Hi Alex Just an idea: is this problem by any chance caused by Xilinx dropping support for the OPB bus in recent ISE versions? If you look around the CASPER mailing lists, I remember this being quite a big issue around 1-2 years ago. Maybe your yellow block makes use of this bus? Regards, Si

Re: [casper] Generalising a GTX transceiver wrapper

2014-03-03 Thread Simon Scott
Hi Norbert It's been a while since I worked on transceivers, so I may be wrong when I say this, but I think that you need to generate a separate core for each transceiver on the FPGA. You can't modify a core, after you have generated it, to make it work for another transceiver. My suggestion

Hi Tim I'm not sure if you've seen this, but I found this page extremely useful in understanding how the DRAM works, in particular Laura's example ROACH design (see link at bottom of the page, under "Example Models"): https://casper.berkeley.edu/wiki/Dram Regards, Simon On 25/08/2013 14:48,

Go to https://github.com/ska-sa/roach2_nfs_uboot/ (in a web browser) and click on the "Zip" button. It downloads the repo in a zip file, via your browser. Worked perfectly for me. On 14/02/2013 10:55, David MacMahon wrote: Hi, Guy, That seems weird. Have you tried using the git protocol inst

Hi Mandana, Kim From my experiences, I have never actually seen any speed increase from enabling multithreading. But I guess it doesn't hurt to enable it anyway. Simon Scott On 05/06/2012 14:23, Kim Guzzino wrote: Mandana, The option for turning on multithreading for MAP is &q

From my experience with uBoot, you cannot ping a board running uBoot, as uBoot does not listen for pings. You can however ping a PC from the board running uBoot. On 14/05/2012 00:23, Marc Welz wrote: Hello With the Roach1 in the uboot state. Network address (192.168.3.240) acquired via dhcp

Hi Miguel With regards to your second problem: I've had a similar problem before, where I would write registers in KATCP, but when I read them back, they were all zeroes. I "fixed" this by deleting ALL the temporary and output files that Simulink generated, and recompiling the design from scr

Just to report back that I "solved" the problem. I deleted all the files that were created by Simulink/System Generator and recompiled my design from scratch, without changing anything. This seems to have solved the problem. On 09/08/2011 9:17 PM, Simon Scott wrote: Hi I hav

Hi I was wondering if there a standard byte-ordering for SPEAD packets, for example when sending a stream of 32-bit values? If so, is it little-endian or big-endian? Thanks, Simon Scott
