How to use fastboot and recovery mode

Note: Some additional packages might need to be installed to your ubuntu installation

1. Fastboot

Step.1 Connect PC (ubuntu base) and EDM1-CF-IMX6 with FAIRY baseboard using OTG usb cable. Step.2 Issue the u-boot command to enable fastboot mode:

>fastboot

Step.3 Issue the fastboot command on PC to flash the image. $ sudo fastboot flash system system.img Step.4 Observe the flash progress in u-boot and waiting flash to finish.

2. Recovery mode

Step.1 Recovery mode needs a ramdisk image to function with somethting like:

$ sudo mkimage -A arm -O linux -T ramdisk -C none -a 0x10800800 -n "Android Root Filesystem" -d ./out/target/product/$TARGET_DEVICE/ramdisk-recovery.img ./out/target/product/$TARGET_DEVICE/uramdisk.img

Step.2 To quick test, replace uramdisk on boot partition (partition 1) with recovery ramdisk. NOTE: In a production environment, both ramdisks need to coexist.
