erika aurix

Post by kanch » Tue Nov 06, 2018 10:59 am

hi,
I'm new to Erika version 2. I'm using it for Infineon AURIX TC267D and having issue regarding the timer.
1) there are various tasks in my OSTask.c like ostask_5ms(), ostask_10ms(), ostask_20ms(), etc. and it is expected that they should be called within mentioned time i.e ostask_5ms() in 5 milliseconds .
But it is observed that all these tasks are being called after 42 to 45 sec.
There is no function of 42sec or 45 sec.
can anyone help me out where the problem would possibly be?

Hi Kanch,

double posting of a misplaced topic in ERIKA3 section, I post mi answer her too, hoping that administrator will delete the wrong topic.

Said that, looking at your configuration I see that you are not using ERIKA's system timer feature (the counter COUNTER IFX_OSTASK_COUNTER is a software counter. It is not configured to be the system timer driven by an ERIKA's internal STM driver) , so the timing behaviour of the system is a responsibility left to the application.

You have to check the configuration of the Timer (STM?) that you are using to drive the system to grant the timing that you want.

Regards,
Errico

P.S. The APPMODE block is ill configured, since there is no COUNTER = HW_COUNTER; configured theonly COUNTER configured is IFX_OSTASK_COUNTER, in any case this seems to not bother the generator too much.

Hi
i have gone through the timer configuration as you said and it is working fine.
still I'm facing the same issue.
any other solution which may help me?

Probably the STM interrupt is not well configured as ISR2.

I suppose that you are working with Infineon iLLD. Infineon did ERIKA's integration with their drivers by them self do not giving us enough information to provide support for this environment. Sorry, but if this is the case you should contact Infineon directly.

For what I can see the ISR is not configured in OIL file and this would be a sure problem with a plain ERIKA's application, but from what I understood they completly bypassed our interrupt vector implementation in their integration.

Regards,
Errico

hi,

where can i get standard oil file (containing interrupts)..?

and how the alarms are configured and how does that work?

Dear Kanch,

There are a few examples for aurix in the template examples when you create a project. The "Full Demo 1" has an example of interrupts.

The OIL specification is mostly following the OSEK/VDX standard (also the alarms specification works that way).

Additional information are on those pages:

Ciao,

PJ
