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

Try support@... ?!

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.

If you implement calls that use stdin/stdout in debug, and you have linker
option set, all stdin/stdout happens in terminal I/O window.

If you implement putchar and or getchar you effectively change your
stdin/stdout endpoints.  So for debug and or release you might want to use
the serial port for stdout, just implement putchar to send character to your
desired serial port.  You can make stdout your I2C port if you like.

You get no Terminal I/O in C-Spy regardless of linker setting if you
implement putchar/getchar.  So perhaps conditionally compile putchar and or
getchar based on your needs.

Using the Terminal I/O consumes one hardware breakpoint.  If you're not
using Terminal I/O disable the linker setting.


int putchar(int c);		// implementation only needed for printf()
int getchar(void);
