TMS570 abort on startup

Matteo,

What code is causing the data abort?

you're right, sorry:

the  sciDisplayText function is called on second line of my main:

sciInit();
   sciDisplayText("STARTING_TMS570HDK_CS_SKIMREG_TEST",sizeof("STARTING_TMS570HDK_CS_SKIMREG_TEST"));

As you can see there's a "Error: memory map prevented reading..". I don't understand why.

The function should simply write a message on the console at the program startup and I've previously used this code snippet on a lot of other project with no problems.

Note that I've retested a previous project which works flawless, so there are no problems with my HW.

Target connection (ccxml) and GEL files are the same for both projects (I've made no modification on the default).

What else can I test?

As you can see from this screenshot both variables (text and length) are correctly defined on the previous code step:

but became unknown immediatly after entering the function (see my third screenshot)

Another  strange thing is shown in this screenshot:

The two variables has addresses which are mapped as "NONE" in the memory map, so the error reported by the debugger ("prevented reading ") is correct. In the other project (the working one) these adress are, as expected, not used.

Why variables are set to a NONE address?

How to fix the right behaviour?

I've solved the problem. As you pointed out was releted with heap overflow. I'm discussing it here:

thank you
