EP4 and icd

[piort]

hi ,

i just receve my EP4 today and start to play with the ICD... Play is the good word ))) BTW im front of a nice bug...
make a test prog...
build and program in ICD...
start debug windows...
clic on 'add all' button...
start the session...
play a bit with the step over...
scroll down to see bottom variable...
and crash... trying that 10 time with the same result
no time to reach the 3/4 on the var... acces violation raising
need to 'ctrl-alt-del' to close MP

last MP version and picflash 7.04

hope that will hlp to point the prob


happy coding

It would be great to give us the code you tried to debug so we can catch the error too.

hi,
there my testing code...

Code: Select all

program test_pascal;

var in_text : string[7] ;
var out_text : string[7];
var k: byte;


procedure init;
begin
ADCON0.0 := 0;
ADCON1 := $FF ;
CMCON  := 7  ;

TRISC := 1  ;
Trisb := 1 ;
portc := 0;
portb := 0;

LCD_init(portd);
delay_us(200);
lcd_cmd(lcd_clear);
lcd_cmd(lcd_cursor_off);

lcd_out(1,1,'Entrees: ');
lcd_out(2,1,'Sorties: ');

end;

begin
 init ;
 while true do
 begin
 for k := 0 to 7 do
       if testbit(portb,k) then

       in_text[k] := '1' else in_text[k] := '0' ;
       LCD_out(1,9,in_text) ;

  for k := 0 to 7 do
       if testbit(portc,k) then
       out_text[k] := '1' else out_text[k] := '0' ;
       LCD_out(2,9,out_text);

 end;
end.

I have try it again just before posting to be sure and that do it again...
Access violation with few memory address...

HW: EP4, 16f877a,8mhz...

happy coding

It seems it is not the problem with ICD at all, it is connected to watch window, which fails to show a variable. If you try it out in simulator you will see the same error.

Anyway, we will fix this. Thanks for discovering the issue.
