Stack Consumption for HC12 using Code Warrior v5.2

MerlinBDX — Wed, 04 Feb 2026 17:25:24 GMT

Hello,

I am trying to compute the stack consumption on a MC9S12XDP512 microcontroller.

According to Code Warrior's v5.2 Build_Tools_Utilities.pdf in the Stack Consumption Computation section: "Older versions of the compiler may not issue the information. Also, this feature is currently only supported for HC(S)08 derivatives."

I want to know how to compute the stack consumption for my application. I saw in answer to another question that CW v5.1 did support the feature, therefore v5.2 should as well, I presume.

Thanks in advance.

I have activated the options you mentioned and when compiling I get this message:

Following the PDF of the Build Utilities, I went into the PRM file and added these lines at the end:

But now I am getting this error:

On this line:

Can you please advice on how to solve this?
