感谢，买了V851SE开发板，正想学习NPU

大佬厉害，666666

值得好好学习！！！

@vecare_yu 请问解决了吗？

感谢大佬分享，帮忙解决了这个问题，我的系统是存储在eMMC里的，反正现在系统可以reboot成功了。
在mangopi开发板和自己做的开发板上均有这个错误，搞不清除是怎么回事？

@jr_online 大概率你改错地方了，正常就是改哪个，你看看你的环境对应的是哪个文件，linux修改的时候不能照搬路径的

预期功能已经实现 详细内容在下一篇

@livpo 非常有效，respect !

@yubeer 你好 请问你的这个问题解决了吗？

@amirhos_esm ./sample_rtsp -path /usr/bin/sample_rtsp_sc1718v_eth.conf

@whycanservice2 非常感谢您的回复。

我一直在参考 tplayerdemo，您说得对，它可以播放文件夹中的多个文件。

但是对于我的用例，我想在后台加载第二个视频，同时仍在播放第一个视频，然后无缝切换。

您知道这样做的任何示例吗？查看 tplayerdemo 和 tplayer，似乎它们实际上只能在 1 个层上一次处理 1 个视频。

我也尝试运行多个 tplayerdemo 实例，查看底层 tplayer 代码，似乎它总是绘制到同一层，因此我无法在不清除层缓冲区的情况下初始化 1 个 tplayerdemo。

任何帮助都将不胜感激。谢谢。

@y13616519006 正常

遇到了同样的问题，使用rndis向开发板传输大文件时就会报错，反向传输则没问题，详细日志如下

@awwwwa 我用的是acuity-toolkit-binary-6.6.1，确实存在split算子有一些问题。不过我最后修改算子，解决了这个问题，用slice算子替换了split算子。

@minjialong 本人已解决

V851S是不是也是一样的方法呢

工具代码已开源:
LzmaLib-aw-melis

这个是交叉编译工具链没找到，确认下有这个文件吗
`

@aw2022 我也遇到一样的问题，解决了吗

@null037 谢谢你哈

谢谢楼主提供资源

node 需要systemd，默认是busybox应该不行，可以移植一个ubuntu上去

@bigfly 大佬确实大佬，bilbil有，

@yunchawaishi 看 Depends on: ... VGA_CONSOLE 这个，[=n] 就是没打开，要先打开才显示选项

@awwwwa does anyone have a schematic of this? my question is 3v3 or 1v8 oscillator. I guessed 1v8 since VCC-PLL is 1v8. anyone know for sure? anyone doing this in a production unit. trying to avoid simple crystal capacitance matching etc. prefer using oscillators.

@sofia 能问下SD nand用的是什么型号芯片吗？

yes. where is the latest version?

@godzhou0909 基地址不一样吧，改下设备树 di 的 reg 的起点

@aiit111 在设备树里关掉吧

@zhuangjinfu 只要source, lunch后，在任意路径下执行 mkernel 这个指令，就可以编译内核了

@slearn 是一样的

@antbot 1719989967848.jpg

@casojie

重新编译内核

make kernel_menuconfig

勾上
Device Drivers -> Pin controllers -> Allwinner SOC PINCTRL DRIVER -> pinctrl sunxi debugfs driver

@jhyzero 请问解决了吗

@liuqiang 关闭readonly 是在Enable UBI下面

如何解决的 ？ 能否详细说下

@ppdbb 用xfel试试，或者用量产工具试试

@bugwtq 这就不知道了，没用过，但从错误看，可能涉及到apache的源码，是数据类型不匹配……没有提示依赖错误

@whycan 在 buildroot编译报错 中说：

@dql2016

BR2_PACKAGE_HOST_UBOOT_TOOLS

b37b5106-34f0-4457-b267-cd58f9347c29-image.png

这个选项开起来.

请问这个哪个文件

我也遇到了编译QT5 无法打包所有qt so库的情况。
经过调试发现
是最后打包制作 rootfs.img 时 自动将 脚本认为无用的 文件资源 库 给移除掉了。所以导致最终目标系统没有包含进去。

源码 build 目录 找到 reduce-rootfs-size.sh 脚本
找到 downsize_rootfs 函数，注释掉里面的几个 remove函数

6aad5b64-c79f-446e-988f-fac675fc2eee-image.png

具体打包无效原因在。

@whycanservice2 明白了,谢谢前辈!

@yuqingli 我也很纳闷，驱动正常，估计是tplayerdemo对fb0的缓存有要求，暂时还不知道怎么改。tinyversion的v851se只有spi屏幕，不知道能不能tplayerdemo播放。

@jhogy 直接网络通信啊 tpc udp http mqtt 等等 其他协议都可以。只要能ping 的通，网络不是随便完吗

@jr_online 修改配置 buildroot 可以加入自己的根文件系统路径覆盖

@xucw15990192241
是不是EMMC脚被SPI占用了，在设备树文件禁止SPI就可以了?另外量产卡怎么制作，我想通过量产卡烧录程序到spi_nand

视频大于800*600，T113，小于F133

@jingyan 感谢，已经发现了不行

@rockenergytech 大佬您好,我在板级的rootfs目录下新建文件,如何生成rootfs.img哪.

【自问自答】
在启动烧写工具看到 Clos image OK以后，按住FEL，同时按复位键或插入USB，这个时候FEL不能放，直到界面有反应再放FEL。（之前T113用惯了，通常是马上就放手）

不过100ask的回复效率还是要提高一下。我找了论坛里的好多相关问题，都是没有找到回复。

@韦老师

我也遇到同样的问题，停在OK

@wyljkl 大概率 是由于屏关机后没有使用 0x28 0x10 代码让屏进入休眠后关闭。然后 应当在启动时候 先 给刷屏 后给背光，关闭时候 先关闭背光再停止刷新 然后让屏休眠。按照这个步骤 应该不会再出现残影了。

@vincent1 在 V853 openwrt系统，make menuconfig打开Allwinner > Visiol>LibAWIspApi 报错 中说：

Only the G value was inexplicably high

如何修复G值？

@null037 我遇到了类似的问题，请问你后来是怎么解决的？

谢谢 ，我遇到一个问题， 问了创龙的人他们说是打包的时候生成的

@whycan 大佬，请问t113-i做mipi-dsi屏幕驱动时，发现framebuffer的起始地址为0，深究了一下发现设备的mapping->base也是0，不知道是不是哪里配置没有打开导致没有分配到，能提供一下思路吗。我是用longan的sdk的之前在d1-h的tina系统是可以实现的，如果是sdk 的问题的话能麻烦提供一下能适配T113-i的tina sdk吗？卡了好久了，感激不尽

@null037谢谢大佬！😬

我也遇到了同样的问题,

可能我的虚拟机为解决这个问题，改了很多地方的原因吧，重新装了虚拟机，删掉Makefile文件中的空格用tab键，我这边也解决问题了
感谢 @caochenxin
