@aldfaaa OTG接口连电脑，修改之前只有用flash可以这么烧录，用tf卡要拔卡用读卡器烧录。按键楼主的方法修改后，用tf卡也能直接OTG烧录。

T113芯片配置MIPI屏幕，设备树参照芒果的教程（https://bbs.aw-ol.com/topic/808/小麻雀直接驱动树莓派的dsi屏）已改，但是编译好不亮屏。查手册有说到要修改内核配置。

手册上说是这个路径：

这是我的配置界面，没有该项可选

芒果MQ-R t113-S3 + 800X480 4.3寸屏（亮度50%）电源输入显示5V 0.16A，整机功耗基本就是1W以内。接一个2500mah电池，待机可以达到5个小时

这不来个视频演示？

很强用芒果MQ-R接喇叭，播放能出声，但声音很小听个响，关键是开机后喇叭严重发烫

@yuzukitsuru 感谢回复，我自己摸索解决了。
我用LonganSDK，参照/etc/init.d/rcS里的开机启动脚本，用下面这个指令可以正常启动QT的app

#  /etc/qtenv.sh & ./analogclock

[1] 16558
/etc/qtenv.sh: line 17: [: too many arguments
add /dev/input/event5 to Qt Application.
find qt5 installed done
xkbcommon: ERROR: failed to add default include path /usr/share/X11/xkb
Failed to create xkb context

这个xkbcommon: ERROR 报错不影响使用，就没管他

huanian

已解决，引脚重复配置的问题，把PB2重复的地方去掉就可以

huanian

支持方向+AB键同时操作吗

这是t113 linux下的错误提示：

# ./analogclock
./analogclock: error while loading shared libraries: libQt5Gui.so.5: cannot open shared object file: No such file or directory

此文件是存在的

# cd  /usr/local/Qt_5.12.5/lib/                         
# find ./ -name  libQt5Gui.so.5
./libQt5Gui.so.5
#

在PC端查看的analogclock的文件属性：

$ file analogclock

期待楼主打板做出成品来

@captain D1咋把控制台弄到hdmi上呢？
https://bbs.aw-ol.com/topic/1320/share/4 参照这个设置好menuconfig

huanian

@yuzukitsuru 在 D1咋把控制台弄到hdmi上呢？中说：

然后驱动勾选

照这个方法设置，可以输出log到LCD上，但是屏上的字符显示会抖动，屏驱动没问题显示图片或文本截图是正常的。
