RTOS/TMS320F28069: RTOS/TMS320F28069:

Tool/software: TI-RTOS

Hi,

I am using Sys Bios 6.45.1.29 and Code Composer Studio, Version: 7.0.0.00043 on TMS320F28069. 

I am using the following .cfg file.

I want to increase stack size and heap size. I have sufficient memory e.g. I use just 25% of RAM as shown in Memory Allocation. But if I increase stack size from 256 to 512, strangely the stack overflows.

What should I check. I will highly appreciate any directions, links etc. 

Thanks 

Jawwad
