Hi,

I can not find my mistake. I want to clear the Int. flash & it does not work.

May somebody have a look in my code?

The code is executed from RAM, it's ok.

Thanks a lot.

Gabi

mkC ST10F269

It Works.

Thanks Neila,

ROMEN = 1

ROMS = 0

R8&9 - (0/0; 0/4; 0/6; 1/0; 2/0...)

It works for the Bank 0 R8&R9 = 0. (deletes my software :))

My controler goes through reset if I call the function below, on this point:

MOV [R5],R7

:(

Is something wrong configured?

Thanks a lot,

Gabi.

PFlash_RP PROC NEAR

MOV R1, #2H ; The second page

MOV R5, #02A54H ; For the 1st & 3rd write

MOV R6, #015A8H ; For the 2nd write

MOV R2, #0A8H ;

MOV R3, #54H ;

MOV R7, #90H ;

EXTS R1, #4

MOV [R5],R2 ; 1st command

MOV [R6],R3 ; 2nd command

MOV [R5],R7 ; 3rd command

MOV R4,[R1] ; 4th command

RET

PFlash_RP ENDP

Hi Neila,

Thank you for your help.

The WDTCON register I did not read. The following hardware traps are analysed in my software & no one comes:

void NMI_trap (void) interrupt 0x02{...trap_cause = TFR;...}

void STKOF_trap (void) interrupt 0x04{...trap_cause = TFR;...}

void STKUF_trap (void) interrupt 0x06{...trap_cause = TFR;...}

void Class_B_trap (void) interrupt 0x0A{...trap_cause = TFR;...}

But I'll check all this points once more & I'll be back soon.

Thanks a lot.

Gaby.

So I'm back, I did some tests......

it was the watchdog, after the RP function and it restarts I read 0x06. But it can not be because I service the WD. I disabled the WD

DISWDT

EINIT

and now it hangs-up. :(

I did a small change in the RP procedure and it never returns:

EXTS R1, #3

MOV [R5],R2 ; 1st command

MOV [R6],R3 ; 2nd command

MOV [R5],R7 ; 3rd command

RET

MOV R4,[R1] ; 4th command

The generated code from RP function is:

:10300000E021E6F5542AE6F6A815E6F2A800E6F374

:103010005400E6F79000DC21B825B836B875CB002F

:04302000A841CB00F8

After the instruction B875 it hangs-up.

Thanks,

Gaby.

P.S. I copy this code on address 0xC000 (or 0xE000), it's free.

int (*PFlash_RPP)(void);

.....

PFlash_RPP = (void *)0xC000;

xmemcpy((ubyte huge *)PFlash_RPP, (ubyte huge *)PFlash_RP, 80);

.....

tst = PFlash_RPP();

Hi Neila,

I send the sources on your e-mail (neila_kraiem@yahoo.fr). The rest you can see from the code.

Thanks,

Gaby.
