@whycanservice2 谢谢佬，我把我的镜像放到MQ的那个小板子上跑了一下，也是跑不完每次会卡在同一个地方，但是这个地方已经比MMC 的device 2 not found 多跑了几百行代码。我的板子和MQ的板子都没有外接任何的设备，各模块电源都一致，都是用PB6 PB7 作为输出串口，所以我镜像和硬件都有毛病，这下难搞了👼 0a0ba800-0315-402d-9bc8-e4964849a5fb-image.png

驅動程式在哪我找不到？

@allwinnercoding 硬解？能不能具体说说如何做。现在tplayerdemo默认不是硬解吗

@zzz555 The clock signal may be operating at a speed outside the bandwidth of your oscilloscope. Check the Hz setting of your clock, and ensure it is less than the bandwidth of the oscilloscope (likely 100 MHz).

If it is higher, then the signal will be attenuated. Configure the scope to be AC-coupled and try increasing the scope gain to see a faint signal.

@ddrddr 跟踪学习一下

@awwwwa 找到问题了，核心电压原本是0.9v给到0.95就正常了

发现OpenWRT已经内置了Orange Pi PC 支持了。

你要注意一下，这儿的 spi 速度值并不是可以随便设置的！ 因為 cpu 除频后会配不上！ 会跳到默认的 10Mhz 的速度。

建议你可以在 .... spi 中，加打印，看看你那值是否可以通过！

/driver/spi/spi-sunxi.c 中

/* set spi clock */ static void spi_set_clk(u32 spi_clk, u32 ahb_clk, struct sunxi_spi *sspi) { u32 spi_test = 100000000; u32 get_spi; dprintk(DEBUG_INFO, "set spi clock %d, mclk %d\n", spi_clk, ahb_clk); for(spi_test = 50000000; spi_test >= 20000000; spi_test -= 1000000) { clk_set_rate(sspi->mclk, spi_test); get_spi = clk_get_rate(sspi->mclk); printk("spi_test %d == get %d \n", spi_test, get_spi); }

像我以 100Mhz 到 80Mhz ， 每 1Mhz 做变化！

你好，请问问题解决了吗，我这也遇到类似的问题

你好，我也遇到了相同的问题。您最后怎么解决的

@q1215200171 这个有用

可以访问：https://github.com/DongshanPI/buildroot_100ask_t113-pro/blob/master/docs/07-Buildroot-SDK_DevelopmentGuide.md

使用buildroot-SDK编译构建系统 简介 此套构建系统基于全志T113-S3芯片，适配了buildroot 2022lts主线版本，兼容了百问网的项目课程以及相关组件，真正做到了低耦合，高可用，使用不同的buildroot external tree规格，讲不同的项目 不同的组件分别管理，来实现更容易上手 也更容易学习理解。 安装必要依赖包 ubuntu-18.04

运行环境配置： 此系统基于ubuntu18.04进行验证，在之前的基础之上还需要安装以下必要依赖

book@100ask:~$ sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev xsltproc libxml-parser-perl mercurial bzr ecj cvs unzip lib32z1 lib32z1-dev lib32stdc++6 libstdc++6 libncurses-dev u-boot-tools -y

参考

bb10ced5b443c6b7af2cf52871b987406faa37b9_2_690x358.png

修改编译指定的配置文件

book@100ask:~/buildroot-100ask_t113-pro/buildroot$ make BR2_EXTERNAL="../br2t113pro ../br2lvgl ../br2qt5" 100ask_t113-pro_sdcard_qt5_defconfig book@100ask:~/buildroot-100ask_t113-pro/buildroot$ make V=1

最终编译生成一个 sdcard.img 烧录至开发板内 启动，就包含了 qt lib库等，同时QT 环境 也会在 buildroot源码根目录下 的 output/host内。

用adb push 或者U盘传到根文件目录下的/usr/lib/目录下

我也遇到这个问题 跟楼主是一样的 希望大佬们帮助解决一下
如果用aplay 也是这样

# aplay /root/test.wav ALSA lib pcm_hw.c:2021:(_snd_pcm_hw_open) Unknown field slave aplay: main:828: audio open error: Invalid argument

