Hello everyone ! I’m currently porting some code from a TI RM42L432 to a TI RM46L852. And by the way I want to update the freeRTOS kernel. I downloaded the last version of FreeRTOS and I’m currently trying to understand why I’m facing some implicit declaration. Here is my problem, I use the file m…

There was a related post recently which might be helpful and also this documentation FreeRTOS-MPU - ARM Cortex-M3 and ARM Cortex-M4 Memory Protection Unit support... FreeRTOS is a portable, open source, mini Real Time kernel. A free RTOS for small embedded systems …

Thank you for your quick repsonse. I’ve seen this post but in my case I think I use MPU because it was set in my last project. I’ll check the documentation. Best regards,

[image] babylone: RM46L852 According to the data sheet ( https://www.ti.com/lit/ds/spns185c/spns185c.pdf?ts=1637240525944&ref_url=https%253A%252F%252Fwww.google.de%252F ), your POD appears to have an MPU.

Yes It have i’ve already check the datasheet but I don’t know why I can’t configure FreeRTOS to use it. I think I misunderstand something here on how to configure correctly freeRTOS because this is the first time I do such things. Best regards RAc

[image] babylone: In my last project I had this declaration in the portmacro.h header file but now I don’t have it in my new portmacro.h which I got from FreeRTOS/Source/portable/CCS/ARM_Cortex-R4/portmacro.h. Where did you get the original portmacro.h header file from? I would think that the…

[image] babylone: I got from FreeRTOS/Source/portable/CCS/ARM_Cortex-R4/portmacro.h This port does not have MPU support. Where did you get the original port from? Thanks.

Hello aggarg, I don’t know exactly where the last port com from… I think it comes from the halcogen freertos code generator. I’ll try to build a project with halcogen for the RML46L850 which is very similar to the 852 and see what are the differences. But I don’t want to go through halcogen to impo…

[image] babylone: But I don’t want to go through halcogen to import FreeRTOS because it seems to don’t be at the latest version and in the future I want to be able to import and update freeRTOS easily. Understood. I am just trying to understand how you got the MPU port if it is not officially…

Hello aggarg, I created a project with halcogen for the RM46l852 with FreeRTOS and it gave me the mpu port. Now i’m facing new issues but I don’t know if it is related to FreeRTOS or CodeComposerStudio (creating output section xxx without SECTIONS specification). Regards,

I think that port is written and supported by TI. If you can elaborate other issues you are facing, I can try to help. Thanks.
