When a real UART (CONFIG_UARTx_SERIAL_CONSOLE) is selected as the system console while CONFIG_ESP32S3_USBSERIAL is also enabled (e.g. to keep /dev/ttyACM0 available as a secondary device alongside an external console UART), the unconditional #ifdef CONFIG_ESP32S3_USBSERIAL # define CONSOLE_DEV g_uart_usbserial #endif block silently redefines CONSOLE_DEV, clobbering the correct earlier definition that pointed it at the chosen UART device. Confirmed on real hardware (Seeed XIAO ESP32-S3): with UART0 selected as console and USBSERIAL also enabled, the board boot-looped on RTCWDT_RTC_RST every ~8s, never reaching NSH. With this fix, NSH comes up normally over UART0 and /dev/ttyACM0 remains available. Signed-off-by: Felipe Moura <moura.fmo@gmail.com> Assisted-by: Claude:claude-sonnet-5 |

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
