Hello again,

changing flash mode from qio to dio did the job 🙂

One last question: Now I’m trying to send a simple text over UART.
I added the “Peripheral Drivers (IoT)” in Properties -> Frameworks. Why can’t I use os_printf(“hello”)?
There is a define is osapi.h:

#define os_printf os_printf_plus

The error is: ‘os_printf_plus’ was not declared in this scope.

Do I have to add a library in Properties -> Makefile settings -> Library Directories ?

Regards
