Starting program at 0x04

RodP · Guest

Hello,

I'm trying to use Bloader from Sparkfun to load CCS C generated code. The readme file says the program must start at memory location 0x0004 and the interrupt vector will still operate properly from the same location. How can I change the program to do this? The only thing I could find on this was to use: #build (reset = 0x1, interrupt = 0x05)
#org 0x0f00,0x0fff{}

I'm throughly confused by this and would appreciate any suggestions!

What PIC are you using it for ?

If it's the 16F877 or a related PIC, then use the bootloader from
http://www.microchipc.com/PIC16bootload/

It doesn't have any restrictions on putting code at adresses 0 to 3.
They also tell you how to use it with CCS:

It's strange that Sparkfun wrote their bootloader in CCS,
but don't offer instructions on how to use it with CCS.

Thanks to PCM Programmer. I was wanting to use this with a 16F88 and it appears that isn't an option. Maybe CCS will sell a reasonably priced bootloader for use with their compiler that's able to work with MPLAB as the ICD.
