I have a Simulink Real-Time Desktop model that launches from a GUIDE application in External mode. My problem is how to run the model without Matlab rebuilding it every single time.
In the _OpeningFcn I included a 'rtwrebuild' command with the expectation that this would rebuild the code only if the model had been changed since the last run. However, when I start the real-time simulation using set_param(MODEL, 'SimulationCommand', 'start', ...), it invariably rebuilds the code regardless of what 'rtwrebuild' did. How can I keep the start command from causing all these unnecessary builds?
Since I don't have reputation enough for posting a comment request for clarification, I'll ask it here; did you check the rebuild option setting in the configuration set?
From my own experience it take a long time even if set to only rebuild if changes detected because it still opens every single file in the model tree to check that nothing was changed. Also I think some parameter changes counts as cause for rebuild. If you don't want that you need to set "Never" rebuild and control this yourself.

I have just started to work in a project where the product uses a imx8m mini module together with Yocto Linux (Zeus).
Currently we have a problem related to the shutdown behavior of the product, and we need to modify what happens during a shutdown.
As today when we shutdown or a thermal emergency happens, the PMIC_ON_REQ(That controls the external power regulator) goes low, but we need to change this behavior that it keeps the current value on PMIC_ON_REQ, as we have other diagnostic devices that needs to talk to the PMIC after that the imx8mm has turned off. In other words: I want to keep the value of the gpio as long as possible, until the control is out of reach.
But my current problem is that I don't know where to start, or what kernel module I shall look into.
Does any one have any clue where I shall start to look to be able to find the code for patching?
I have tried commands in devtool like "devtool modify power/thermal/soc" but without finding the needed code..
Please observe that this is my first Yocto project ever, so if I write something strange, bare with me
When running my code in debug mode, I keep getting 2 error messages:
Could not delete [path_to]\productiondb.log. May be locked by another process
I don't know what process might be locking it. It comes when I make changes to the code while my Pivotal tc Server is running in debug mode, but it dosent seem to create a lot's of trouble. Sometimes however, I get this warning:
Also due to some changes. I usally just restart the server and move on. This isen't the real problem, the real problem is that I get these messages when I havent doen any changes. Somethimes it accures when I run a certen part of the code, other times i occurs when I open certen codes in sts, however, it doen't seem to stop at the same place twice.
I am suspecting that this has something to do with git. I am using git to change between versions and doing tests. So I am thinking that STS has some of the code in memory from before I changed branche with git, and isen't updating it before I run or open the file with that code. But I am rather new to both sts and git, and can't be certan that it would work that way. If it is, does anyone know how to update sts after I have changed branch? If it is not, does anyone know what might causing it?
If you run an app in debug mode, the Eclipse Debugger tells the application when code gets changed and tries to use the debug API to swap in the new code into the running application. This is especially useful if you debug your code, hit a breakpoint, step through the code, fit the issue, change the code, and press save. At that moment, the Eclipse compiler updates the class file and tells the running JVM to swap in the new code. If that succeeds, the debugger will jump back to the last stack frame and the execution of your app will continue with the beginning of the method that you entered. This allows you to directly continue to debug and step through the updated code without restarting the app.
While this is a great feature of the JVM, it is very limited in terms of what scope of changes to the classes the JVM can deal with while doing this hot-swap. It is usually limited to method implementations. So adding new methods, adding or deleting members of the class, etc, are not supported. As a result, the above screenshot will appear. It means that the JVM wasn't able to hot-swap the changed code and will continue to run with the previously loaded code instead of the changed one.
I am working through the tutorial files included with the ACT-R Standalone Windows distribution. This isn't part of any academics assignment; I'm working on this to learn cognitive modeling and writing production systems. I am using Lispbox, an EMACS-SLIME-LISP bundle to write my cognitive models. The distro and lispbox reside on my flash drive. Finally, the distro uses Clozure Common Lisp.
The problem is that whenever I try to reload a model after making changes, ACT-R gives me this error:
Error Reloading:
#|warning: no load file recorded |#
#|warning: cannot use reload |#
It only does this for my unit 2 assignment model. Not any other model, including the one I have written in unit 1.
Now this is a big issue for me - instead of simply pressing "reload" on ACT-R's GUI, I'm forced to close ACT-R entirely and open it again every time I want to reload the model.
I'm thinking this is a problem with EMACS. I have tried reinstalling ACT-R, and deleting any .lisp~ files or anything else that Emacs has saved in addition to the file I wrote. I still get this error.
Could you please help me understand what's going on and how I can fix this if it ever arises again in the future? I would like to get back to working on my assignment as soon as possible.
I have emailed the creator of ACT-R; He told me that I must include the statement
(clear all)
at the beginning of every file, so the software uses the most up-to-date file when reloading.
I have activated an option "Build on resource save". My typing habits is to save the code every few seconds and whenever previous build is not complete before I save again, I get a window like this:
Basically Eclipse is forcing me to wait before it will finish the previous build and start a new one. Can I somehow configure it, so that it will start new build automatically once the previous is completed and will not block my input? It is okay if it will incorporate multiple consequent saves of the code.
Essentially, my solution was not to build on save. As scottb mentioned in comments it is too complicated to actually decide when it is save to build and when it is not.
I would like to know how it's possible to run a integrity test without starting it in background. So I want to run it in foreground and wait until it's finished.
The following runs on background (http://docs.intersystems.com/cache20071/csp/docbook/DocBook.UI.Page.cls?KEY=GSA_manage):
Do Silent^Integrity("/tmp/logfile")
I also can't find the routine of ^Integrity (in %SYS). How may I see the code?
Using Caché Intersystems 2008.
Thanks by advance,
In the %SYS namespace, you can run ^Integrity directly without providing a tag name, e.g.:
> Do ^Integrity
You should be able to view the source code in Cache Studio in your version, assuming you are in the %SYS namespace. I can pull it up fine in Cache 2010, though I understand that Intersystems has stopped providing the underlying source for much of their standard codebase in more recent versions. If, in fact, you don't have the source for ^Integrity available on your system, you'll simply have to contact them for any information you need beyond what the documentation provides.
