Hi

 

I'm trying to use sprintf with MQX lite on a KL15 but with Debug option "Ewl_noio" (needed for work without multilink ) an error occurs :

ARM_GCC_Support/ewl/EWL_C/src/stdio/vsnprintf.c undefined reference to `__pformatter'

 

I see here

Tutorial: Printf() with (and without) Processor Expert | MCU on Eclipse

a solution for printf (add a low level UART) but for sprintf there is no UART.  I just need to format a char array :

"

char a8char[50];

unsigned short u16titi ;

u16titi = 262390;

sprintf(a8char,"%hu",u16titi);

"

With librarian settings "ewl_hosted" sprintf works well but without multilink the application don't run...

 

How can I activate sprintf without UART ?

 

thank you in advance for your explanations.
