cubeide sprintf float error with FreeRTOS

[Hoang_Tran]

I trying to force some types of floats into string types. When using keil c, there is no problem, but when using Cube IDE, the program jumps to HardFault_Handler. I have allowed to use float with printf from newlib - nano in the tool setting. I only get this error when using FreeRTOS and if not using FreeRTOS then there is no problem. I tried both STM32f4 and H7 to get the same error.

Please help me .

thank all
