EZ430-RF256x SDK stack/heap configuration

Ibon Zalbide

Other Parts Discussed in Thread: MSP430BT5190

Hi,

I am developing an application to send data through Bluetooth SPP to a PC. I am using a PCB including an MSP430BT5190 + PAN1325, and the EZ430-RF256x SDK. The basic application is working fine.

However, when I define new variables I am having troubles with the stack size. I can not use as many variables as I need, as at one point the programs crashes (I have added about 100 bytes of variables). Debugging the application, I receive a warning about the stack being outside its boundaries. I have tried to increase the stack/heap size in the project configuration, but the problem persists.

I know there is some additional heap configuration in the RTOS configuration, but I do not know what I need to change to allow more variables in my application.

Any help?

Thanks,

Ibon

Changing the stack and heap size as part of the project configuration will have an impact only before the call to the FreeRTOS scheduler is invoked as part of main.c.

The developer's guide has information on modifying the configuration under the heading "Modifying configTOTAL_HEAP_SIZE".

I found that section in the developers guide really helpful. Thanks for that.
