Below sprintf works in LPCexpresso project for LPC1343, but gets below compile error in LPC1345 project.
I assume it related to the differing libs each processor uses.
(I'm using LPCXpresso v4.2.0, but just tried v5.0.12 and it fails too)
Is there a fix for this?

#include <stdio.h>

sprintf((char *)(test)," %d \r\n", len);

compile error:

Hi,

You are not linking against the right C library. for sprintf you'll need atleast the nohost variant(and for semihosting the semihost variant). See:
http://support.code-red-tech.com/CodeRedWiki/LibraryVariants
and
http://support.code-red-tech.com/CodeRedWiki/SwitchingCLibrary

Regards,
Wouter

Thanks for quick response and info I needed.

Change of MCU Linker from Redlib(none) to Redlib(semihost)
allowed clean compile using sprintf.