1、第一次烧录成功了，证明你的flash驱动应该是支持这颗nand的，所以可以烧进去
2、但烧录进去不代表你flash驱动中的ID配置一定是正确的，有可能你拿到的flash驱动中对这颗物料的参数配置（坏块标记位、oob区域划分、ecc校验能力等）配置不正确，导致你第一次烧录的时候，在这颗flash上误标记了bad block，故后续烧录或者启动会提示很多的“bad block......”
3、建议找一个常用型号的flash，先替换上去，看下是否能正常启动，可以试一下这款（MX35LF1GE4AB），这款在很早之前的驱动已经是支持的了

@ddrddr 解决了吗？我跟你的情况一样，我的能ping通自己（127.0.0.1）

内核配置去掉宏：CONFIG_STACKPROTECTOR和CONFIG_STACKPROTECTOR_STRONG。

@shz18877605430 先确认一下T113上使用的 工具链类型是什么，是否有硬浮点支持，还是使用musl C库，如果一致，确认一下 你编译的这个程序是否有相应的 .so 动态库/依赖需要配合着 才能运行！

@bigfly colorbar正常吗

udp --- 用户数据报协议，是一个无连接的简单的面向数据报的运输层协议。
udp不提供可靠性，它只是把应用程序传给IP层的数据报发送出去，但是并不能保证它们能到达目的地。
udp在传输数据报前不用在客户和服务器之间建立一个连接，且没有超时重发等机制，故而传输速度很快。
udp是一种面向无连接的协议，每个数据报都是一个独立的信息，包括完整的源地址或目的地址，它在网络上以任何可能的路径传往目的地，因此能否到达目的地，到达目的地的时间以及内容的正确性都是不能被保证的。

udp通讯流程很简单，具体步骤如下：

@ganhx 好的，谢谢您了🤝

@kayano_ai
示波器看下 pclk,hsync,vsync几个频率对不对。

正常来说都是fb插件，可以尝试手动开启光标渲染

@gadyellow 在 如何在全志t113-i系统中，添加adb的登录密码 中说：

@whycan 是t系列的开发板没有考虑到吗？我在论坛里面看到了有关r系列相关的adb登录密码的修改r系列adb登录密码配置

就是按这个帖子修改adbd源码

搞定了吗？我用主线Linux驱动H616时也遇到了hdmi的问题，我按照orangepi的源码配置了设备树，也设置了内核配置：8bfa38a2-3c79-4fd1-8063-3b094553205f-image.png

屏幕上没有任何显示，有知道怎么配置的，望指导指导，谢谢！

@jinxiangwzh 不需要，USB3.0支持OTG

这通常是由于kernel更新而defconfig没有更新导致的，需要同步更新defconfig

@lancer make -j1 看看报错，这样看不到

坑死。 刚发现， 8189竟然没蓝牙

@zh834773979 解决了，tina的logo流程跟标准流程不太一样，首先uboot的设备树中LCD和DISP相关配置要正确，然后在lichee/brandy-2.0/u-boot-2018/configs/sun8iw20p1_uart3_defconfig配置文件中打开下面几个配置0f747a8e-88e2-4a83-9104-26968ccbed17-image.png 应该就可以了

@lancer 指的是预置自己的程序到rootfs分区吧？
如果是的话，参考package下面找个简单的工程自己添加并编译打包到文件系统。

进入lichee->brandy-2.0->u-boot-2018->configs
修改文件sun8iw20p1_uart3_defconfig
这个可以参考D1S的文件修改，其实这个文件就是少了屏幕，logo一段，从D1S上复制过去就可以了

