### Description This month, I discovered the NuttX project when I was searching for a versatile RTOS that supports multiple architectures. To be honest, this project is very interesting for me because I can use it in my DIY and other applications. I have read the NuttX Documentation and watched the video playlist called "NuttX Get Started" on YouTube. However, I have run into a problem. When I am following all the instructions from the video (https://www.youtube.com/watch?v=rgZJPZh_po8), I succeed, but it is mindlessly repeating steps without truly understanding what I am doing. I want to learn NuttX properly because I need to use Nuttx in my own projects. The knowledge I have gained from the video is not enough to implement anything beyond copying the example project. To solve this, I tried exploring the NuttX Documentation. While it covers OS components, license information, implementation details well, I miss transferring the knowledge gained from the implementation of a specific project (even if just by repeating the actions from the video) to a more general case. For example, after watching a video on how to configure SPI-flash, I would be able to apply this experience to configure NOR-flash on another hardware. The "Getting Started" section only covers basic compilation (nuttx.bin), nothing more. I set myself the task, guided by the knowledge gained from this video, to try to do the same thing but on a different microcontroller from STMicro. My Test Project: I want to change the NSH console from the default /dev/ttyS0 (UART1) to /dev/ttyACM0 (USB CDC/ACM) on an STM32F411 (Black Pill) board. What I’ve Tried: Successfully replicated the USB console setup on STM32F103 (as shown in the video). Tried the same steps on the STM32F411 (with adjusted configure.sh settings). Compilation succeeds, but /dev/ttyACM0 does not appear on my Debian host (dmesg/lsusb show nothing). My configuration was: ./tools/configure.sh stm32f411-minimum:nsh CONFIG_STM32_OTGFS=y CONFIG_USBDEV=y CONFIG_CDCACM=y CONFIG_CDCACM_CONSOLE=y CONFIG_NO_SERIAL_CONSOLE=y CONFIG_BOARDCTL_USBDEVCTRL=y CONFIG_CONFIG_NSH_USBCONSOLE=y CONFIG_CONFIG_NSH_USBCONDEV=/dev/ttyACM0 And I sure that the USB pins are worked properly and there is no problem with any hardware on the board. I hope you now understand my struggle — I feel like I have hit a dead end in learning NuttX. Could you please: Explain what I might be missing in the configuration? Suggest an approach for working with new microcontroller or untested configurations: What steps should I take to understand the full setup (kconfig, source code, application settings, etc.)? Or it could it be a bug? Any advice would be greatly appreciated! ### Verification - [x] I have verified before submitting the report. -- This is an automated message from the Apache Git Service.
