AWR2944: SBL for freertos

Shine

Part Number: AWR2944

Hello Champs,

The SBL demo in AWR2944 mmwave_mcuplus_sdk_04_04_01_02 is nortos. Customer need the SBL on freertos. He tried to replace the nortos lib with freertos.awr294x.r5f.ti-arm-clang.release.lib, but the sbl can't load APP. Is there something missed? Does SBL support freeos?

Thanks
Regards

Hello Shine,

Yes, it is possible to port it to freertos, but just replacing the library doesn't work.
The customer can compare another project like hello world which has a freertos and nortos example.
They will understand better and also realize you will have to create tasks and schedule the same.
I don't see any benefit of porting the same to freertos as well as it adds extra complexity.

Hello Saswat ！

I've compare the project hello world,and I create the Task in SBL,but when run vTaskStartScheduler, the system is abort,and stay in the “HwiP_prefetch_abort_handler“” interrupt.

The base project is sbl_qspi，I replace the nortos lib with freertos.awr294x.r5f.ti-arm-clang.release.lib, add the HEADERS to the project，and modify the __SVC_STACK_SIZE to 4096.Then create one Task for test. It run failed,and when call function ”vTaskStartScheduler“，it abort and stay in “HwiP_prefetch_abort_handler“

Hello yang,

Instead of creating a new project, can you first modify the hello world, with the current code and then see if its working on your end or not.

Hi Saswat！

In othor block,It seems not support the Freeos for SBL, Are you sure the 2944 can support it?

Hello Yang,

It is possible, but TI does not support it officially in the SDK. As it is a single task, there is no requirement for anybody to use a FreeRTOS. You can implement it if you want, but as I had mentioned, there is no benefit in porting it.

You can go ahead and implement it if needed.
