Hello,
I'm a beginner. I want to porting freeRTOS to PIC18f8680. The Problem is that the tasks are not called.

What could the problem be?
Thanks for help.

Here my linker script:

LIBPATH .

FILES c018i.o
FILES clib.lib
FILES p18f8680.lib

CODEPAGE NAME=vectors START=0x0 END=0x29 PROTECTED
CODEPAGE NAME=page START=0x2A END=0xFFFF
CODEPAGE NAME=idlocs START=0x200000 END=0x200007 PROTECTED
CODEPAGE NAME=config START=0x300000 END=0x30000D PROTECTED
CODEPAGE NAME=devid START=0x3FFFFE END=0x3FFFFF PROTECTED
CODEPAGE NAME=eedata START=0xF00000 END=0xF003FF PROTECTED

ACCESSBANK NAME=accessram START=0x0 END=0x5F
DATABANK NAME=BIG_BLOCK START=0x60 END=0xCFF

SECTION NAME=CONFIG ROM=config

STACK SIZE=0x60 RAM=BIG_BLOCK

you can Check length of source file path, the length of file full name is must not be more than 32 characters.

You were right it were more than 32 characters, but i have still the same problem that the tasks are not called...?
Further ideas?

The include file path must be vailed, please check it!

hi everybody,

i would like to port FreeRTOS to pic18 too. But i don't have much background on RTOS. Is there any document that i can refer to?

Thanks.

If you are using WizC or MPLAB then there is a pic 18 port already. The issue being getting the linker script correct. I think WizC will be easier to use.

Other than that take a look at the "implementation" pages of the FreeRTOS.org web site. It gives a lot of information, albeit for an AVR not pic.

Regards.
