| ORG errors with bootloader |
 Posted: Fri Dec 16, 2005 2:27 pm |

I'm having some odd problems since updating my compiler. I am using a bootload based on the example code which came with the compiler. My target is a PIC18F6720.
The following code use to work fine in my main application. Now it causes an "Invalid ORG Range" error. I've tried changing a number of things but to no avail.
Has anybody come across this before?
| Code: |
#define LOADER_END 0xfFF
#define LOADER_SIZE 0xdff
#ifndef _bootloader
#define VERSION_HIGH ((FIRMWARE_VERSION)>>8)
#define VERSION_LOW ((FIRMWARE_VERSION)&0xff)
#if defined(__PCM__)
#build(reset=LOADER_END+1, interrupt=LOADER_END+5)
#elif defined(__PCH__)
#build(reset=LOADER_END+2, interrupt=LOADER_END+8)
#endif
#org 0, LOADER_END {}
#endif

1. Were you using a different PIC for the code that worked ?
If so, what PIC were you using ?
2. Did you change compiler versions ? What was your old version
and what is your current version ? |

1) we've always been using the same PIC 18F6720
2) It use to work fine on previous compiler versions 3.191, 3.202, 3.204, but does not now work on our current version 3.241. |

If I take your code and drop it into a test program, it compiles with
no errors with PCH vs. 3.241.
| Code: | #include <18F6720.H>
#fuses XT,NOWDT,PUT,BROWNOUT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
#define LOADER_END 0xfFF
#define LOADER_SIZE 0xdff
#ifndef _bootloader
#define VERSION_HIGH ((FIRMWARE_VERSION)>>8)
#define VERSION_LOW ((FIRMWARE_VERSION)&0xff)
#if defined(__PCM__)
#build(reset=LOADER_END+1, interrupt=LOADER_END+5)
#elif defined(__PCH__)
#build(reset=LOADER_END+2, interrupt=LOADER_END+8)
#endif
#org 0, LOADER_END {}
#endif
//=============================================
void main(void)
{
while(1);

If you try the following code it causes the problem. It appears to be related to using interupts. Remove the interrupt and it compiles properly using PCH ver 3.241
| Code: | #include <18F6720.H>
#fuses XT,NOWDT,PUT,BROWNOUT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
#define LOADER_END 0xfFF
#define LOADER_SIZE 0xdff
#ifndef _bootloader
#define VERSION_HIGH ((FIRMWARE_VERSION)>>8)
#define VERSION_LOW ((FIRMWARE_VERSION)&0xff)
#if defined(__PCM__)
#build(reset=LOADER_END+1, interrupt=LOADER_END+5)
#elif defined(__PCH__)
#build(reset=LOADER_END+2, interrupt=LOADER_END+8)
#endif
#org 0, LOADER_END {}
#endif
int i;
#INT_RTCC
void rtc_code() {
i++;
}
//=============================================
void main(void)
{
while(1);

To get it to compile with PCH vs. 3.241, I had to increase the value
shown in bold below to 9. I'm not sure how this will affect your
program. You'll have to look at the .LST file.
