Facing problem in communicating with STM32 MCU on custom PCB through minicom on linux. PC is detecting /dev/ttyACM0 and opens up minicom but unable to see all the initializations and processes going on in MCU as in the discovery kit STM32MP157C-DK2.

Hi @RKaur.1​ ,

Could you give some details of differences between your custom PCB and DK2 ?

Are you using STLINK virtual port for console ?

Did you follow recommendation in AN5031Getting started with STM32MP15 Series hardware development ( AN5031.pdf ) around UART settings ?

Did you properly generate and complete DT for your custom HW ? ( console UART properly declare )
