Tool/software: Code Composer Studio

In my application there is array size of 2048 byte. Firmware is work.

After change size on 4096, firmware aborted (goes to the vector _dabort).

Why it happand?

Hi Nikita,

Please increase the stack size. The default stack size is 0x800 if you use TI code composer studio.

I set stack size 0x1000 and 0x1200 - doesn't work.

Perhaps should set some additional options (change STACKS length in sys_link.cmd)?

How to change the stack size:

1. Change the stack size in CCS linker setting (you have done this already): --stack_size=0x1200

2. Change the stack size assigned to user mode in sys_core.asm: userSp .word 0x08000000+0x00001200

3. Change the memory size used for stack in linker cmd file: STACKS (RW) : origin=0x08000000 length=0x00001700
