The esp32s3-devkit:usbmsc config uses CONFIG_ESPRESSIF_SIMPLE_BOOT, so
the image is packaged with "esptool elf2image --ram-only-header". With
esptool v5.2.0, that path asserts that each flash segment satisfies
(f.tell() + 8 + BOOTLOADER_FLASH_OFFSET) % IROM_ALIGN
== segment.addr % IROM_ALIGN
When .flash.text lands right on a 64 KB (IROM_ALIGN) boundary the
assertion cannot be satisfied and elf2image fails with AssertionError,
even though NuttX itself links cleanly.
usbmsc is a plain C test and does not need the C++ runtime. Disabling
CONFIG_HAVE_CXX / CONFIG_HAVE_CXXINITIALIZE moves .flash.text off the
IROM_ALIGN boundary so the SIMPLE_BOOT image can be generated, without
changing the boot mode or the test's intent.

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.
Contributing
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.
