RTOS and DMA [S32K144]

electronica2pow — Mon, 09 Apr 2018 11:52:45 GMT

Hi to the community,

I am trying to create a RTOS application using the S32K144 platform. I would like to know if there is some examples availables in order to program a RTOS system.

On the other hand, i was reading the programming cookbook, but i would like to know if there are another examples using DMA.

Thanks,

Jorge

Hi,
There is only the SDK FreeRTOS demo app.

Regarding DMA, you may refer to below examples.

Example S32K144 PDB ADC trigger DMA ISR S32DS

Example S32K144 DMA memory copy test S32DS

Hi Daniel,

You are right, but this example was programmed using a different syntax. I tried to compile it, but it doesn't work. I realised that some of the examples were programmed using a new syntax and some of them with an old one using different libraries and configuring the platform in a different way. So, is there any RTOS example using the new syntax? It could be just the same example.

Regards,

Jorge

Hi Jorge,
Sorry for the delay.
Could you explain what you mean by the new and old syntax and specify your SDK version, S32K144 mask-set and which example can you not compile?

Thanks,
Daniel

Hi daniel,

I mean that i use these examples:

Not these ones:

They use different libraries like cpu.h and basic C libraries. While i am using just s32k144.h library. The functions used on each type are different and you must add a processor in order to compile your code, while i am not doing anything of that.

S32 Design Studio for ARM

Version: 2018.R1
Build id: 180320

About the board: it is a S32K144 EVB-Q100.

I want to find a RTOS example.

About the syntax:

What i use.

What is used for the freertos example.

Thanks,

Jorge

Hi Jorge,

You need to "Generate processor expert code" before compilation.

As far as I know we don't have any FreeRTOS example without SDK.
