| write program memory PIC18F67K90 |

I've written a small program to test the Write_Program_Memory command but when I compile it (PCH V4.116) no code is generated for the command. Has anybody else had this problem, and if so how was it resolved ?
Here is the program
| Code: |
#include <c:\program files\picc-h\devices\18F67k90.h>
#fuses HSM,PLLEN,WDT2048,BBSIZ1K
#use delay(clock=32000000)
#use rs232(baud=9600, xmit=PIN_D4, rcv=PIN_D3)
byte data_buffer[128];
void main(void) {
write_program_memory(0xa00,data_buffer,128);
} |

I agree, it's not there. It just returns. I compiled your program with
vs. 4.119 and it is there in that version. Do you have the possibility of
upgrading ? |

Hi, I have the same exact problem here with a PIC 18F2480, but with compiler version 4.120... this is the lst output:
| Code: |
.................... write_program_memory(addr, data, count);
3D20: MOVFF 4E,FF8
3D24: MOVFF 4D,FF7
3D28: MOVFF 4C,FF6
3D2C: CLRF FEA
3D2E: MOVLW 57
3D30: MOVWF FE9
3D32: MOVFF 56,77
3D36: RCALL 3A2E
|
but there is no code at memory location 3A2E... |

It probably really is there, it's just that the compiler is not showing it to you.
To make it show you the code, edit the 18F2480.h file and comment out
the #nolist statement at the top of the file. Example:
| Quote: |
//////// Standard Header file for the PIC18F2480 device ////////////////
#device PIC18F2480
//#nolist
|
Then re-compile and look for the code in the .LST file. |

| Thank you, now I see it... So I guess my problem is different. The PIC resets at that exact function (I tried placing a putc before and after). Do you have any hints? (do I have to open a new topic?) |

Start a new topic and post a very small and compilable test program.
It has to be a complete program with #include, #fuses, #use delay, etc.
But less that 20 lines, if you can show the problem with that few lines. |
