Hi Guys, can someone please explain how I jump to my .S assembler program from within a new C Project.

As you guys know when creating a new Xpresso C project the C program creates the LPC4357 startup code and then has an infinite
loop at the end.

How do I jump to my assembler program just before the infinite loop. I have no idea how to do it. I'm not a C coder, I'm an assembler coder.

My assembler program is called _start:

And thanks for your support guys, I really appreciate it.

Pete :)

extern void _start(void); // declare the function

_start(): // call the function
