PIC18F4580 bootloader not working

[jmaudley]

Hi,

I'm trying to get the ccs EX_BOOTLOADER working.

1. I've loaded the bootloader into the PIC.
2. I've hooked up the serial input/output tool via RS232
3. I've successfully powered-up the PIC with bootload PIN active which results in message on screen saying 'waiting for download'.
4. I've downloaded a simple flashing LED program
5. Powered-up the board again.

Result - LED not flashing so didn't work

Fuses are matched in both files.

It's a CCS CAN bus dev board so the hardware is all ok.

Compiler version PCWH 5.017

Not sure what I'm doing wrong at the moment.

Any assistance would be appreciated.

Remember you need to build the program to be loadable. You can just build a program and load it.

Look at ex_bootload.c, which shows how a program that is to be loaded needs to be built.

Missed BOOTLOADER.H
