Hi everybody.
I'm starting to use freeRTOS for the first time and trying to build a small program to blink leds with a pic18f4580. I've already created a project file following this webpage http://solar-blogg.blogspot.com/2009/06/setting-up-freertos-for-pic18-using.html, but everytime i get to the linking part i get the error:

Error - section '.udata___heap.o' can not fit the section. Section '.udata___heap.o' length=0x00000400

I also get some warning messages saying

FreeRTOS\Source\queue.c:1028:Warning [2058] call of function without prototype

and

FreeRTOS\Source\list.c:66:Warning [2066] type qualifier mismatch in assignment

Can someone give me a few ints about these problems?
Can I also use tiny bootloader to run the code generated?

Regards

Just don't do it, get yourself a real processor and a real compiler.
