RTOS/CC2640R2F: Global stack location and the view

Part Number: CC2640R2F

Tool/software: TI-RTOS

Hi,

Device	CC2640R2LAUNCHXL
SDK	simplelink_cc2640r2_sdk_1_50_00_58
IDE	IAR8.11.2
Reference Project	Multirole

We are checking the stack usage in the entire project. We have tested the independent task stack. But want to know about the global stack.

from the .icf file I have done the below calculations.

Global Stack Calculations

RAM_BASE = 0x20000000

RAM_SIZE = 0x00005000

FLASH_ROM_BUILD = 2

RESERVED_RAM_SIZE = 0x00000C00

BIM_SHARED_RAM_SIZE = 0x04

RAM_START = RAM_BASE

RAM_END = RAM_START + RAM_SIZE - RESERVED_RAM_SIZE - BIM_SHARED_RAM_SIZE -1

0x20005BFB = 0x20000000 + 0x00005000 - 0x00000C00 - 0x04 -1

STACK_SIZE = 0x400

STACK_START = RAM_END

STACK_START = 0x20005BFB

STACK_END = STACK_START - STACK_SIZE -1

0x20005FFA

But the above mentioned Stack details/address is not visible in memory view . How can I view this global stack?

Thanks

Hi Niranjan,

Have you tried enter the address of the RAM region directly into memory view?

Hi Edvard,

Thanks for reply.

Yes I have tried in memory view. But I just see there only "dashes" like in the image.

It seems like you calculations of the RAM_END address is off. Note that the RAM_SIZE is 0x5000, so any address above 0x20005000 is not a valid address within RAM, such as 0x20005BFB...

I get the following address for STACK_START = RAM_END = 0x200043FB. Try that address in the memory view.
