sprintf not functioning correctly

[christopher_hes]

I am working on a project in MCUXpresso that was originally written in code warrior. I am having difficulty using a sprintf() function and the problem seems to be with MCUXpresso. I have checked that I am using the original compiler and I am using the Redlib semihost C library.  Below is the code:

char tString[50];

float current = 1.2;

sprintf(tString, "%3.0f",current);

After stepping through this code, the first three entries of tString are 32 ' '.  What could be causing this issue?

Are you using RedLib (the default)?

If yes, see https://community.nxp.com/docs/DOC-342727 

I hope this helps,

I am using RedLib,  I followed the instructions in the article you have referenced and when I opened that window the only directive from the article was PRINTF_FLOAT_ENABLE=0.  I modified the directives as seen below and this has still not solved the issue.  Additionally, I have included a snip of the tString after sprintf is called.

I see you still have that CR_INTEGER_PRINTF in the list of defines. Remove it.

I hope this helps,

This seems to have solved the issue, thank you.  I additionally found that it works using the NewLibNano library and selecting enable printf float and enable scanf float in the Managed Linker Script.
