dsPIC30F3013 freeze problem

[gozi]

Hi,
I have the following problem:
This code not working on dsPIC30F3013. After reset the dsPIC not respond.
I use EasyDSPIC3 board, Mikropascal for dsPIC 5.0.0.0 and 30F3013 at 80Mhz. (This code work fine on 30F6014.)

Code: Select all

program test;
const os: array[10] of array[4] of word =  ((10, 10, 10, 10),
                                            (10, 20, 30, 40),
                                            (10, 20, 10, 20),
                                            (10, 20, 10, 30),
                                            (20, 30, 30, 10),
                                            (10, 20, 20, 30),
                                            (20, 10, 10, 20),
                                            (40, 20, 30, 20),
                                            (10, 30, 20, 10),
                                            (30, 10, 30, 10));


var i: word;
    v1,v2,v3,v4,v5,v6: array[96] of word;
begin
ADPCFG := $FFFF;
TRISB := 0;
for i:=0 to 94 do
v1[i]:=0;
for i:=0 to 94 do
v2[i]:=0;
for i:=0 to 94 do
v3[i]:=0;
for i:=0 to 94 do
v4[i]:=0;
for i:=0 to 94 do
v5[i]:=0;
for i:=0 to 94 do
v6[i]:=0;
 while TRUE do
    begin
      LATB := $0000;
      Delay_ms(1000);
      LATB := $FFFF;
      Delay_ms(1000);
    end;
end.

Thanks for advance.

Hi,

We tested your code and we got the same behavior.
The problem is that your globals are using a lot of RAM and the compiler is not reporting that (we will fix this). You should get "Not Enough RAM" message.

If you go to EditProject menu you can increase the RAM space reserved for the Static variables, move the slider to the left (your code works for 40-60). Of course this will reduce the RAM space reserved for the dynamic variables.

would it perhaps be possible to have the compiler report the memory-needs for both static and dynamic in some future version ? It is more or less blind adjusting right now.

Thanks for answer, Milan. That works.
