1 RKNN_DEMO分辨率适配
1、创建指定分辨率的配置文件
原配置文件目录：
buildroot/output/rockchip_rk1808/build/rknn_demo-
1.0.0/minigui/MiniGUI-1280x720.cfg
在相同目录下创建 MiniGUI-480x480.cfg，将文件内容的1280x720改成
480x480分辨率
2、选中指定配置cfg文件
目录：buildroot/package/rockchip/rknn_demo/rknn_demo.mk
1 ifeq ($(BR2_PACKAGE_RK1808),y)
2 RKNN_DEMO_MINIGUI_CFG=minigui/MiniGUI‐480x480.cfg
3 endif
3、清除编译记录，并重新编译完整镜像
rm buildroot/output/rockchip_rk1808/build/rknn_demo-1.0.0/.stamp_*
./build.sh
2 编译下载
硬件版型选择
./build.sh init
processing option: init

3 QT应用移植及打包编译过程
第一：查看buildroot/package/rockchip/apps/
1：编译QT qcamera 应用相关的 Config.in 与 qcamera.mk
/home/rpdzkj/rk3588/rk3588-linux/buildroot/package/rockchip/apps/qcamera
cat Config.in
config BR2_PACKAGE_QCAMERA
bool "qcamera"
depends on BR2_PACKAGE_QT5
help
Rockchip camera application based on QT
cat qcamera.mk
QCAMERA_VERSION = 1.0
QCAMERA_SITE = $(TOPDIR)/../app/qcamera
QCAMERA_SITE_METHOD = local
QCAMERA_LICENSE = ROCKCHIP
QCAMERA_LICENSE_FILES = LICENSE
define QCAMERA_INSTALL_TARGET_CMDS
mkdir -p $(TARGET_DIR)/usr/share/applications $(TARGET_DIR)/usr/share/icon
$(INSTALL) -D -m 0644 $(@D)/icon_camera.png $(TARGET_DIR)/usr/share/icon/
$(INSTALL) -D -m 0755 $(@D)/qcamera $(TARGET_DIR)/usr/bin/
$(INSTALL) -D -m 0755 $(@D)/qcamera.desktop $(TARGET_DIR)/usr/share/applications/
endef
$(eval $(qmake-package))
2：生效qcamera应用Config.in配置文件，重新执行刚修改的初始化文件,使之立即生效,而不必注销并重新登录。
source命令通常用于重新执行刚修改的初始化文件,使之立即生效,而不必注销并重新登录。
rpdzkj@ubuntu:~/rk3588/rk3588-linux/buildroot/package/rockchip/apps$ ls
apps.mk Config.in multivideoplayer qcamera qfm qlauncher qplayer qsetting
rpdzkj@ubuntu:~/rk3588/rk3588-linux/buildroot/package/rockchip/apps$ cat Config.in
source "package/rockchip/apps/multivideoplayer/Config.in"
source "package/rockchip/apps/qcamera/Config.in"
source "package/rockchip/apps/qfm/Config.in"
source "package/rockchip/apps/qlauncher/Config.in"
source "package/rockchip/apps/qplayer/Config.in"
source "package/rockchip/apps/qsetting/Config.in"
第二：配置QT qcamera应用，使其能够编译到output，最终打包到镜像中
