I'm using stm32u5 and azurertos system. In a thread, I do this instruction <sprintf(g_test,"phase%d\n",g_frame);> where <char g_test[20]> and <u8 g_frame> and a hard fault is generated. Any suggestion, please?

Look at the machine level instructions and register at the fault. The ​processor provides a lot of information to help identify what type of failure is occurring.
