UDP and PKT will hold the dev lock and conn lock when calling back the protocol stack from the network dirver. At this time, if the poll_notify notifies usrsock_server and executes poll_teardown, a conn double lock will appear. so we changed the lock to a recursive lock sched_dumpstack /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/Libs/libc/sched/sched_dumpstack.c:71 __assert /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/libs/libc/assert/lib_assert.c:49 nxsem_wait_slow /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/sched/semaphore/sem_wait.c:102 (discriminator 1) nxmutex_lock /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/include/nuttx/mutex.h:514 udp_pollteardown /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/udp/udp_netpoll.c:278 usrsock_rpmsg_poll_setup /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/usrsock/usrsock_rpmsg_server.c:1232 usrsock_rpmsg_poll_cb /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/usrsock/usrsock_rpmsg_server.c:1299 poll_notify /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/fs/vfs/fs_poll.c:296 udp_poll_eventhandler /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/udp/udp_netpoll.c:105 devif_conn_event /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/devif/devif_callback.c:481 udp_callback /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/udp/udp_callback.c:324 udp_input_conn /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/udp/udp_input.c:150 ipv4_in /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/devif/ipv4_input.c:425 ipv4_input /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/net/devif/ipv4_input.c:533 tun_net_receive_tun /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/net/tun.c:574 tun_net_receive_tun /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/net/tun.c:574 file_writev_compat /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/fs/vfs/fs_write.c:89 rpmsgdev_write_handler /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/misc/rpmsgdev_server.c:354 rpmsg_virtio_process_rx_buffer /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/rpmsg/rpmsg_virtio.c:256 rpmsg_virtio_rx_worker /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/drivers/rpmsg/rpmsg_virtio.c:291 work_dispatch /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/sched/wqueue/kwork_thread.c:233 work_thread /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/sched/wqueue/kwork_thread.c:293 nxtask_start /home/work/ssd1/workspace/MiRTOS-062-dev-system-CI/nuttx/sched/task/task_start.c:99 Signed-off-by: zhanghongyu <zhanghongyu@xiaomi.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.
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.
