I want to put a function in an specific address of memory like PIC C Compiler (#org).
I'm using MPLAB X, HI-TECH compiler and PIC18F4550.
In PIC C compiler:
#org 0x1000, 0x2000
void MyFunction()
{
}
//In other part of code I'll use: asm("goto 0x1000");
How to do this in MPLAB X with the HI-TECH compiler?
IIRC, you can set a function to an absolute address by using the "@" qualifier:
void MyFunction() @ 0x2A0
{
...
}
So the function MyFunction will be placed at address 0x2A0 in Program Memory.
int address = 0x20; **asm("goto "___mktstr(addr));** but If I use asm("goto "___mktstr(0x20)); works. I want to use goto to go a specific address using addr variable, perhaps there is another option like goto_address(addr) in pic CCS compiler. Thank you.

___mktstr(0x20) will return the string "0x20", but ___mktstr(addr) will return the string "addr".

use the linker command file to set the address of .text portion of MyFunction
MyFunctionfrom assembly (maybe as_MyFunctiondepending on compiler). \$\endgroup\$ – Majenko Oct 29 '14 at 14:29
