Hi, I have found an issue with the Interrupt Vector Table, which can lead to wrong entry address calculations, because the TriCore needs the Interrupt Vector Table to be aligned to addresses where Bits [12:5] are 0. In the TriCore´s architecture manual (vol1) you can find a more detailed discription...

Thank you for your patience, Each service needed by IOC implementation SHALL be transparently granted to each OS-Application that use IOC by the configurator, so to emulate this just follow b) I understand that each OS-Application using IOC needs access to the services that are used by the IOC, if I...

yes, they are .... here you can find some information about this project http://www.edas-ev.eu/.

Hi Errico, I have integrated parts of this example \examples\tricore\tc2Yx\as_multicore_examples\08_IOC_save_non_primitive_unqueued now in my application and I have faced some problems with the IOC prototype if Memory and and Service Protection are enabled. That is the the read-inlinefunction which ...

I don´t know if it´s safer. I want to avoid that issue (from your wiki): (5) to manipulate Operating System objects that belong to another OS-Application (to which it does not have the necessary permissions), e.g. an OS-Application tries to execute ActivateTask() on a task it does not own. TaskMaste...

ok, I will then use the shared memory section for the communication between the two Tasks.

Thank you again for your help Errico.

yes, the requirement is from 4.2.1. and the old requirement explains the behavior I have observed.

In which state is ERIKA currently? Is ERIKA synchronous with 4.2.1 (except sws_os_00266) and do you plan to implement the changes?

Thank you for your support :)

Hi again, I have the following configuration: -MCU is TriCore TC275 B-Step -3 OS-Applications: AppCore0 (trusted) on Core0. AppCore1 (untrusted) and AppCore1_t (trusted) on Core1. -I have one Event assigned to TaskMaster that belongs to AppCore0. ACCESSING_APPLICATION of TaskMaster is AppCore1_t. -A...

thank you for your reply. I´m currently not interested in commercial support, because I am working with ERIKA in a non-commercial domain. I´m writing a master thesis about TriCore´s safety features and therefore it would be nice to have a demonstrator that utilizes the code protection of the TriCore...

Hi, in AUTOSAR (sws_os_00027) code protection is optional and in ERIKA 2.5.0 it is not implemented yet (all code is executable). I have seen now a "todo" for the code protection in 'ee_tc_mem_time_prot.c'. Do you have concrete plans to implement code protection in the near future or does it have a l...
