虽然出厂的程序可以点亮屏幕，但是后面发现38板rv1126下没有/dev/fb设备，因为要做ui设计，需要用到。自己倒腾，商家也没不说。搁了一段时间，最后看了正点原子开源资料，对比了kernel配置文件，发现有两处地方没选上.
fb0驱动配置
./build.sh BoardConfig-zhao-debug-spi-nand.mk （"BoardConfig-zhao-debug-spi-nand.mk"配置开发板信息 不同板子不一样 我的是NAND 256M)
进入kernel
make ARCH=arm rv1126_defconfig
make ARCH=arm menuconfig
进入配置
配置第一处：（温馨提示：使用快捷搜索 斜杠 / ）
配置第二处：
*代表编译进内核，M代表模块化（module）不编译进内核。
触摸功能适配

驱动加载gt9x
和前面操作类似
按 / （搜索快捷键）
按1跳到对应选项
空格一直按到*
make ARCH=arm savedefconfig //将.config 保存为 deconfig
cp defconfig arch/arm/configs/rv1126_defconfig //因为前面./build.sh编译脚本 配置文件是rv1126_defconfig
烧录
回到sdk根目录，编译内核
./build.sh kernel
编译完成后，打包镜像到rockdev
./mkfirmware.sh
在window下先进入 LOADER模式，虚拟机再接入，
烧录 完成。
sudo ./rkflash.sh
就有/dev/fb0了
这是我移植lvgl和qt的小demo，需要讲的是，触摸功能还是有问题，主要x轴数值到最后有个跳变的过程，解决思路1、改驱动 2、应用层自己做坐标转换
Qt 5.12
lvgl 8.2
