修改部分说明

H3-QPT平台, 变砖修复支持

镜像编辑/制作工具:

• h3/boom.sh : 用于生产镜像制作
• h3/repack_rootfs.sh : cpio.uboot 格式镜像的打包/解压工具
• start.sh [board:h3/h6] : fel-mass-storage 方式启动终端

快速修复:

• dd写入32MB的变砖修复数据到mmcblk0 (如果系统能起动,可直接写入,如果不能,使用fel-mass-storage方式写入)
• 终端重启,灯闪时按reset键,等待终端启动完成
• 用双头usb-type-a的线将设备otg接口连接到linux主机,用vfat格式化第四分区,并将三个分区备份文件写入该分区
• 终端重启,并按第2步,进入reset操作,自动完成变砖修复

Preparations

Linux and OS X

• compile and install sunxi-tools

• (optional) add udev rule to allow access to USB devices to users belonging to (previously created) "sunxi-fel" group:

SUBSYSTEMS=="usb", ATTR{idVendor}=="1f3a", ATTR{idProduct}=="efe8", GROUP="sunxi-fel"

Windows

• download Zadig

• connect board in FEL mode to your PC

• launch "Zadig"

• check "Options\List all devices"

• select device with VID=1F3A and PID=EFE8 (i.e. USB Device(VID_1f3a_PID_efe8))

• install "WinUSB" driver (tested on Win8.1 x86)

Notes

If eMMC is not detected, SD card will be exported instead

Some boards (like Orange Pi PC Plus) which don't have FEL button require using special SD image to enter FEL mode:

Use dd, Rufus or Etcher to flash fel-sdboot.img to SD card like any OS image and use this card to boot the board in FEL mode.
