@asoul_ava 是个电源供电都加电容了。

@z15242116489 dts节点要放对应的i2c下面，你放dtsi是没法识别到设备的。

Flutter t113能跑不~·

IMG_7074.jpeg 我放几秒就卡死求指点

@zifeiyu 可以看一下Linux常用的通用终端文件传输协议（modem系列协议，有Xmodem, Ymodem, Zmodem三种，Y兼具速度和兼容性），可以在串口和网口终端传输，如果你使用RS485，则受限于串口的速率。

各位大佬在用的时候没有发现内存泄漏吗？好像是mpv导致的，有没有解决办法啊

@liuqiang UART转RS485 IC的流控通过IO脚进行方向控制，控制器本身并没有这种功能，需要在代码里添加相关GPIO操作

我想基于T113-S3的板子来测试一下jailhouse，在使能root-cell的时候需要检测CPU运行模式为HYP，现在运行模式是SVC，测试不了

@huerli 大佬解决了吗 我也遇到这个问题

@zifeiyu https://bbs.aw-ol.com/topic/1701/tina-linux-存储介质切换-emmc-spi-nand-spi-nor-sd-card-sd-nand/2?_=1701672096020&lang=zh-CN

@awwwwa 好的谢谢

根据选择的overlay方式而定

@maihuanyi 在lichee/linux-5.4/drivers/staging/exfat/exfat_super.c的4027行添加延时，如下图所示7d661e07-2db4-4cae-a461-0d93a11beaf5-image.png
主要问题是exFAT初始化过快，需要等sd初始化完成，再初始化exFAT文件系统。

可以写一下rtt 移植的过程吗

把t113换成d1s，能启动了、

@wanglang 赞。👍 👍

@jacky502

&keyboard0 { key0 = <210 0x160>; wakeup-source; status = "okay"; };

注册gpio-keys 绑定键值，或者gpio-keys增加wakeup-source;

D1-H RT-Thread 官方支持

AWOL 支持这些芯片，提供SDK下载

参考 https://www.aw-ol.com/docs 中的文档下载

其他芯片需要联系你购买商家的客服或者代理获取

@fuzhikun A33有Tina3.5，联系代理获取

@wupaul2001 大哥，你是用Tina系统吗？

@awwwwa Hello, I'm using a TinyVision Board, follwing the steps from here: https://tinyvision.yuzukihd.top/#/?id=下载-awol-tina-linux-bsp selecting V851se-tinyvision-tina

82fd08ae-1143-416b-8129-f52123d6ba93-image.png

After flashing the image on the SD card this is the result:

db3aad59-7aba-47cc-a4e3-e52716f5c1e1-image.png

But if I flash the SD Card with the pre-build image downloaded from the github repository, it works allways.

Please help to find a solution,

Thanks for your answer!

太棒啦，大佬~！

@myamoroso 在 T113S3 无法完全启动 中说：

I2C: FDT ERROR:fdt_set_all_pin:[twi0]-->FDT_ERR_BADPATH
FDT ERROR:fdt_set_all_pin:[twi1]-->FDT_ERR_BADPATH

检查一下是不是分区空间不够了

@zhangjun 分区表里删了这个分区

@shz18877605430 建立rfcomm节点后再连接

@yteraa 重新make之后再pack还是这个问题

问题已确认，ubuntu有个modem管理，/usr/sbin/ModemManager 会去管理4G模块，grep 发现里面有 option1 的操作，赶时间简单粗暴直接删除就可以了

@steven73
用的是什么存储介质启动？

完整打印看下

@daizebin 谢谢大佬

@zllfdd https://codeleading.com/article/55242723616/

@fuzhikun 烧录时候对于的log发一下看下

在menuconfig里面勾选了libstdcpp，但是在lib里面死活都没有这个.so文件

@zxyuser 转换芯片这边的输入、输出信号，还有就是这个转换芯片的配置是否都正确。

mr813是支持hs400模式么？这个模式下，速度不应该是这么慢才对，测试了其他平台，差距还是挺大的，寻求回答，不知道哪里出问题了，测试的数据单位是MB/s

uboot的设备树和kernel的设备树都需要配置

初级485功能介绍

初级485功能是选定一个外部gpio脚，用于TTL->485转换芯片的发送使能功能

但此gpio具体要接在转换芯片的哪一个管脚上，以及高低电平代表的含义，以转换芯片的使用手册为准

典型MAX3485电路链接：https://www.elecfans.com/dianzichangshi/20180118618448.html

DE和RO为使能管脚。DE为低电平、RE为低电平时为接收；DE为高电平、RE为高电平时为发送；RO和DI为数据管脚。RO为接收，DI为发送；因此我们经常将DE和RE直接连接，用一个IO口控制。

dts配置

需要添加以下三个成员：

sunxi,uart-rs485 0：485模式关闭 1：485模式使能 sunxi,uart-485fl 0：485 gpio管脚数值为0时表示发送状态 1：485 gpio管脚数值为1时表示发送状态 sunxi,uart-485oe-gpios 用于外部转换芯片使能信号的gpio引脚，GPIO_ACTIVE_HIGH含义为默认为高电平

