In .oil file

CPU_DATA = PIC30 {    <--- Valid for any suppoeted CPU_DATA
    APP_SRC = " usrLibs/file1.c"; /* Relative path  to your project directory (the ones contains .oil file) or an absolute path */
    APP_SRC = " usrLibs/file2.c";
    ...

Is Erika using different modes like user/system/svc/irq mode in any controller? The purpose is that a Task cannot change settings like enable or disable interrupts. Yes, but only in TriCore with full AUTOSAR Memory/Service Protection Enabled*. Normally all porting runs in "supervisor mode", without...

I found a introduction to OSEK, maybe it will help to understand better the execution model (in particular TASK "Run to Completion" and multiple activation).

Paolo already responded to you according multiple TASK's activation (RUNNING max one (until the end), READY+RUNNING less or equal than "nact" (number activation) value, modifiable by TASK.ACTIVATIONS OIL filed) . Regarding the stack size I made a mistake pointing the work around for enflating the st...

As you suggested thi seems a stack corruption problem or a concurrency problem, since it doesn't happen without preemption. Wich compiler are you using? GCC? If yes, you can try to increment the default Stack Size (0xC00 bytes) with OIL CFLAGS=-D__STACK_SIZE=<number_greater_than_default_stack_size> ...

Hello, I am looking to install Erika on a prototype platform with a multicore, Aurix processor. The forum posting “About Erika Aurix Project” dated 17 Apr 2014 suggested that I should download the latest nightly build so that I had the latest functionality. However when I follow the link from the d...

Hi Alex, you are right there is a issue with the last release (I'm going to document it on the wiki too). You need to change target called by build system makefile. To do that open project properties->C/C++ Build->behaviour delete the 'all' target from Build (Incremental build). Be aware that lauter...

Hi felix, quick answers 1. WinIDEA has problems to import the *.orti file created by RT-Druid. This is because of a trailing comma in the TASK section. See the following code listing. ... I think you are right about this, the file work with Lauterbach tool probably relying to an extension of the sta...

Hi, With "you need to put compiler in path" I meant to put the compiler path in environment variable PATH. For AURIX I don't think that neither common_oil.pref will work (at least it doesn't wotk for Hightec GCC yet). If you want give a try, you can found an example of common_oil.pref file here: htt...

To select the compiler you have to modify OIL file, changing CPU_DATA container CPU_DATA = TRICORE { CPU_CLOCK = 200.0; APP_SRC = "code.c"; /* COMPILER_TYPE = GNU; Change This */ COMPILER_TYPE = TASKING; /* To this */ ... }; You can find some documentation related to ERIKA Infineon AURIX Porting her...

Ok, now the question it's more clear. Actually my question is from the definition of BCC2 class. BCC2 class defination from osek specs :--- BCC2 (like BCC1, plus more than one task per priority possible and multiple requesting of task activation allowed) Here what do we exactly mean by multiple requ...

e.guidieri

Mean to say if Erika OSEK is configured for BCC1 with basic task with SCHEDULE=FULL. Then current running task will run to complete irrespective of condiditon that high priority task is waiting for it turn. And once the current running task is completed then the execution will start as per the prio...

Example source code is available on SVN. But i did not found the source code foe Erika OSEK on SVN where exactly it is ? The Wiki page with all the information to access repository is this http://erika.tuxfamily.org/wiki/index.php?title=ERIKA_Enterprise_and_RT-Druid_SVN_Access as shortcut I add the...

I just tried MPLAB X IDE and from this is easy to create a project for debugging and editing sources, starting from an existing ELF file. So the easier way to integrate ERIKA for pic30 in a IDE is compiling from command line in Cygwin and using MPBLAB X with this kind of project. I have to say that ...

Hi maxevince, happy to have been helpful. - Removed the semaphores, used ActivateTask() instead. I would suggest to keep this method in any case: understand how to work with RTC (Run To Completition), keeps the things faster, cleaner, smaller and easier. It looks like it works with the modifications...
