PICDEM FS USB bootloader CCS

[tretec]

Hi everyone,

I'm trying to use the CCS USB example code on the Microchip PICDEM FS USB board. I need to relocate the USB interrupt service routine because the first parte of the memory is occupied by the bootloader.
Does anyone know how if it is possible?

thanks in advance

Lookup #build in the help file.

Also the bootloader example code shows how to use this.

Yeah, I've tried in this way but there is some code in CCS USB code that points at a determined position, so of I try to reserve some space fore the bootloader I get this message error:

Hi!

You can try this :

#build(reset=0x800, interrupt=0x808)
#org 0x000, 0x7ff { }

Thanks a lot!!!
It works fine!!
GREAT!!

But now I've got a new question:
I had done a way like this. My old code was

#build(reset=0x800)
#build(interrupt=0x808)
#org 0x0000,0x07ff {} //bootloader()

but it didn't work..

Does anyone know why?

Congratulations for the forum, it's very useful and congratulations and tnx to the users!!
