Hello,
We are using STM32L552ZET6Q MCU in our project. Here we are using only 3 UART Pheripherals, 2 LED output GPIOs.
Here We attached the CUBEMX .ioc file of the our project. After the code generation from the STM32CUBEMX, we complete our's own program for the project.
In this code we are using LPUART1 and USART2 to communicate a PC for Serial monitoring. UART4 used to Serial communication with another one MCU. Two LED GPIO used to indication purpose.
After the code completion we flashing the code to the STM32L552ZET6Q MCU and it works fine. But most of the time, the controller not working properly, it means the MCU not Communicate with PC and Another one MCU. After the reset Power it will working properly. We cant find whats the problem occure in that time. We doubt this controller may goes to sleep mode or standby mode or shutdown mode maybe. Because the controller was Specially for developed to Low power applications.
Kindly help us to find issue and resolve it.
