CCS/TMS320F28377D: How to understand data un Stack Usage View?

Hello Everyone,

I am working with CCS version 10, and in the Stakc Usage view I am trying to see the amount of stack memmory used by each of the functions in my firmware.

I have defined my stack size as 2048 Bytes:

but in the view, the total amount seems to be 862 Bytes, as shown in the picture below. Why is that?

Many thanks in advance,

Andreu

The link below should help explain this discrepancy:

Hello ki,

Many thanks for your quick answer.

I have another question about this issue. In the web page http://software-dl.ti.com/ccs/esd/documents/ccs_stack_usage_view.html it states that:

"The color shading indicates whether you are close to the limit of available stack space (shown as yellow) or not (shown as green). To avoid hitting the limit, you could free up some stack usage or increase the system stack size."

In my case I can see:

If the size of my stack is 2048 bytes, why is the bar yellow when the amount used by a function is 862 bytes (less than 50 %)?

Many thanks,

Andreu

Can you show me a screenshot of the entire stack view? I want to see the names of the functions, etc
