009 Embedded Linux-ARM. StorageQueries and discussion related to usage of Linux on ARM based devices. Linux has been ported to a variety of CPUs which are not only primarily used as the processor of a desktop or server computer, but also ARM, AVR32, ETRAX CRIS, FR-V, H8300, IP7000, m68k, MIPS, mn10300, SuperH, and Xtensa processors, It is also used as an alternative to using a proprietary operating system and toolchain. » 009.04.Boot Loaders
009.04.91.32. How does the `08_fallback_counting` script contribute to ensuring reliable booting in GRUB2? Can you explain its core functionalities in managing boot counters and fallback behavior?
Main functions :- insmod increment - It loads `increment` module which increments or decrements values in GRUB2's env variables.
boot_counter and boot_success - It checks if `boot_counter` variable is set ( if boot tracking is in place ) and also if `boot_success` variable is set to "0" ( boot failure ). It decides whether to proceed with fallback behaviour.
