[lastengineer31]

Hi , i need help , i m working with pic18f4550 using FreeRTOS, i ve create an USB task but i had this error :


MPLINK 4.34, Linker
Copyright (c) 2009 Microchip Technology Inc.
Error - section '.udata_heap_1.o' can not fit the section. Section '.udata_heap_1.o' length=0x000001f8
Errors : 1

i think this error is because of memory of the pic18f4550
can any one tell me what to do
thank u

I think the memory that u use must not exceed the maximum memory that is already defined in the library. u can refer the compiler's user guide.

decrease the number of global and static variables... if any constants the declare it properly... use unsigned declaration to variable if you have used signed int or char....

if any big size array is defined then use it properly...
Solution for Error - section '.udata_main.o' can not fit the section

Well we need to see your code before we can help you.

Does the project with your simple task compile properly?

I suggest zipping up your project and uploading it or if it is fairly short post it in code tags.
