When the ipc buffer is obtained for the first time due to insufficient space, it waits due to insufficient ipc buffer. At this time, if rptun recursively operates the next ipc request, the ipc buffer will be reused, but it has been released at this time. 0 file_read (filep=filep@entry=0x20596738, buf=buf@entry=0x205d4358, nbytes=1560) at vfs/fs_read.c:86 1 sensor_rpmsg_push_event_one (dev=0x20558f70, dev@entry=0x2058fc80, stub=stub@entry=0x20596720) at sensors/sensor_rpmsg.c:799 2 sensor_rpmsg_alloc_stub (dev=dev@entry=0x2058fc80, ept=ept@entry=0x20558f08, cookie=<optimized out>) at sensors/sensor_rpmsg.c:552 3 sensor_rpmsg_sub_handler (ept=0x20558f08, data=0x204849c0, len=51, src=<optimized out>, priv=0x20558f00) at sensors/sensor_rpmsg.c:993 4 sensor_rpmsg_ept_cb (ept=<optimized out>, data=<optimized out>, len=<optimized out>, src=<optimized out>, priv=0x20558f00) at sensors/sensor_rpmsg.c:1186 5 rpmsg_virtio_rx_callback (vq=<optimized out>) at open-amp/lib/rpmsg/rpmsg_virtio.c:605 6 virtqueue_notification (vq=<optimized out>) at open-amp/lib/virtio/virtqueue.c:711 7 rproc_virtio_notified (vdev=vdev@entry=0x20558c98, notifyid=notifyid@entry=4294967295) at open-amp/lib/remoteproc/remoteproc_virtio.c:433 8 remoteproc_get_notification (rproc=rproc@entry=0x2054ff34, notifyid=notifyid@entry=4294967295) at open-amp/lib/remoteproc/remoteproc.c:1002 9 rptun_worker (arg=0x2054ff30) at rptun/rptun.c:339 10 rptun_notify_wait (rproc=<optimized out>, id=<optimized out>) at rptun/rptun.c:543 11 remoteproc_virtio_notify_wait (priv=<optimized out>, id=<optimized out>) at open-amp/lib/remoteproc/remoteproc.c:907 12 rproc_virtio_notify_wait (vdev=<optimized out>, vq=<optimized out>) at open-amp/lib/remoteproc/remoteproc_virtio.c:176 13 rpmsg_virtio_notify_wait (vq=<optimized out>, rvdev=0x2054ff78) at nuttx/include/openamp/rpmsg_virtio.h:162 14 rpmsg_virtio_get_tx_payload_buffer (rdev=0x2054ff78, len=0x20558f90, wait=<optimized out>) at open-amp/lib/rpmsg/rpmsg_virtio.c:404 15 rpmsg_get_tx_payload_buffer (ept=ept@entry=0x20558f08, len=len@entry=0x20558f90, wait=wait@entry=1) at open-amp/lib/rpmsg/rpmsg.c:207 16 sensor_rpmsg_push_event_one (dev=0x0, dev@entry=0x20590d60, stub=stub@entry=0x20596720) at sensors/sensor_rpmsg.c:783 17 sensor_rpmsg_alloc_stub (dev=dev@entry=0x20590d60, ept=ept@entry=0x20558f08, cookie=<optimized out>) at sensors/sensor_rpmsg.c:552 18 sensor_rpmsg_sub_handler (ept=0x20558f08, data=0x20483700, len=49, src=<optimized out>, priv=0x20558f00) at sensors/sensor_rpmsg.c:993 19 sensor_rpmsg_ept_cb (ept=<optimized out>, data=<optimized out>, len=<optimized out>, src=<optimized out>, priv=0x20558f00) at sensors/sensor_rpmsg.c:1186 20 rpmsg_virtio_rx_callback (vq=<optimized out>) at open-amp/lib/rpmsg/rpmsg_virtio.c:605 21 virtqueue_notification (vq=<optimized out>) at open-amp/lib/virtio/virtqueue.c:711 22 rproc_virtio_notified (vdev=vdev@entry=0x20558c98, notifyid=notifyid@entry=4294967295) at open-amp/lib/remoteproc/remoteproc_virtio.c:433 23 remoteproc_get_notification (rproc=0x2054ff34, rproc, notifyid=notifyid@entry=4294967295) 24 rptun_worker (arg=0x2054ff30) at rptun/rptun.c:339 25 rptun_thread (argc=<optimized out>, argv=<optimized out>) at rptun/rptun.c:375 Signed-off-by: dongjiuzhu1 <dongjiuzhu1@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.
