Intro
Failsafe is the short name for the RAM bootable rescue image for APF boards (APF6 only for the moment). It is a Linux kernel + minimal initrd image all packed together in a standard apf6-linux.bin.
Installation
Generate it
$ make apf6failsafe_defconfig $ make $ cp buildroot/output/images/apf6-linux.bin /tftpboot/
Launch it
BIOS> run ramboot
Cool stuff that can be done with it
apf-config
# apf-config
- check eMMC filesystem
Backup eMMC rootfs
- you need a network connection with a server that can receive the backup:
# dd if=/dev/mmcblk2 bs=64k conv=noerror,sync | pv | gzip -c -9 > /tmp/root.bak.gz
