Re: [casper] KATADC attenuators
Hi Tom, Not sure if you have resolved this, but there is no jumper setting to override the attenuation on the KatADC. There are jumpers (J2, 3) that force the input switches (U30, 31) on for test purposes. -F On Thu, Dec 20, 2012 at 10:57 PM, Tom Kuiper kui...@jpl.nasa.gov wrote: I have two KATADCs, one each in ZDOC0 of two ROACH-1 boards (named roach1 and roach2). It appears that the attenuator for input 0 of the KATADC in roach2 is at 0 dB for whatever attenuation setting command is sent to it. The other three inputs respond as I expect. I assume that this is some kind of hardware failure but I thought I'd better check if there was some jumper setting or control bit that I don't know about.

[casper] 1Gbe Correlator
hi, It is possible to generate a correlator with data otuput through 1Gbit RJ45 Ethernet? We have 1 ROACH and 1 computer with no 10Gbe. -- Atte. Arturo
Re: [casper] 1Gbe Correlator
Hi Arturo It is possible to generate a correlator with data otuput through 1Gbit RJ45 Ethernet? We have 1 ROACH and 1 computer with no 10Gbe. It is possible. You can write some software on the computer (look at the python CORR package) that checks to see when the accumulator is done, copies the data from the accumulator, and outputs/processes it in some way. The only problem with this approach is that it is slow. You will have to accumulate for a long time (seconds) to be able to leave enough time to copy all the data from the accumulator and output it. The first generation ROACH boards ethernet connections are also only guaranteed to work at 100Mb/s due to issues with the ethernet module. This will make your system even slower. However, if this slowness is not a problem then this is the cheapest and easiest option. Regards Andrew
Re: [casper] 1Gbe Correlator
Thanks, then in the meantime I'll be doing the tutorials and changing the outdated blocks when will be necessary. Any problem it will be report in the mail list. 2013/1/16 Jason Manley jman...@ska.ac.za It _might_ work out the box. Next week we'll be updating the tutorials to work on Matlab 2012b and Xilinx 14.3, so then it should definitely work. Until then, you might just need to replace some of the outdated blocks (the pfb_fir and fft_wideband_real, for example, come to mind). In any event, you should be able to open the design and look at it; it might just not simulate or build properly. The control software should work fine as-is.

[casper] Problem with dram block using mlib_devel
Hello,
I am a new user of the Casper/Roach.
I am using Matlab 2012a, Xilinx 14.2, and the latest mlib_devel libraries.
With this setup I have been able to compile tutorials 1-4.
I had to update a few blocks here and there to get them to compile.
If I try to compile anything with a dram block I get the error below.
In this case I am using Jason Manley's DRAM counter example from the dram wiki
page.
I have updated the dram block from the latest (Jan 13, 2012) library I have
installed.
Anyone have any ideas on what the problem maybe?

Re: [casper] Problem with dram block using mlib_devel
It looks like the simulation block's broken. If you're not trying to simulate
it, you could just delete it (look under the DRAM mask and remove all
sim_wrapper stuff) and recompile. Otherwise, you should try'n fix the broken
link.
