set_intr_wrapper() allocates a new intr_handle_data_t from the kernel heap each time the Wi-Fi driver calls it, and the driver calls it on every esp_wifi_start() -- twice per start on esp32s3 -- not only the first time. clear_intr_wrapper() is a no-op, so the IRQ still holds the handle from the previous start: esp_set_handle() refuses to replace it with -EINVAL, the return value is ignored, and the new block is lost. Any application that stops and restarts Wi-Fi to save power therefore loses a few bytes of kernel heap per cycle, without bound. Look up the vector descriptor first, then reuse the handle already registered for the IRQ and only allocate and register one when there is none. A failed descriptor lookup no longer touches the registered handle. The same code is present in the esp32, esp32s2, esp32s3, esp32c3 and esp32c6 Wi-Fi adapters; all five are fixed the same way.

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.
