TinyVision 制作的高清 1080P USB 摄像头

[YuzukiTsuru]

tinyvision_webcam.7z

解压后使用 dd/win32imager 烧录 TF 卡启动即可

@YuzukiTsuru 非常好的项目，这正是我一直在努力实现的目标，您使用的是 NDA 下的专有 sdk，而不是开源 tina linux sdk，不是吗？ 否则你如何让视频编码器工作？

[kanken6174]

@yuzukitsuru 这是一块非常好的板，您认为这个版本的 SDK 可以适应在 V851S（非 SE）上以同样的方式工作吗？

[YuzukiTsuru]

@kanken6174 一样的，你可以直接替换我的rootfs运行

[bardi4567]

@yuzukitsuru I can't get the SDK from "https://sdk.aw-ol.com/git_repo/V853Tina_Open/manifest.git" even with LV3!
The "repo sync" doesn't do anything.
Could you please share another path ?
Thx

@bardi4567 what is the error log

[kanken6174]

@yuzukitsuru 您是说，如果我只是覆盖适用于 V851S 的 .img 文件的 squashfs 分区，它将与您提供的 V851SE 特定 iamge 文件一起使用？ 因为我尝试过，它导致了内核恐慌...

该映像是使用默认设置 (squashfs) 的 yuzukilizard BSP/openwrt 从默认的 V853 sdk 编译的（按原样使用时有效），我使用该命令来替换 rootfs squashfs：

sudo dd if=/dev/sdf4 of=/dev/sdi4 bs=4M conv=fsync

或者这不是您所说的“替换rootfs”的意思？

[bardi4567]

@awwwwa No error at all.
It just stucks at downloading the first item (1/74) and never downloads anything !

[kanken6174]

@bardi4567 repo init -u https://sdk.aw-ol.com/git_repo/V853Tina_Open/manifest.git -b master -m tina-v853-open.xml
然后
repo sync
非常适合我，要么您的存储库配置不正确，要么您有一些文件权限问题，无论哪种方式，您都应该为您的问题创建一个单独的主题，因为它与本主题（tinyvision 开发板）无关！

@yuzukitsuru Hello, how to enable USB as host under OpenWrt 23.05, is this configuration in dts file correct?:

&usbc0 {
device_type = "usbc0";
usb_port_type = <0x1>;
usb_detect_type = <0x1>;
usb_detect_mode = <0x0>;
usb_id_gpio;
usb_det_vbus_gpio;
/* det_vbus_supply = <&usb_power_supply>; */
usb_regulator_io = "nocare";
usb_wakeup_suspend = <0>;
usb_serial_unique = <0>;
usb_serial_number = "20080411";
status = "okay";
};

the device connected is not detected, also trying to list the usb devices this is the result:

please your comments.

Thanks!

@YuzukiTsuru 我无法让它在 V851S 上工作，你所说的 “替换 rootfs” 到底是什么意思？（我不小心错误地将这条消息发送到您的另一篇帖子，对此表示抱歉）

[xzhang]

请问有patch或者源码可以参考是如何实现的吗？

[Gambler]

您好，请问您是怎么做到的？
如何编解码？如何通过usb传输的呢？谢谢

大佬，851想做mipi摄像头实时显示在5寸的mipi屏幕上可以做到吗
