Re: [casper] An error occurs when 'exportfs -a' is entered

For one or even a small number of ROACH2s, there probably isn't much advantage to netboot. As the number of boards in the system increases, netboot helps because everything runs the same version always. Also, with the kernel and root filesystem on an SSD, netboot is less prone to

Hello, I think nfs/netboot made sense when filesystem updates were being released for R2, but I don't really understand why anyone would use it anymore. Roach2 should soloboot by default, and unless you've compiled and are running a custom filesystem for some reason I'm not sure why any other

Hi Kaj, While I think most people on this mailing list can certainly share your frustrations with getting the toolflow to work, I think it's important to emphasize that this is an open collaboration that many contribute to without it strictly speaking being part of their critical work duties. As

Re: [casper] Different Software Versions

Hm, I have never heard about PRP cloud, what is that? I went to the web address and got to login without any further information. If this is a service that is open for all, why it is not documented? If it is not open for all, why even write about it to a public mailing list?? I am sorry but

Re: [casper] Different Software Versions

As a quick reminder to all, don't forget that the PRP cloud version of CASPER exists these days as well! (Login here: https://casper.nautilus.optiputer.net/). In addition to the normal toolflow, Vivado 2020.1 is now installed (I know that 2020.2 is recommended for RFSoC, but 2020.1 should work as

Re: [casper] Different Software Versions

Hi Kaj and Wesley, You are both right. The Python upgrades have proved a problem and it would help to list it in the documents. The requirements.txt can be too general though using versions "<" or ">". RFSOC is a new development, so I understand there could be bugs. I was more referring to the

Re: [casper] Different Software Versions

Hi Kaj, There is generally a requirements.txt in the root of the mlib_devel which should list any python dependencies and appropriate versions. I am not sure how well this is kept uptodate though. Regards Wes On Mon, Feb 21, 2022 at 1:24 PM Kaj Wiik wrote: > Hi Adam, > > I am sorry but I

Re: [casper] Different Software Versions

Hi Adam, I am sorry but I missed your reply too. The reason for us to experiment with different versions was to get RFSoC (specifically ZCU111) stuff working (by following the documentation in

[casper] Different Software Versions

Hi Casperites, I hope you are well. I have been reading the mail list and there are lots of queries about which version of Ubuntu, Python, Matlab and Simulink. We have documented this quite well on our Casper website, but I have noticed that some people try it on Windows, different versions and

Re: [casper] Simulink window does not open when Matlab is started by startsg

Hi Mitch, (cc: to our local ZCU111 group) Many thanks for reply, unfortunately I had to switch tasks and missed your mail at first. Because of that I reinstalled Ubuntu 18.04 to find that while simulink windows show up correctly, jasper_library errored with endless Python version problems.

Re: [casper] Simulink window does not open when Matlab is started by startsg

Hi Kaj, For RFSoC as long as you are using Vivado <= 2020.2 you can still use System Generator with entry started using `./startsg`. Model Composer is replacing (really just wrapping) System Generator in future releases of Vivado/Vitis >= 2021. When setting up the RFSoC in the tools I know I

Re: [casper] Simulink window does not open when Matlab is started by startsg

Hi Kaj and Jack, I am not sure if this helps or not. We use Ubuntu 18.04LTS, Vivado 2021.1 and Matlab R2019a. Sys generator is no longer available. It now uses the Xilinx add on Model Composer. Wesley created a "startmc" file to fix this. I know my startsg did not work. Try our repo:

Re: [casper] Simulink window does not open when Matlab is started by startsg

Hi, I installed kde-full but the error stays, maybe I should downgrade to 18.04... On the other hand, if that Simulink window is good enough for you, then for sure it is good enough for me :-D! I guess that error message does not affect to other functionalities... Thanks, Kaj On

I think that's pretty much what mine looks like. :) On Sat, 12 Feb 2022 at 13:08, Kaj Wiik wrote: > Hi Jack, > > It indeed might be the fastest way to follow your setup. Screenshot of the > 'simulink' window I get is attached. > > Thanks, > Kaj > > > > On 12/02/2022 14:47, Jack Hickish

Re: [casper] Simulink window does not open when Matlab is started by startsg

Hi Kaj, Not sure whether it is at all relevant, but these days when faced with any sort of probably OS/sysgen/MATLAB version combination issues I start by installing the kde-full package. I'll also add that I'm running MATLAB 2019a / Vivado 2020.2 without issue on Ubuntu 18.04. Cheers Jack On

Re: [casper] Simulink window does not open when Matlab is started by startsg

Hmm, it seems that a window *is* opened but it is totally different than the normal Simulink window (looks oldfashioned with large fonts). Still, ideas how to get the 'correct' GUI window are welcomed. Thanks, Kaj On 12/02/2022 11:35, Kaj Wiik wrote: Hi Casperites, I am trying to install

Hi Nitika The only other thing is possibly to test on a 10 bit red pitaya board because this is where the functionality was tested on (from my side). Other test environments that worked (if that might help) would be Vivado 2019.1 and Matlab R2018a. I would be interested to perform the tests
