assertios "REENT malloc succeeded" failed, RTOS and printf

[EthanMankins]

My project is fully working with touchgfx and FreeRtos; however, I need to add in a printf("%f") statement. Whenever I use %f i get the following error:

assertios "REENT malloc succeeded" failed: file "/build/gnu-tools-for-stm32_12.3
.rel1.20240926-1715/src/newlib/newlib/libc/stdlib/dtoa.c", line 239

 I have used printf("%d") fine. I tried following others advice of generating a new project and copying over the sysmem.c file to the new version of sbreak, but when I do that my project no longer works as expected.

Is there another way to fix specifically the printf issue without having to risk the integrity of the rest of my project?

Hello @EthanMankins 

Please ensure that you are enabling the use of floating point with printf in your STM32CubeIDE project.
