,I have trouble to configure the 10gb ethernet to work on roach2. The 10gb port (sfp+) is connected to a PC where the file system of roach2 is mounted. I can use the DHCP server to configure the ip of roach2 ppc, but don't know how to configure the ip address (or interface?)

[casper] URSI meeting next week

Hi all Are any of my fellow Casperites going to URSI next week? I have a presentation in Commission J on Wednesday. Does anyone else have a presentation involving CASPER stuff? Maybe we can get together some night and elect an offical CASPER microbrew. :) John

Re: [casper] question about roach2 netboot

*Dear Casperian,I met a problem when I netboot roach2-rev2 board. The modprobe files in the debian_stable_devel folder are missing. I can only run some simple scrip via minicom. The server used to control roach2 is an CenOS system, not Debian, but I was able to install all tool kits required

Another problem I have seen is if you have your own version of cygwin installed, it can conflict with the ISE cygwin. Hi John I change the direction of my files, but the problem still remains. I'll try to find something on the web. Best Regards Rolando Paz 2013/12/7 John Ford jf
