RE: 20230116-ubuntu-20.04-preinstalled-desktop-arm64是否预先安装了RKNN 2.0 、支持UVC免驱协议的摄像头吗
@bbsvs2000 有预装,相应工程包在/home/coolpi/目录。 UVC协议摄像头默认系统是支持的

RE: Coolpi 4b Ubuntu22.04 原生系统
@Twsuts
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 &

RE: How to use Coolpi 4b RTC
coolpi 4b 板载rtc时钟芯片,默认软件系统已配置支持,用户如需保存时钟信息,需要外接一个纽扣电池。在主板背面有预留可以焊接的位置。

瑞芯微新一代机器视觉方案RV1106及RV1103
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。

RE: 自动连接WIFI
@zhengbicheng said in 自动连接WIFI:
@ccjjww1222 您误会我的意思了,我的意思是你可以用电脑利用转接器连接Cool-pi开发板的串口。使用串口输入账号密码后就是命令行了。
他是想沿用树莓派预配置wifi信息,刷机自动连接wifi

RE: coolpi 4b support ov5647 camera module
暂时未重新打包刷机镜像,可以先独立更新内核驱动包。
coolpi@coolpi:~$ sudo dpkg -i coolpi-kernel_1.0.0_aarch64.deb coolpi@coolpi:~$ sync coolpi@coolpi:~$ sudo reboot
重启系统,如有连接ov5647摄像头,可以识别到video设备。
coolpi@coolpi:~$ sudo apt install v4l-utils coolpi@coolpi:~$ v4l2-ctl --list-devices rkisp-statistics (platform: rkisp): /dev/video18 /dev/video19 rkcif (platform:rkcif-mipi-lvds2): /dev/video0 /dev/video1 /dev/video2 /dev/video3 /dev/video4 /dev/video5 /dev/video6 /dev/video7 /dev/video8 /dev/video9 /dev/video10 rkisp_mainpath (platform:rkisp0-vir0): /dev/video11 /dev/video12 /dev/video13 /dev/video14 /dev/video15 /dev/video16 /dev/video17

RE: Keep going
@顾真牛 系统切换是支持的,这部分可以在boot分区修改extlinux.conf文件实现。理论上用户自行创建多个rootfs分区,通过相应分区label区分,切换系统也比较容易实现。
当然uboot源码我们也是开放的,大家都可以根据需要修改
