[casper] BEE2

Dear all, does anyone have a BEE2 they would like to sell/rent? Kris

[casper] BEE2 hanging

Hi all. We're working hard on cleaning up our 800 MHz Coherent Dedispersion pulsar machine for production. We have it working with 8 GPU machines, and from 64 to 2048 coarse channels. One problem we have is that with our output FPGA that rearranges the data and ships it off simultaneously over 4

[casper] BEE2 enclosure

Hi everyone, Does anyone have an off-the-shelf solution for a rack-mountable BEE2 case? Thanks, Laura

[casper] BEE2 eeprom

Hi all. Is there any way to get the eeprom contents while the bee2 is running linux? Like the get_eeprom command, only from a borph linux shell. John

[casper] BEE2 Build Times

All, As some of you know, Randy and I have been recently working on trying to get the interchip connections to work properly, utilizing the packed registers, phase delays, etc to get synchronized data into FPGA2. We have a question regarding the build times for BEE2 designs that use these in

[casper] BEE2 Center FPGA

Hello, My BEE2 is going to be deployed remotely. I need to use the Center FPGA for my designs. Is there any way to remotely reprogram the Center FPGA (without having to physically remove the CF card and put it in a card reader?) Can I just program the new bit file using the JTAG header or will that

Re: [casper] BEE2 hanging

Hi John, Are you running this arm() command on the BEE2 or are you using a udp or tcp server? Does it write the value in ascii or binary mode? BORPH has occasionally acted strangely for us when we use ascii mode so we don't use it anymore. Mark On Fri, Jan 29, 2010 at 1:23 PM, John Ford wrote

[casper] BEE2 mechanical drawing?

All, Does anyone have a mechanical drawing that depicts the dimensions of the BEE2 mounting holes? Thanks, Jason

Re: [casper] BEE2 Build Times

I haven't had exactly this problem, but I have had designs meet timing and then changing just the slightest thing makes it miss timing by a lot. I think the place and route is sort of heuristic, so just by chance it gets an easy job some days and other days it spends hours going in the wrong direct

Re: [casper] BEE2 Build Times

Like Glenn has said, different routing within the FPGA can cause a significant increase in the time needed to PAR. The IOBs for the interchip links are pretty distributed through the chip, so changing the target can make it harder to route. You can check the PAR logs (system.log or implementation

[casper] BEE2 Available for Acquisition

All, LBL has just received a BEE2 system that due to the 11 month delay in delivery and subsequent acquisition of a BEE3 we no longer need. The system arrived in good condition but has not been powered. If anyone has an interest in acquiring this system, please let me know. Thanks, Dave

Re: [casper] BEE2 for sale

Dan, When I offered up the PAPER BEE2's, you expressed interest. There are now those, the one from LBNL (~$10k) and the whizz one. There's a v.likely $385k coming from USAF to ATA and 3rd beamformer desired. They can thus use 5 and a spare makes sense, particularly if they can be purchased at ~$1

Re: [casper] BEE2 Center FPGA

Hi Glenn, The .ace file is Linux-accessible at /cfgs. You can overwrite it from within BORPH, then do a software reboot to load the new bitstream. Thanks, Henry G Jones wrote: Hello, My BEE2 is going to be deployed remotely. I need to use the Center FPGA for my designs. Is there any way to re

Thanks Dan. That worked really well. Once the chassis is built to verify my drawing is correct, I'll make it available to everyone. Thanks again, Jason At 11:04 AM 12/20/2010, drbu...@berkeley.edu wrote: The fastest way to get those numbers is to open the Allegro PCB file and use the line

Re: [casper] [bee2-users] [Fwd: IBOB's ADC]

Hi Shilpa and Glen, The casper list is probably more appropriate (or at least more useful) for this discussion, since the Parkes spectrometer is a CASPER design. I have run into similar problems where a small design change makes the design not route properly or meet timing. I'm not sure what the so

[casper] BEE2 with a misbehaving internal PSU

Hi, In case there are BEE2 users who don't follow the BEE2 mailing lists... Matt Dexter -- Forwarded message -- Date: Mon, 5 Mar 2012 16:56:46 -0800 (PST) From: Matt Dexter To: BEE2 Users Cc: bee2-maintain...@lists.berkeley.edu Subject: Re: [bee2-users] BEE2 with a misbehavin

Re: [casper] BEE2 with a misbehaving internal PSU

Hi Matt. We've had failure of the connections at the BEE2 board itself. The connectors lose their spring and oxidize. We just soldered the wires on instead of changing the connectors. For us the symptom was that the bee2 would boot up fine, but would fail once a few of the FPGAs were loaded up

Re: [casper] [bee2-users] Difficulty meeting timing with DRAM in ISE 10.1

Greg, Perhaps a CASPER maintainer can correct me if I'm wrong, but I believe I am using the black box, because the files used are .ngo files. There is also a "black box definition" bbd file. The pcore is called ddr2_controller_v2_00_a if that helps any. Thanks, Glenn On Mon, Sep 8, 2008 at 7:29 AM

Re: [casper] [bee2-users] Hang issue when trying to wr/rd a register

Closer, but still not there yet... :-( With the dcm_module version change I described earlier, the bof file loads and I get a tinysh prompt instead of hanging (progress!). I can read and write my registers as expected (so far) in tinysh (progress!). My BORPH reads and writes via the /proc
