Re: [lpc2000] Flash variables

2005-04-22 by Richard Duits

Anything you define as const is allocated in the flash (at least gcc 
does this, have no experience with other compilers yet). Because the arm 
has only one address space, all memory (flash and ram) is the same, 
except you cannot write to the flash directly. The only reason you may 
want to copy to ram is because ram is faster than flash is some cases.
