rk3506b移植lvgl_chess流程
将lvgl作为子模块
在本地通过sdl模拟运行
1
| cd /home/dky/workspaces/CChess && make TARGET=lvgl DBG=1 -j && ./build/lvgl/chess_lvgl
|
交叉编译

| export CROSS_COMPILE=/home/dky/workspaces_rk/prebuilts/gcc/linux-x86/arm/gcc-arm-10.3-2021.07-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-
export CC=${CROSS_COMPILE}gcc
make TARGET=lvgl DBG=1 LVGL_BACKEND=drm CC="$CC" PKG="$PKG_CONFIG" -j
|
还有一些变量的配置写在了lvgl.mk中
或者直接执行脚本自动设置交叉编译的变量
将代码拷贝到SD卡

| sudo mount -t drvfs F: /mnt/sdcard/
sudo umount /mnt/sdcard

| cp -r assets /mnt/sdcard/

关闭默认的ui，这两个启动脚本具体内容可以看附录

| /etc/init.d/S50systemui stop #kill正点原子的默认ui
/etc/init.d/S49weston stop #kill weston进程

[lvgl] started (viewport=480x854). Press Ctrl+C to quit.