@awwwwa 刚测试，重载 img, 就可以了

@awwwwa 嗯！ 貌似console的映射问题导致的。还在查找原因中

libopencv_highgui.so.4.8.0: file not recognized: File format not recognized

opencv不是交叉编译的

试试使用Ubuntu 14.04

@gonboy 换这个帖子里的驱动，芒果仓库里的摄像头驱动用不了的

D1-H （MQ-Pro）驱动 OV5640 摄像头
https://bbs.aw-ol.com/topic/4017/share/1

@fresird Windows 自带有的。

@awwwwa 感谢大佬的回复，我通过分析 build/pack 使用 ./build.sh packraw
找到了下面那个最终生成的命令

fded34af-2f9f-46d8-8648-5b2d5a9d9b93-image.png
然后把 programmer_img 丢进 buildroot 打包目录，直接编译打包，生成的镜像就可以直接用啦！
bb1056bc-0d52-41b5-bb02-b1c10b7e6b3b-image.png

sunxi_gpt这个我学习一下 怎么融进去 让他自己转换打包。

不得不说，这个 programmer_img 很强大，但是里面怎么实现的我很好奇，当时修改了各种 genimage.cfg的分区类型和头部都不行。

@dort91011 hello，我也遇到了同样的问题,请问您最后怎么解决的

怎么没有T113-I的芯片卖

目前可以购买 Sipeed 提供的 R329开发板，官方开发板已经停止售卖了。

@null037 这个问题你解决了吗？

@null037 给大伙分享一下测试镜像：tina_t113-100ask_uart3.img

@whycanservice 您好，请问[ 1.349938] sunxipart: failed to parse sunxi_gpt!这个是没有手动选择nor flash的原因吗？

@zzwquanzhi 解决了吗？遇到同样的问题

@godzhou0909 linux的补丁
di110.c di_utils.c
kernel\linux-5.4\drivers\char\sunxi-di\common
kernel\linux-5.4\drivers\char\sunxi-di\drv_div1xx
替换了这两个文件

@atms2013 设备树，lcd部分

@flyn_aw 0.5ptich 间距的U 建议显微镜

@newcastle 失败报错什么？没有进入初始化流程吗

F133只支持检测0-1.8v，精度很低的，速度也慢
当普通adc可能不太够用，如果只是采集个电压值还可以

@whycan 别的总线上block read也都不可以

@flyn_aw 我的解决了，rst接了电子到gnd，电压信号过低，去掉就可以了

@haolisheng 我的正常，已经可以进入TINA系统了

@whycanservice
所以目前来看应该只有两个办法了
1、PC交叉编译，install到rootfs中
2、PC交叉编译一个能用的gcc，install到rootfs中，再编译所需要的应用，再install？
感觉第二个方法可以玩一下试试👶 👶

@tigger 在 推荐一个好用开源的录屏软件 Captura 中说：

Captura-Portable.zip

这个录频软件确实好用！

378434f3-402c-4523-ae83-a0554f0f4fe5-image.png

需要重新配置 config，表示当前kernel中不存在.config配置文件，或者该配置文件与配置的arch不匹配

@whycanservice2 好的，了解了

@dort91011 在 米尔的T507，开机需要摁onoff。可以禁用onoff吗 中说：

上电自启系统

引脚给 1V8就相当于自启动了吧？

@yanmingjian
用前面那个或许简单一些，后面那个是复合USB设备。

一般只要修改板级目录下面的 config.xml 就可以了：

device/softwinner/xxxx-yyyyy/overlay/frameworks/base/core/res/res/values/config.xml

<!-- Indicates that connected MAC randomization is supported on this device --> <bool translatable="false" name="config_wifi_connected_mac_randomization_supported">false</bool>

@whycanservice 不好意思，解决了解决了，原来是spi1的设置和rgb冲突了

只有sf读取命令，没有boot命令

@daizebin 好的，非常感谢

测试过了，应该是选的固件本身有问题
换一个就可以正常执行

@whycanservice2 好的大佬，感谢解惑，多谢

@newcastle 有需要的话，也可以使用ubuntu14，实测拿到的SDK，ubuntu14基本都可以正常编译过👏 👏 👏

问题

能够提供一个H264 新接口的编码DEMO ?

@axw_fae make包括了mboot

@whycanservice 这个主线的驱动列表可以在哪找到啊

@as3213406 在 为什么T507内核启动失败报undefined instruction错误？ 中说：

没有找到内核。

检查是否没有找到kernel，kernel地址是否正确，kernel压缩格式是否正确，kernel的配置格式是否正确，启动模式ramdisk和extlinux是否正确，安卓镜像打包是否损坏
