Hi,
I'm new to NXP micro controller. What I'm trying to do is to print a string "Hello World" to debugger console.
I tried to make a C project (semihosting) by new project wizard and the printf function worked properly.
But when I tried to make the same with LPCOpen project, then it failed to print to console.
I followed the steps here http://www.support.code-red-tech.com/CodeRedWiki/UsingPrintf
to link my project to C library contained semihosting and also go to Project Properties -> c/c++ builder -> tool setting -> MCU linker -> Manage linker script -> Redlib (semihosting) and set on for semihosting support in debugger setting of debug configuration.
I have no idea what do i miss to get printf to work in LPCOpen project.
Thank you,
Cuong Hoang.

You need to change the configuration of your LPCOpen board library project. For details, please see:

Hi,
Thanks, I got it worked also with printf and DEBUGOUT().
By the way, I'm now working in NXP, can I directly contact for LPCXpresso Support via Lync somehow.
