I am looking for a bootloader for a pic18f2685. I tried modding an existing one but no success. Are there loaders available on the net that I can use ? The most common used ones do not support my chip.

My bootloader supports your device. Please take a look at the homepage.

I suggest you to take a look at TinyBootloader - http://www.etc.ugal.ro/cchiculita/software/picbootloader.htm
It is written in assembler and it can easily be modified for almost any PIC16F and PIC18F.

cheers

Oops, the correct address is http://mrmackey.no-ip.org/elektronik/ds30loader/

Compared to TinyBootloader:
* open source gui
* supports PIC16, PIC18, PIC24, and dsPIC
* command line interface
* ready to use mplab project
* single mplab project for each family
* works in Windows, Linux, and MAC

hmm, doesnt look bad.
What size does the bootloader occupy on the PIC?

For PIC18 I offer 2 versions, the regular with write verification is 160 words.
The smaller to compete with Tiny is 100 words. Do you REALLY need those
120 extra bytes?

The details are found in the datasheet and firmware manual. They are found
to the right on the homepage.
