飞凌 OK113i-C 全志T113-i开发板初体验 [复制链接]

 

 板子做工精致很有份量，拿在手里沉甸甸的，各种接口一应俱全——USB、TF 卡座、SIM卡座、4G模块卡座、网口、RGB LCD接口、LVDS、RS485、CAN、各种音频口、TV-in/TV-Out，板上还自带一个RTL8723du wifi/蓝牙二合一模块，作为一块主打工业控制的主控板这些接口实属绰绰有余了。手里的板子是256MB内存+256MB nand flash版本（这个是低配版本，还有个512MB+8GB emmc的高配版本），飞凌开发文档中提到已经移植好了Qt5开发环境，所以这个内存跑跑Qt的UI程序是再合适不过了，可惜手里没有匹配的开箱即用的LCD显示屏不然接上直接能试试出厂自带的Qt测试程序了。 提供的开发资料中已经包含有Ubuntu 20.04 的虚拟机文件，因为是直接用的Linux版本系统，所以需要自己搭建开发环境，以下所涉内容都是在装有Ubuntu 20.04的PC上进行操作，而且，因为以前在安装过T113-S3的开发环境，所以在编译SDK过程中并没有碰到其他因缺少依赖软件报的错误。 ## T113-i longan linux开发环境搭建 ### 解压sdk ```shell cat OK113i-linux-sdk.tar.bz2* | tar jx -C ~/Dev/sdk/T113-i/ ``` ### 编译前的准备 除了 gcc，ncurse，bison，autoconf，wget，patch，texinfo，zlib，dos2unix 之外需要安装如下： ```shell sudo apt-get install git sudo apt-get install gnupg sudo apt-get install flex sudo apt-get install bison sudo apt-get install gperf sudo apt-get install build-essential sudo apt-get install zip sudo apt-get install curl sudo apt-get install libc6-dev sudo apt-get install libncurses5-dev:i386 sudo apt-get install x11proto-core-dev sudo apt-get install libx11-dev:i386 sudo apt-get install libreadline6-dev:i386 sudo apt-get install libgl1-mesa-glx:i386 sudo apt-get install libgl1-mesa-dev sudo apt-get install g++-multilib sudo apt-get install mingw32 sudo apt-get install tofrodos sudo apt-get install python-markdown sudo apt-get install libxml2-utils sudo apt-get install xsltproc sudo apt-get install zlib1g-dev:i386 sudo apt-get install gawk sudo dpkg-reconfigure dash 选择no sudo apt-get install libgl1-mesa-dev:i386 sudo apt install u-boot-tools ``` ### 初次编译内核 ```shell ./build.sh config Welcome to mkscript setup progress All available platform: 0. linux Choice [linux]: 0 All available board: 0. ok113i Choice [ok113i]: 0 All available flash: 0. default 1. nor 2. nand Choice [default]: 0 All available display_type: 0. tvout_pal 1. tvout_ntsc 2. lcd_800x480 3. lcd_1024x600 4. mipi_1024x600 5. lvds_1280x800 Choice [tvout_pal]: 2 Relocating the buildroot SDK from /home/forlinx/work/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host to /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host ... /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk File "<string>", line 1 import os.path; print os.path.relpath('/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/kernel/linux-5.4/arch/arm/configs/OK113I_linux_defconfig', '/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/kernel/linux-5.4/arch/arm/configs') ^ SyntaxError: invalid syntax ERROR: Can't find kernel defconfig! ``` python 报系统库语法错误，根据经验是系统python版本问题，首先查看系统中python版本号 ```shell python --version Python 3.8.10 ``` 不出意外的话编译系统依赖python 2.7，所以切换到python 2.7版本，具体操作如下： 首先，查看系统有几个python版本 ```shell update-alternatives --list python /usr/bin/python2 /usr/bin/python3 ``` 然后，通过如下切换到想要的版本 ```shell update-alternatives --config python There are 2 choices for the alternative python (providing /usr/bin/python).

