  这是阻塞系统运行？还是后台运行作为开机动画？

  我试了分别在/etc/profile、/home/coolpi/.profile文件尾增加qt demo是可以的

  sudo apt install qtbase5-examples coolpi@coolpi:~$ cat /etc/profile # /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...). if [ "${PS1-}" ]; then if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then # The file bash.bashrc already sets the default PS1. # PS1='\h:\w\$ ' if [ -f /etc/bash.bashrc ]; then . /etc/bash.bashrc fi else if [ "`id -u`" -eq 0 ]; then PS1='# ' else PS1='$ ' fi fi fi if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -r $i ]; then . $i fi done unset i fi #echo "coolpi" | sudo -S /usr/lib/aarch64-linux-gnu/qt5/examples/gui/analogclock/analogclock coolpi@coolpi:~$ coolpi@coolpi:~$ cat ~/.profile # ~/.profile: executed by the command interpreter for login shells. # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login # exists. # see /usr/share/doc/bash/examples/startup-files for examples. # the files are located in the bash-doc package. # the default umask is set in /etc/profile; for setting the umask # for ssh logins, install and configure the libpam-umask package. #umask 022 # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi # set PATH so it includes user's private bin if it exists if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi # set PATH so it includes user's private bin if it exists if [ -d "$HOME/.local/bin" ] ; then PATH="$HOME/.local/bin:$PATH" fi echo "coolpi" | sudo -S /usr/lib/aarch64-linux-gnu/qt5/examples/gui/analogclock/analogclock coolpi@coolpi:~$

  因为不是后台运行，重启后会阻塞桌面系统显示窗口。此时可以通过键盘ctrl+alt+f6切换到终端命令行进行恢复修改操作。

  也可以后台运行测试

  vim ~/.profile ... echo "coolpi" | sudo -S /usr/lib/aarch64-linux-gnu/qt5/examples/gui/analogclock/analogclock &

  @zhengbicheng 我也期望有追踪，deepsort就可以了，利用CPU算，比较耗费资源，特别是多个摄像头追踪，NPU算比较好

  @george 確實是 bootloader 沒有更新到，謝謝！

  建議是否開一個 for Debian / Armbian 的 討論區？ 這樣相關文章也會比較找到。

  The Yocto Project (YP) is an open source collaboration project that helps developers create custom Linux-based systems regardless of the hardware architecture.

  The project provides a flexible set of tools and a space where embedded developers worldwide can share technologies, software stacks, configurations, and best practices that can be used to create tailored Linux images for embedded and IOT devices, or anywhere a customized Linux OS is needed.

  step1:

  git clone https://gitee.com/yanyitech/openwrt.git cd openwrt ### Quickstart 1. Run `./scripts/feeds update -a` to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run `./scripts/feeds install -a` to install symlinks for all obtained packages into package/feeds/ 3. Run `make menuconfig` to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run `make` to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

  RV1106 is a highly integrated vision processor SoC for IPC, especially for AI related application.

  It is based on single-core ARM Cortex-A7 32-bit core which integrates NEON and FPU. There is a 32KB I-cache and 32KB D-cache and 128KB unified L2 cache. The build-in NPU supports INT4/INT8/INT16 hybrid operation and computing power is up to 0.5TOPs. In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.

  RV1106 introduces a new generation totally hardware-based maximum 5-Megapixel ISP (image signal processor). It implements a lot of algorithm accelerators, such as HDR, 3A, LSC, 3DNR, 2DNR, sharpening, dehaze, gamma correction and so on. Cooperating with two
  MIPI CSI (or LVDS) and one DVP (BT.601/BT.656/BT.1120) interface, users can build a system that receives video data from 3 camera sensors simultaneous. The video encoder embedded in RV1106 supports H.265/H.264 encoding. It also supports multi-stream encoding. With the help of this feature, the video from camera can be encoded with higher resolution and stored in local memory and transferred another lower resolution video to cloud storage at the same time. To accelerate video processing, an intelligent video engine with 22 calculation units is also embedded.

  RV1106 has a build-in 16-bit DRAM DDR3L capable of sustaining demanding memory bandwidths. It also integrated build-in RTC, POR, audio codec and MAC PHY.

  新一代机器视觉方案RV1106及RV1103，两颗芯片在NPU、ISP、视频编码、音频处理等性能均有显著升级，具有高集成度、高性价比、低待机功耗的特点。RV1106及RV1103为普惠型方案，旨在助力更多行业伙伴高效实现机器视觉产品的研发及落地。
