FreeRTOS support Cortex-R52

Kernel
1

Hi team,

I would like to using FreeRTOS for Cortex-R52.
Do we have any port that support this processor?

Regards

The RTOS ports for the ARMv7-R and ARMv7-A are very similar. Would that also be the case for a ARMv8-R port, but not an ARMv8-A port? We have support for 64-bit ARMv8-A in the download, but not the R equivalent. Which chip are you using?

I’m working with S32S247 chip. Per my understanding, this processor support for AARCH32 Execution state and Arm/Thumb-2 instruction set. Can we have a portable code for both Arm and Thumb instruction set for this processor because i’m not familiar with Armv8-R?

The S32S247 with its SMP and safety features does not have a port to FreeRTOS. It may be possible to use the ARMv8-A to get a single core version of FreeRTOS running.

Shall I know where I can get ARMv8-A port reference code? I only see ARMv8-M port code in source tree.
Thanks!

Hi,
I am also planning to use FreeRTOS for Cortex-R52. Are there any demo applications available for reference? I am new to RTOS and I need to run my C++ application in FreeRTOS environment.

Depending on which Cortex-R52 part you are using, there may be some demos available from your vendor. If not, you can start with a bare metal project and get it running. Then add FreeRTOS and we can try to help if you face any issue there.

Hi,
We are also trying to port FreeRTOS to Cortex-R52 with SMP and MPU enabled.

Could you recommend any partners who would be able to support us?

Don’t know any partners have done this.
But if you’d like to start a bare metal project, here is a good checklist for SMP porting:

Hi FreeRtos Team,
Is there any reference Freertos port code to CR4 starup-cr4.s file with details of all interupts related to scheduling and systick interupt handlers?

Thanks @sitikela for opening a separate thread for your request. Lets continue the conversation there.
