Re: [casper] Matlab crashes with tutorial 3
Well, you wouldn't want things to be too easy now, would you? :) Your missing pcore problem occurs because you are compiling with ISE 13.3, which removed support for some of the cores that we still use. The design should compile fine with 11.x (which is what I tested it on), but you can fix the error relatively easily -- see https://casper.berkeley.edu/wiki/CASPER_With_ISE_13.1 Hopefully that will be the only hurdle, Jack On 10 May 2012 15:05, Gopal Narayanan go...@astro.umass.edu wrote: Compilation of the MDL file for tutorial 3 in Jack's git repository failed.

John Hey Gopal, One thing you can try is to start matlab without loading the yellow blocks, open the model file and add them in fresh from the library, save and return to normal usage. This will require you comment out the load xps_library portion of your matlab startup script. Start matlab, and open the desired model file.

You may need to consult the tutorial, or look at the original model .mdl file in a text editor, to make sure you set the parameters appropriately. From there you should be able to save the .mdl file, close matlab, go back to the startup file and uncomment back to the regular usage. Hopefully it opens up fine this time.

Re: [casper] Matlab crashes with tutorial 3
Hi Jack, Thanks to you and Danny Price for suggesting this. I copied over the pcores in the zip file mentioned in the CASPER wiki to my mlib_devel/xps_lib/XPS_ROACH_base/pcores directory, then I deleted the previous r_spec_2048_r106 build directory, and then ran the compile again.

Re: [casper] Matlab crashes with tutorial 3
Hi Laura, Thank you for your suggestions. I made progress with your suggestions, but there are still some problems. I commented out the xps_library portion of my matlab startup script. Indeed, now I am able to open the tutorial 3 model file without a segfault. I see the yellow blocks show up as bad links. I can delete them. I looked at the original .mdl file in a text editor and saw what I need to add. I addpath the xps_library area to the matlab path. This next step took me a while to figure out (maybe it is obvious to others). Inside the simulink library browser I had to go to View-Refresh Tree View (or F5) to have simulink catch the newly added xps_library. I add appropriate yellow blocks. I can save this new model file. But when I edit back the xps_library into the startup script and restart sysgen, and open the newly saved tutorial 3 file, I segfault again! So I decide it is a pain in the neck, but I can go through adding the xps_library path by hand each time to be able to open this model. So I commented out the xps_library in startup, manually addpath and refresh tree view after opening model. The model is all there now. So I want to compile the model, and I run bee_xps, and press the Run XPS button, it fails with the following message: Detected Linux OS Warning: The fourth output, VERSN, of FILEPARTS will be removed in a future release. In fileparts at 35 In gen_xps_files at 121 In bee_xpsrun_Callback at 150 In bee_xps at 82 # ## System Update ## # config = source: @pipeline_init_xblock config = source: @pipeline_init_xblock config = source: @pipeline_init_xblock config = source: @pipeline_init_xblock config = source: @pipeline_init_xblock Error using == gen_xps_files at 199 Error due to multiple causes.

Re: [casper] Matlab crashes with tutorial 3
Hey Gopal, One thing you can try is to start matlab without loading the yellow blocks, open the model file and add them in fresh from the library, save and return to normal usage. This will require you comment out the load xps_library portion of your matlab startup script. Start matlab, and open the desired model file. Doing this, you may be able to see the yellow blocks show up as bad links with red dashes around them. From there you can delete them, and manually add them back in from the xps library. You may need to consult the tutorial, or look at the original model .mdl file in a text editor, to make sure you set the parameters appropriately. From there you should be able to save the .mdl file, close matlab, go back to the startup file and uncomment back to the regular usage. Hopefully it opens up fine this time. If this solution works, perhaps I can write something more detailed to the wiki page for the Tutorials. Would that be an appropriate edit for the wiki? I think something stated on that page would help - we have seen several new roach users encounter this issue. Gopal, I was also strongly advised when I started out to use 11.5 and the stable release of the tools. This solution fixed the problem on that setup, hopefully it does on 13 as well. --Laura On Mon, May 7, 2012 at 12:44 PM, Gopal Narayanan go...@astro.umass.eduwrote: Hello All, I am running Matlab R2011A on a 64-bit Debian Linux System.
