Posted 2021-12-03 Neutionwei

1、键盘与2.4G无线遥控驱动文件

./common/usb_kbd.c

2、补丁添加

3、config配置

CONFIG_DM_KEYBOARD
CONFIG_USB_KEYBOARD
CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE

4、编译

./make.sh firefly-rk3399

5、烧写

把编译生成的uboot.img烧写到eMMC：

sudo ../tools/linux/Linux_Upgrade_Tool/upgrade_tool di -u uboot.img
