Project:Branches: catalin/rtems:stm32f4_bsp_fix to rtems/rtos/rtems:main Author: Catalin Miron ## Summary BSP_output_char used Console_Port_Tbl, which is only allocated by the legacy console_initialization(). With the simple console driver (e.g testsuites/samples/hello) or for any printk() before device driver initialization this resulted in a NULL pointer dereference. The USART was also never initialized in this case. Fall back to Console_Configuration_Ports while Console_Port_Tbl is not yet set up. Initialize the console USART in a BSP_START system initialization handler and laizly on the first character. Provide BSP_poll_char for getchark(). Disabled STM32F4_ENABLE_USART_3 by default because not all stm32f4 boards have this port. Added PORT_COUNT \> 0 guards in case no USART is configured in config.ini. Tested on STM32F411RE Nucleo board by running hello.exe ## AI Details <!--Make sure you have read our statement at https://www.rtems.org/generative-ai/--> ### Prompt used Not a single prompt, it was an iterative process. ### AI model used Claude Opus 5.5 ### How AI was used for the contribution - [x] Formatting - [ ] Test creation. - [x] Code comments. - [ ] The entire contribution was generated using AI - [ ] AI code completion such as Copilot in VSCode.
