'[PIC] dsPIC Bootloader download available'

Hi all,
Daniel Chia has written a dsPIC bootloader for the
30F4011 for his micromouse project. He is kind enough
to allow me to distribute the code to the public.
It is still based on Tiny Bootloader for 18F.

Please go to Microchip Forum to download the zip
archive of the asm source and the VB project.
http://forum.microchip.com/tm.asp?m=105293

By the way, if anybody can provide a better
website to post, let me know. Thanks.

Regards,
Xiaofan

Daniel Chia has allowed me to distribute the code to the
public. It is provided as is. The code is only for dsPIC30F4011
now and it is running at 32MIPS (a bit over the 30MIPS limit).
The VB source code needs some work as well. It would be
great appreciated if you post back the changes but it is not
strictly necessary.

The VB hex file parser is from Microchip.

The bootloader is still similar to Tiny Bootloader so we need to thank
the author of Tiny Bootloader here as well. Thanks for proving so much
useful information on the web page, Claudiu!

Somehow, zip file is no longer supported in the upload.
Please change the extension from txt to zip.

Take note that the assembly code is using old syntax.
It is better to use code attached now.

Originally I want to port this to 30F2010 but I need
some time to learn dsPIC assembly and I know almost
nothing of VB. Therefore I think it is much better
to release it to public and hopefully better code will
come out from this. There are some limitation of the
bootloader. The VB interface need to be changed a bit
as well. Moreover I will prefer a GCC command line version
across Windows and Linux.

Hopefully the information will be useful to those who are
interested in dsPICs. It would be greatly appreciated that
enhancement to the code is also made available to the public.

Regards,
Xiaofan

Sergey A. Dryga is so kind to provide the hosting for Daniel Chia's
dsPIC bootloader.

The URL for the link is as following.
