Debugging an array of pointers to structures

michaelhuslig — Fri, 18 Aug 2017 05:58:34 GMT

I have an array of structure points which is working in my code (struct userst * user_ptr[MAXUSERS]). What I want to do in debug is hover over the declaration to see what is there. What I am getting now is just:

Expression Type Value

user_ptr struct userst *[] [0]

Using the memory browser I can see I have entries, and my code sees them properly too. It would be nice to see the pointers in debug, even better to see the structures.

This is KDS3.2 with the latest updates using a MK22FX512

Hello ,

Could you please show your project to let's see your code in detail .

Then I can debug it on my side to check .

Alice,

I forgot to mention that I am using PE micro's Multilink Universal. Is

this something to do with the gdb server? How much of my project would

you need. Wouldn't you need my custom board in order to see what I am

seeing?

Hi Michael,

I just want to know detail what information you want to see.

Usually we check variable on ''Expressions " view of KDS you also mentioned :

If you want to check variable when the program on board is running, you can refer to this thread :

Automatic Variable, Expression and Memory Display with GDB and Eclipse | MCU on Eclipse

Hope it helps

Have a great day,
TIC

Hi Michael,

which debug probe you are using should not be relevant.

I tried to reproduce your problem, but works for me:

I used the following:

#define MAXUSERS 3
typedef struct userst {
  int a;
} userst;
struct userst a, b, c;
struct userst* user_ptr[MAXUSERS];
‍‍‍‍‍‍

What is really needed is a piece of code to reproduce what you see.

I hope this helps,

Erich

Erich,

My structures were a lot more complicated. I ended up declaring

individual array pointers and assigning them the same values in the

array. This way I was able to examine the selected structures I needed

in debug.
