STM32cubeide printf error

[Hoang_Tran]

I started working with STM32CubeIDE recently. I use STM32f407VET6. I am having an error with the printf () function. When I call the function, the program will jump to HardFault_Handler (void). I have redirected the function using ITM_SendChar (* ptr ++) ;. When I made the error correction I noticed that the program calls puts instead instead of printf (). .

help me please

Do not replace printf. Replace __io_putchar or _write.

This is normal, GCC compiler does this when the printf format is a simple string.

Yes, I replaced the _write function above. But the program never went into the _write function.

Probably stack size to small.
