Hi everyone,

I would like to have more than one firmware 
on LPC2103 (each firmware in one sector).

Is it possible to do such thing?
How to execute ie. firmware in 3rd sector?

Is there some example?

Thanks,

Srdan Suka

Sure.

You will have to write a boot-manager read e.g. an I/O pin and than jump 
to the second or 3rd sector.

Is there some example of such "boot-manager"?

Thanks,

Not that I know of.

main()
{
	if ( testIO() ){
		asm(" bl 0x2000");
	} else {
		asm(" bl 0x4000");
	}
}

Just add the correct startup code and write testIO.

Thanks, it would be enough to start :)