编译生成的临时文件 │ ├── arch │ ├── block │ ├── certs │ ├── crypto │ ├── drivers #编译生成的驱动模块在此目录中 │ ├── fs │ ├── include │ ├── init │ ├── ipc │ ├── kernel │ ├── lib │ ├── Makefile │ ├── mm │ ├── modules.builtin │ ├── modules.builtin.modinfo │ ├── modules.order │ ├── Module.symvers │ ├── net │ ├── scripts │ ├── security │ ├── sound │ ├── source -> /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/kernel/linux-5.4 │ ├── System.map │ ├── usr │ ├── virt │ ├── vmlinux │ └── vmlinux.o └── staging └── sunxi.dtb #猜测是设备树 ``` 比如内核编译后wifi模块的驱动文件就存放在`OK113i-linux-sdk/out/kernel/build/drivers/net/wireless/rtl8723du`目录下的`8723du.ko` ### kernel menuconfig 配置 ```shell build.sh menuconfig ``` 上面设置的config居然是out目录下的文件，重新编译会被覆盖。 编译阶段打印使用这个配置`/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/kernel/linux-5.4/arch/arm/configs/OK113I_linux_defconfig`，试着改这个试试。 ### buildroot 编译 ```shell ./build.sh rootfs ``` 默认全部编译运行`build.sh`，会有如下打印有用信息，此处记录下： 编译Qt测试程序时候的打印 ```shell ... /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/bin/arm-linux-gnueabi-g++ -c -pipe -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os --sysroot=/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot -O2 -O3 -Wall -W -D_REENTRANT -fPIC -DQT_NO_UITOOLS -DQT_NO_DEBUG -DQT_WEBKITWIDGETS_LIB -DQT_PRINTSUPPORT_LIB -DQT_WIDGETS_LIB -DQT_WEBKIT_LIB -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -I. -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5 -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtWebKitWidgets -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtPrintSupport -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtWidgets -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtWebKit -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtGui -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtNetwork -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot/usr/include/qt5/QtCore -I. -I. -I/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/mkspecs/devices/linux-buildroot-g++ -o settings.o settings.cpp /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/bin/qmake -o Makefile /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/platform/framework/auto/qt_demo/terminal/terminal.pro ) && make -f Makefile build emmc rootfs PARTITION_FEX=/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/device/config/chips/t113_i/configs/ok113i/longan/sys_partition.fex ROOTFS_FEX_LINE=64 ROOTFS_FEX_STR= size = 2097152 ROOTFS_FEX_SIZE= 2097152 EXT4_SIZE=1073741824(1073741824/1024/1024) /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/device/config/chips/t113_i/configs/ok113i/longan/sys_partition.fex rootfs.fex size is2097152 EXT4_SIZE= 2097152*512=1073741824 Creating filesystem with parameters: Size: 1073741824 Block size: 4096 Blocks per group: 32768 Inodes per group: 8192 Inode size: 256 Journal blocks: 4096 Label: Blocks: 262144 Block groups: 8 Reserved blocks: 0 Reserved block group size: 63 Created filesystem with 8976/65536 inodes and 94920/262144 blocks /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/build/bin/make_ext4fs -s -l 1073741824 /home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/rootfs.ext4/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/target ``` 可以知道： 1. `sysroot` = `/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/arm-buildroot-linux-gnueabi/sysroot` 2. 移植好的qmake所在路径： `OK113i-linux-sdk/out/t113_i/ok113i/longan/buildroot/host/bin/qmake` 3. Qt示例工程源代码在`/home/luoyang/Dev/sdk/T113-i/OK113i-linux-sdk/platform/framework/auto/qt_demo`目录 4. 编译好的驱动模块都在`OK113i-linux-sdk/out/t113_i/ok113i/longan/dist`目录下面： ```shell OK113i-linux-sdk/out/t113_i/ok113i/longan/dist$ tree . ├── 8723du.ko ├── c2590_mipi.ko ├── gc030a_mipi.ko ├── gc0310_mipi.ko ├── gc2385_mipi.ko ├── gc5025_mipi.ko ├── imx278_2lane_mipi.ko ├── imx278_mipi.ko ├── imx386_2lane_mipi.ko ├── imx386_mipi.ko ├── md5.ko ├── modules.alias ├── modules.alias.bin ├── modules.builtin ├── modules.builtin.alias.bin ├── modules.builtin.bin ├── modules.dep ├── modules.dep.bin ├── modules.devname ├── modules.order ├── modules.softdep ├── modules.symbols ├── modules.symbols.bin ├── Module.symvers ├── nvp6158.ko ├── ov2680_mipi.ko ├── ov5640.ko ├── ov8858_r2a_4lane.ko ├── sha1_generic.ko ├── sp5409_mipi.ko ├── sunxi-ce.ko ├── vf-test.ko ├── xr819s.ko ├── xr829.ko ├── xradio_btlpm.ko └── xr_usb_serial_common.ko ``` ## 最后总结 板子出厂的rootfs中包含的基础软件是真的很全面，基本可以做到开箱即用了，wifi驱动也已经适配了，wpa_supplicant、bluealsa、bluez、alsa、tinyalsa等工具软件也已经包含。因为目前手头没有能直接可用的显示屏，所以HMI显示和视频解码等高级功能没法体验。不过对于喜欢折腾的先适配一块触摸显示屏还是很有必要的，这样可玩性更高。
