I believe that this may be caused by including CSPY options.  Things
like printf work in debug to display messages to the debugger screen.
The underlying support routines for printf eventually resolve to
__write.  When you compile for release, obviously there is no debugger -
so these go unresolved.  Try turning off CSPY option in debug - I bet
you get the same error.  Track down the printf's and related and the
getc's .  You might want to conditionally compile them in based on a
#define used only in debug environment.

Subject: [lpc2000] [IAR EW-ARM] Internal Error???

 



When compiling the project in debug mode, there is no
error that EW-ARM gives. But compiling in release
mode, the following errors occur and .hex file can not
be generated?

Any suggestion??



Error[e46]: Undefined external "__read" referred in
?getchar ( C:\Program Files\IAR Systems\Embedded
Workbench 4.0\ARM\LIB\dl4tptinl8n.r79 )

Error[e46]: Undefined external "__write" referred in
?putchar ( C:\Program Files\IAR Systems\Embedded
Workbench 4.0\ARM\LIB\dl4tptinl8n.r79 )

Warning[w52]: More than one definition for the byte at
address 0 in common segment INTVEC. It is defined in
module "?RESET" as well as in module "?RESET"

Internal Error: In function: unknown
Diagnostic: unexpected exception
P0: 1    P1: 0
