Bootloader

[mister_e]

There's a few different bootloaders here and there (such as TinyBootloader), the one i use is made by Mecanique and come with the full version of MicroCode Studio, the schematic you need to use is like bellow...


In your PBP code, you just need to add

DEFINE LOADER_USED 1

in Microcode studio, you choose MicroCode Loader as programmer.

Hi Dear Mister_e
Thanks for your reply. Unfortunately I haven't MicroCode studio plus and MicroCode loader :-(
I found Tiny Bootloader- As you mentioned- and downloaded it from here:
http://www.etc.ugal.ro/cchiculita/so...bootloader.htm
Have you worked with tiny bootloader? I think that I should write my program with microCode studio ( with--> DEFINE LOADER_USED 1 ) after commpiling send .HEX via Tiny Bootloader. Is it true? Does it work?
Thaks again.

Yup make sense to me. now if TinyBootloader utility have it's command line, that would be great 'cause you could launch it directly from Microcode studio as a third party programmer.

Out of curiosity, which PIC are you going to use? Which OSC speed?

Dear Mister_e
Thanks for your reply. I want to use PIC16F877 and 10 MHz Osc. (Is it possible to use PIC16F628?)

not suppose to work with a 16F628 as it don't have the capability to write/modify it's own codespace. 16F88 will work.

hi
mister_e, maybe you remember my problem in the next topic
http://www.picbasic.co.uk/forum/showthread.php?t=7627

i am fix my problem usign tinybootloader also, but i have only a waring message,
when i am load my program usign the tiny, the software say :

WARNING: PCLATH not initialised before GOTO! ... sucessfully repaired

and the load continue, and work fine, i am put only DEFINE LOADER_USED 1

that place i need put this GOTO command for skip this warning??????

thanks for all

Regards

I already heard it, but seems it's more a PC utility problem and it's just an annoying warning without any effect to your PIC code.

Yup the only thing you have to do is place a DEFINE LOADER_USED 1 and you're in business.

Don't worry about the warning, just ignore it.
