printf() does not work unless library is changed

[m_hamza96]

Hi,

I'm having a problem in my project where printf() does not print anything to console when MCUXpresso is started. It will work if I go into quickstart panel->change library/header type and select a different library, build the project, then switch back to newlibnano and build again. However, this has to be repeated every time MCUXpresso is restarted.

MCUXpresso version: v11.3.1

Micro: LPC1549

Thanks

Hello m_hamza96,

Some of the libs do not support Printf(), about detail please refer to 16. C/C++ Library Support of MCUXpresso IDE User Guide, I attached it for you.
