| EX_USB_BOOTLOADER.C |

Hi,
I've just compiled the EX_USB_BOOTLOADER.C, but it shows message Error 71 "usb bootloader.c" Line 339(1,2): Out of ROM, A segment or the program is too large load_program. Hope someone can explain to me. What should I do ?

1. What's your compiler version ?
2. Did you un-comment the line for 18F4550 in ex_usb_common.h
as shown below in bold ? (and make sure all other PICs are commented out).

1) compiler Version 5.008
2)Yes, I did un-comment the line for 18F4550 in ex_usb_common.h |

I installed vs. 5.008 and was able to get it compile by editing the
usb_bootloader.h file in the Drivers sub-directory. I changed
the loader size as shown in bold below.
| Quote: |
#define LOADER_START (0)
#define LOADER_SIZE (0x1900) // Was 0x1800 |
I don't guarantee this works. I didn't test the code. I just got it to compile. |

I've change it to 0x1900 but it still give the same error.

I'm running vs. 5.008 with your posted program.
I don't know, try a larger size. Try 0x1F00. See what happens. |

I've tried...but the result still the same.
However when I skip the #int_default , it can be compile.
what does #int_default means?
| Code: |
//#int_default
void isr(void)
{
jump_to_isr(APPLICATION_ISR);
}

Oh, that's one thing I forgot. Ttelmah explained in this thread
http://www.ccsinfo.com/forum/viewtopic.php?t=55739&start=35
that it really should be #int_global. I edited your program and
changed it to this:
| Quote: |
#int_global
void isr(void)
{
jump_to_isr(APPLICATION_ISR);
}
|
Try that and see if it works. |

I don't know the reason. I'm compiling with vs. 5.008. I made only
the changes that I mentioned. It compiles OK for me:

Dear PCM,
Could you paste your EX_USB_BOOTLOADER.C and USB_BOOTLOADER.H code here. Maybe I can check if there is any differences. |

We're not supposed to do that, according to the forum rules which are in
the first thread at the top of the forum. I don't want to break the rules. |

| I really hope someone can confirm that the EX_USB_BOOTLOADER.C and USB_BOOTLOADER.H that i have is same with the latest version. Hope it can work. |
