1. The .kasan.unused and .kasan.global sections contain compiler-generated data with the WRITE flag (.data..LASAN*), but the linker script placed them before .text without specifying a memory region. The linker could not put writable sections into the read-only ROM (rx) region, so it silently placed them at 0x40000000 in RAM, creating an extra LOAD segment that conflicts with QEMU virt's RAM layout and causes boot failure. 2. The .kasan.global should be placed before .data because .data patten (*(.data*)) includes .kasan.global pattern (*(.data..LASAN0)), and it cause kasan_global.py cannot find .kasan.global section to generate the g_global_region array. 3. Move .kasan.shadows from before .text to after .rodata. Placing it before .text causes .text to shift when .kasan.shadows transitions from empty (pass 1) to populated (pass 2+), preventing the multi-pass link addresses from converging. After .rodata it does not affect any upstream section addresses. 4. Add CMake post-build step to strip .kasan.unused and .kasan.global sections from the final binary, matching the Makefile build behavior. Signed-off-by: leisiji <2265215145@qq.com> |

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.
