PIC18F4685 Bootloader

Hi Folks,

Can anyone recommend a bootloader for the 18F4685?

I've been using the 18F4620 for the last few months with the Tiny Bootloader, but this doesn't support the larger chip.

Cheers

Try to use CodeLoader from http://www.thebytefactory.com/ modifying source code. Set Max_Loadable to 0x16800 (90KB).

Thanks for the suggestion, however the compiler doesn't like setting the address to 0x16800

I get a couple of "info 300" lines and then an invalid ORG range error.

Any suggestions

Thanks

James

I tried to set the MAX_LOADABLE to various values, but for anything above 0xFFFF (4 F's) it gives a ORG range error.

What is the valid ORG range ? Is it the entire program memory space or some portion of it ?

I think the codeloader stores the boot program in the lower end of the Program memory, because I did not see any interrupt address moving or any such stuff. Please correct me if I am wrong.

Thanks,