示例：

uart1: uart@2500400 { ... status = "okay"; //添加以下三行 sunxi,uart-rs485 = <1>; sunxi,uart-485fl = <1>; sunxi,uart-485oe-gpios = <&pio PG 8 GPIO_ACTIVE_HIGH>; };

查看了《User_Manual》，大概可以在驱动源码里去配置CER和CCR寄存器，打开这个capture捕获功能，配置输入捕获模式
effb552d-51e0-4713-a12f-463261c55946-image.png

读这几个寄存器的值，默认都是0x0，即disabled，默认是没有输入捕获功能的。手册中也没有介绍要如何在设备树中配置，最好还是在驱动源码中手动使能。

GPU 安卓部分是正常的，linux 部分才有这个问题，我使用的是 linux，不适用安卓。

@vermounth 在 T113 u-boot编译失败，没有brandy-2.0/spl目录 中说：

有哪位大佬知道，求原因

一般不开放，你从哪里拿到的SDK？可以找代理商申请一下SPL的源码，但是要说明原因，不然不一定给

@gaowei15537316965 在 f1c100s可以改成rgb565，是不是只需要修改设备树就可以了？ 中说：

rgb888

由于我通过 VGA DAC 将设备连接到 VGA 显示器，因此我使用 dumb_vga_dac 驱动程序。
该驱动程序允许您选择多种模式。 这就是为什么我“即时”切换模式。

您正在使用驱动程序 "panel-simple"。 该驱动程序仅允许一种模式。

对于 16 位，最有可能需要指定格式：

.bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG,

但不是
.bus_format = MEDIA_BUS_FMT_RGB565_1X16,

无论如何，在 sun4i_tcon.c 驱动程序中，sun4i_get_pixel_depth 函数提到了格式

MEDIA_BUS_FMT_RGB666_1X7X3_SPWG

需要尝试一下。

@tattoo1993 已解决，修改库spidev.c里的buffer大小即可。

@bigzhu Longan和Tina3.0是一个阶段的产物，后面SDK优化、升级，逐渐延伸出来了Tina4.0，Tina5.0

通俗点讲，Longan就是很老版本的全志SDK

@k123456
g2d_fd是打开的/dev/g2d，能正常运行

@xiaowenge 非常感谢，马上试试

你好 想请教一下 具体代码怎么实现的 能分享一下源码吗 感谢您

linux下的ipc阻塞超时时间的计算好像也是这样。涉及到更新时间的应用搭配超时相关都要小心，处理好其中的逻辑

@easy123

f1c100s\tina\lichee\linux-3.10\drivers\video\sunxi\disp\disp\dev_fb.c
文件中的frambuffer配置改一下
2.fbx format 配置改一下

@awwwwa 好的，谢谢

已放弃，勿回复。

这里需要注意一下，T113使用EMMC介质启动的话，若是使用UDISK分区作为overlayfs的挂载目录，在使用dd等读写指令的时候，会比使用rootfs_data慢
所以目前EMMC介质、且使用busybox的的方案，推荐使用rootfs_data作文overlayfs的底层目录

@fans168168 主板输出颜色255的时候，对应屏幕的颜色是64，所以一定是高位对齐，低位悬空，你这是低位对齐，高位悬空，肯定颜色会有问题

设置透明层

@liu11372650 可以将所有的 ”backtrack : xxx “ 拷贝到source下的一个文本文件（如ba.txt）中，然后确保source 了环境变量后，执行 callstack xxxx (xxxx就是你的文本文件名字，如 callstack ba.txt)，就会将死机前的栈进行回溯，得到死机前的函数调用流程。 从这里看，你这个应该是init模块装载orange时出问题了，或者orange初始化流程出问题了，可以检查一下。

uhttpd 是 个luci 应用

@awwwwa 感谢回复！glmark2 安卓才有，linux 下测试只能自己移植吗，我这边使用的是 Linux，不采用安卓系统。

另外我参考文档，能不能直接找到 EGL 跟 GLES 的库，加上图中的例程代码直接编译运行？

我找到安卓下有提供到库，但很难编译通过（使用 longan/build/toolchain 中gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu.tar.xz ）
