problem with FLASH_WriteDoubleWord

[jalal_am]

Hi all,
I am using FLASH_WriteDoubleWord in my program, but I cannot get it working. I read the help file, but unfortunately still in trouble. I would be grateful if somebody provides me with a simple example.

thank you for your help.

Hi,

Can you tell me which MCU are you using,
which address have you tried to use in FLASH_WriteDoubleWord?

Kind regards,
Lana

Thank you for your response.
I am using dsPIC33EP512MU810. I manage to use FLASH_Wrire, FLASH_Read, etc. but unfortunately I could not utilize FLASH_WriteDoubleWord and FLASH_ReadDoubleWord. I would be grateful if you send a simple example or give me a brief explanation.

Code: Select all

  FLASH_WriteDoubleword(0x055400, BUFF1A);

Thank you

I also have a problem with Flash_Erase

Code: Select all

main{
....
   
       FLASH_Read(0x055400, ReadWordArr, 64);
      for (LOP=0; LOP<4; LOP++){
       LATD=ReadWordArr[LOP];
       delay_ms(10000);
    }

while (1){
.....
for (LOP=0; LOP<4; LOP++){
    // LATD=BUFF1A[LOP];
    WriteWordArr[LOP]= BUFF1A[LOP];
    // delay_ms(5000);
    }
 for (LOP=4; LOP<64; LOP++){
    WriteWordArr[LOP]= 0;
    }
    FLASH_Erase(0x055400);   
    FLASH_Write(0x055400, WriteWordArr);
    FLASH_Read(0x055400, ReadWordArr, 64);
    for (LOP=0; LOP<4; LOP++){
    LATD=ReadWordArr[LOP];
    delay_ms(5000);
    }
....}}
    

as you see the FLASH_Erase in an infinite while loop. a funny thing happens, and it is that the FLASH_Erase reset the MCU second time it is executed, and never again happens! I mean that First I see all output erased ( output before while loop); then I see the correct values on output ( it means that erase, write and read are executed perfectly). but on next recursion, MCU reset and I see cleared output (0xFFFF). after that never this error occurs and every thing is fine. could you please share your comment on this issue, also?

Thank you for your help
