Has anyone been able to get printf to work in a C++ application?

[dave408]

I'm still working on getting KDS 2.0 to work with KSDK 1.1 with a C++ application.  I have started with the simplest of applications, which is basically what comes out of the new KDS Project wizard, the addition of all necessary include folders, the linker libraries, and a printf statement.  Whether I try printf or putchar, nothing goes to the serial port.  Instead, the program seems to reset over and over again.  In the screenshot below, if I hit F6 to single step over the printf, it ends up back at main.

If I don't use the printf and stick with the default behavior from the wizard (increment a counter), it works fine.

Has anyone had luck with this?  I've included my project here.  If anyone is willing to take a look at it and see if there's anything wrong, I would appreciate it!  You can import it by using File -> Import -> Project of projects.  Thanks!

Hi Dave,

Please send your project , or it can't open your project.

And if you want to use printf() on KDS-KSDK, you can add the "fsl_debug_console" component .

Have a great day,
Alice

Hi Alice, thanks for your reply.  I've shelved this project temporarily as it seemed to be related to the C++ project I was trying to use.  I gave up on C++ and am going to write my application in C instead.  If I run into printf problems again, I'll post a new question with a project that will hopefully open properly!
